英语in a structured format怎么翻译？

不是啊，这篇文章主要修辞手法是讽刺，众所周知，第一颗原子弹在哪儿爆发后，它就成了死亡之城，正话反说，属于反讽。

动态语言有三个名词容易混淆：Dynamic Programming Language (动态语言或动态编程语言)Dynamically Typed Language (动态类型语言)Statically Typed Language (静态类型语言)定义所谓的动态类型语言，意思就是类型的检查是在运行时做的，比如如下代码是不是合法的要到运行时才判断（注意是运行时的类型判断）：def sum(a, b):return a + b静态类型而静态类型语言的类型判断是在运行前判断（如编译阶段），比如C#、java就是静态类型语言，静态类型语言为了达到多态会采取一些类型鉴别手段，如继承、接口，而动态类型语言却不需要，所以一般动态语言都会采用dynamic typing，常出现于脚本语言中.需要明确说明一点，那就是，是不是动态类型语言与这门语言是不是类型安全的完全不相干的，不要将它们联系在一起！优缺点静态类型语言的主要优点在于其结构非常规范，便于调试，方便类型安全；缺点是为此需要写更多的类型相关代码，导致不便于阅读、不清晰明了。动态类型语言的优点在于方便阅读，不需要写非常多的类型相关的代码；缺点自然就是不方便调试，命名不规范时会造成读不懂，不利于理解等。顺便说一下，现在有这样一种趋势，那就是合并动态类型与静态类型在一种语言中，这样可以在必要的时候取长补短，Boo就是一个很好的试验性例子.总体评价最后说一下Boo，Boo是一个静态类型语言，虽然用duck typing可以模拟dynamic typing，但是duck并不支持所有类型的操作替代，所以即使完全使用duck typing也不能达到dynamic typing。就像FantasySoft所述，Type Inference不是动态类型语言的特性，所以支持Type Inference不代表这门语言就是dynamically typed。未来发展在今天这个信息泛滥的时代，身为开发者，眼光比技术更重要。缺乏眼光的人，着眼于小，为细枝末节的所谓“创新”不惜肝脑涂地，赴汤蹈火，而面临真正变革时，或坐井观天，守旧拒新，或畏畏缩缩，裹足不前。具备眼光的人，着眼于大，平时稳扎稳打，不为世间纷扰所扰，一旦时机出现，则能抛却门户之见，枝节之争，以过人气概投身变革，成就自己的事业。这前后两者的差距之大，其实全在于对大趋势的把握上。回顾IT技术不长的历史，我们会发现，每当重大变革发生的时候，在技术圈子里总是存在激烈的争论，总有那些着眼于小的人站在细枝末节上对技术变革本身表示质疑甚至否定。当关系数据库和SQL语言把数据管理的繁琐工作从开发者和操作者身上解放出来的时候，有人抨击关系数据库性能低下；当微软开始用C语言开发PC应用程序时，汇编语言的拥护者轻蔑的说，只有汇编语言才能发挥PC机的全部能力；当Web进军企业计算时，一大批专家跑出来抨击HTML界面的呆板和HTTP协议的缓慢和幼稚。然而，所有这一切抱怨、质疑和信誓旦旦的否定，都被技术发展的大潮无情的吞噬，消失得无影无踪。原因很简单，所有这些声音，都是着眼于小，着眼于私，一叶障目，而不见IT技术发展的大势。IT技术发展的大趋势永远都是要更快，更简单。从这个角度来看待动态语言，结论就异常的清晰。在今天这个时代、动态语言代表着更快更简单的技术大趋势，因此它将必然成为未来构建软件和互联网技术的主角。回顾2006年国内外动态语言的发展历程，也恰恰能够印证这一点。By rainsEgo:不否认动态语言的各种好处，但是到了2011年，还请大家考虑一下scala这样的静态语言对动态语言造成的冲击。

云计算大火，如果你到现在还不知道云计算是什么意思，那你可就太low了！今天，就来跟大家说说，云计算是什么意思。云计算(cloud computing)是一种基于因特网的超级计算模式，在远程的数据中心里，成千上万台电脑和服务器连接成一片电脑云。因此，云计算甚至可以让你体验每秒10万亿次的运算能力，拥有这么强大的计算能力可以模拟核爆炸、预测气候变化和市场发展趋势。用户经由电脑、笔记本、手机等方式接入数据中心，按自己的需求进行运算。IBM的创立者托马斯·沃森曾表示，全世界只需要5台电脑就足够了。比尔·盖茨则在一次演讲中称，个人用户的内存只需640K足矣。李开复打了一个很形象的比喻：钱庄。早先人们只是把钱放在枕头底下，后来有了钱庄，很安全，不过兑现起来比较麻烦。现在发展到银行可以到任何一个网点取钱，甚至用ATM，或者国外的渠道。就像用电不需要家家装备发电机，直接从电力公司购买一样。云计算就是这样一种变革——由谷歌、IBM这样的专业网络公司来搭建计算机存储、运算中心，用户用一根网线借助浏览器就可以很方便的访问，把“云”做为资料存储以及应用服务的中心。云计算是什么意思？狭义的云计算是指IT基础设施的交付和使用模式，指在网络中，以按需、易扩展的方式获得所需的资源(硬件、平台、软件)。提供资源的网络被称为“云”。“云”中的资源在使用者看来是可以无限扩展的，并且可以随时获取，按需使用，随时扩展，按使用付费。这种特性经常被称为像水电一样使用IT基础设施。广义的云计算是指服务的交付和使用模式，指依靠网络以按需、易扩展的方式获得所需的服务。这种服务可以是IT和软件、互联网相关的，也可以是任意其他的服务。经过这次讲解，你现在明白云计算是什么意思了吗？

总结一下有如下几个要点：1.进程0是所有其他进程的祖先,也称作idle进程或swapper进程.2.进程0是在系统初始化时由kernel自身从无到有创建.3.进程0的数据成员大部分是静态定义的，即由预先定义好的INIT_TASK,INIT_MM等宏初始化.进程0的描述符init_task定义在arch/arm/kernel/init_task.c,由INIT_TASK宏初始化。init_mm等结构体定义在include/linux/init_task.h内，为init_task成员的初始值,分别由对应的初始化宏如INIT_MM等初始化Process1进程0最终会通过调用kernel_thread创建一个内核线程去执行init函数，这个新创建的内核线程即Process1(这时还是共享着内核线程0的资源属性如地址空间等)。init函数继续完成剩余的内核初始化,并在函数的最后调用execve系统调用装入用户空间的可执行程序/sbin/init,这时进程1就拥有了自己的属性资源，成为一个普通进程(init进程)。至此，内核初始化和启动过程结束。下面就进入了用户空间的初始化，最后运行shell登陆界面。(注：Init进程一直存活，因为它创建和监控在操作系统外层执行的所有进程的活动。)——————这段对进程0的描述引用自《UnderstandingTheLinuxKernel-ThirdEdtion》Theancestorofallprocesses,calledprocess0,theidleprocess,or,forhistoricalreasons,theswapperprocess,isakernelthreadcreatedfromscratchduringtheinitializationphaseofLinux.Thisancestorprocessusesthefollowingstaticallyallocateddatastructures(datastructuresforallotherprocessesaredynamicallyallocated)

Commercialising autonomous vehicles：Gently does it A six-month trial in Texas focuses on what self-driving technology can do now 在得克萨斯州一项为期六个月的试验将检验自动驾驶技术能做到什么 NOBODY likes it when a taxi takes longer than expected to arrive. But that is what is happening with self-driving cars. Building a vehicle that can handle a busy street, with cyclists, pedestrians, roadworks and emergency vehicles, is a tall order. In March a pedestrian was killed in Tempe, Arizona when a self-driving Uber vehicle failed to spot her as she wheeled her bicycle across an empty road at night, and the vehicle"s safety driver failed to hit the brakes. There is a growing sense that the technology has, so far, over promised and under delivered. So a trial of self-driving vans that began in Frisco, Texas on July 30th is notable for its realistic approach to what the technology can do today. Drive.ai, a startup, has deployed seven minivans to transport people within a limited area of the city that includes an oufb03ce park and a retail area. “We are identifying a valuable use case that we can deploy with today"s technology,” says Andrew Ng, a board member and a pioneer of “deep learning”, the technique that underpins the current boom in artifcial intelligence. As the technology evolves, he says, so will autonomous-vehicle services. For now, though, Drive.ai is keeping things simple. All pick-ups and drop-oufb00s happen at designated stops, to minimise disruption as passengers get on and oufb00. Riders hail the vans using an app and go to the nearest stop; a vehicle then appears to pick them up. (The vehicles do not circulate continuously like shuttle buses, but wait to be called, and plan their routes dynamically.) Use of the service is free of charge for now. The vans are painted a garish orange and clearly labelled as self-driving vehicles. “We weren"t going for pretty, we were going for distinctive,” says Mr Ng, who draws an analogy with yellow school buses: people understand that some kinds of vehicles behave in particular ways, and accommodate them accordingly. Screens mounted on the vans" exteriors let them communicate with pedestrians and other road users, for example to tell a pedestrian that it is safe to cross a road. Rather than trying to build a vehicle that mimics a human-piloted one, Drive.ai is making the self-driving nature of its vehicles explicit.

它会出现在 /proc/devices 和 sysfs 中.如同大部分内核函数, 如果分配成功进行, register_chrdev_region 的返回值是 0. 出错的情况下, 返回一个负的错误码, 不能存取请求的区域.4．下面是char_device_struct结构体的信息fs/char_dev.cstatic struct char_device_struct {struct char_device_struct *next;

goto out;(6)到达这里，就表明主设备号major已经有合法的值了，接着进行char_device_struct变量的初始化。设置major, baseminor, minorct以及name。2.将char_device_struct变量注册到内核(7)将 i 赋值成 major_to_index(major)将major对256取余数，得到可以存放char_device_struct在chrdevs中的索引(8)进入循环，在chrdevs[i]的链表中找到一个合适位置。退出循环的条件：(1)chrdevs[i]为空。(2)chrdevs[i]的主设备号大于major。(3)chrdevs[i]的主设备号等于major，但是次设备号大于等于baseminor。注意：cp = &(*cp)->next，cp是char_device_struct **类型，(*cp)->next是一个char_device_struct *类型，所以&(*cp)->next，就得到一个char_device_struct **，并且这时候由于是指针，所以对cp赋值，就相当于对链表中的元素的next字段进行操作。(9)进行冲突检查，因为退出循环的情况可能造成设备号冲突(产生交集)。如果*cp不空，并且*cp的major与要申请的major相同，此时，如果(*cp)->baseminor < baseminor + minorct，就会发生冲突，因为和已经分配了的设备号冲突了。出错就跳转到ret = -EBUSY; goto out;(10)到这里，内核可以满足设备号的申请，将cd链接到链表中。(11)释放chrdevs_lock读写锁，开中断，开内核抢占。(12)返回加入链表的char_device_struct变量cd。(13)out出错退出a.释放chrdevs_lock读写锁，开中断，开内核抢占。b.释放char_device_struct变量cd，kfree。c.返回错误信息 下面程序出自fs/char_dev.c动态申请设备号...218 /**219 * alloc_chrdev_region() - register a range of char device numbers220 * @dev: output parameter for first assigned number221 * @baseminor: first of the requested range of minor numbers222 * @count: the number of minor numbers required223 * @name: the name of the associated device or driver224 *225 * Allocates a range of char device numbers.

组织中细胞类型的空间位置从根本上塑造了细胞之间的相互作用和功能，but the high-throughput spatial mapping of complex tissues remains a challenge。We present сell2location , a principled and versatile Bayesian model（贝叶斯模型） that integrates single-cell and spatial transcriptomics to map cell types in situ in a comprehensive manner。在准确性和全面性的方面，cell2location的表现优异，In the mouse brain, we use a new paired single nucleus and spatial RNA-sequencing dataset to map dozens of cell types and identify tissue regions in an automated manner。We discover novel regional astrocyte subtypes including fine subpopulations in the thalamus and hypothalamus（新的发现）。In the human lymph node, we resolve spatially interlaced immune cell states and identify co-located groups of cells underlying tissue organisation.（细胞共定位）。我们在空间上绘制罕见的萌发前中心B细胞种群，并预测与干扰素反应相关的推定细胞相互作用。总之方法很好用。 这里我们需要注意的一点就是， 贝叶斯模型 ，这个模型在建模的时候很常用，这里就不多介绍了，推荐大家看一本书《机器学习原理、算法与应用》，书中讲述了很多有关机器学习的算法和基础知识，有利于我们加深生信分析的算法原理。 The cellular architecture of tissues, where distinct cell types are organized in space, underlies cell-cell communication, organ function and pathology.（组织是一个复杂的统一体）。Emerging spatial genomics technologies hold considerable promise for characterising tissue architecture, providing key opportunities to map resident cell types and cell signalling in situ, thereby helping guide in vitro tissue engineering efforts.（空间转录组的主要应用价值）。但是空间转录组仍然存在挑战，One reason is the enormous variation in tissue architecture across organs, ranging from the brain with hundreds of cell types found across discrete anatomical regions to immune organs with continuous cellular gradients and dynamically modified microenvironments。To create and map comprehensive tissue atlases, experimental and computational methods need to be aligned to cope with this variation and in particular, enable mapping numerous resident cell types across diverse and complex tissues in situ.（技术挑战）。 coupled single-cell and spatially resolved transcriptomics offer a scalable approach to address these challenges（单细胞和空间转录组的技术互补）。首先第一步要从解离的组织中识别各种细胞类型（单细胞转录组），然后匹配各个细胞类型的空间位置分布。目前的挑战是First, spatial RNA-seq measurements (i.e. locations) combine multiple cell types as array-based mRNA capture currently do not match cellular boundaries in tissues. Thus, each spatial position corresponds to either several cell types (Visium, Tomo-Seq) or fractions of multiple cell types (Slide-Seq, HDST). Second, spatial RNA-seq measurements are confounded by different sources of variation as 1) cell numbers vary across tissue positions, 2) different cells and cell types differ in total mRNA content, and 3) thin tissue sectioning captures variable fractions of each cell"s volume. Computational approaches need to appropriately model and account for all of these factors。 Here, we present cell2location, a principled and versatile Bayesian model for comprehensive mapping of cell types in spatial transcriptomic data.（我们关注的重点）Cell2location uses reference gene expression signatures of cell types derived from scRNA-seq to decompose multi-cell spatial transcriptomic data into cell type abundance maps（简单的原理与其他方法相同，算法有差异）。The model accurately maps complex tissues, including rare cell types and fine subtypes, and it identifies tissue regions and co-located cell types downstream in an automated manner（能够识别共定位的细胞类型，这个很重要）。下面是两个应用案例，证明这个方法好。 Cell2location maps the spatial distribution of cell types by integrating single-cell RNAseq (scRNA-seq) and multi-cell spatial transcriptomic data from a given tissue。 我们首先解决一下J-S散度和PR曲线。 KL散度又称为相对熵，信息散度，信息增益。KL散度是是两个概率分布P和Q 差别的非对称性的度量。 KL 散度是用来 度量使用基于Q的编码来编码来自P的样本平均所需的额外的位元数。 典型情况下，P表示数据的真实分布，Q表示数据的理论分布，模型分布，或P的近似分布。 定义如下： 因为对数函数是凸函数，所以 KL散度的值为非负数。 相对于PR曲线，ROC曲线了解的更多一些，大家可以参考我关于ROC曲线的讲解 深入理解R包AUcell对于分析单细胞的作用 . 而PR曲线 模型的简单介绍 For a complete derivation of the cell2location model, please see supplementary computational methods. Briefly, cell2location is a Bayesian model, which estimates absolute cell density of cell types by decomposing mRNA counts U0001d451 s,g of each gene U0001d454 = {1, . . , U0001d43a} at locations U0001d460 = {1, . . , U0001d446} into a set of predefined reference signatures of cell types g f g .For 10X Visium data, this matrix can be directly obtained from the 10X SpaceRanger software and imported into data format used in a popular python package Scanpy(利用scanpy来读取10X分析数据，也可以联合Suerat进行分析)。d s,g should be fltered to a set of genes expressed in the single cell reference g f g .这个地方的处理在于单细胞与空间转录组映射的时候，表达基因的相同。cell2location的图表模型如下图：

单词不会，你不懂，单词会了，语法你不知道，你就不知道从那里翻译开始，我给你来个句子，你看看tremendouly conspicuous is that how to protect our environment from contamination didn"t capture people attention in the past decades when science and technology was under-developed，while at present the situation has been turning around我是一个高考的过来人。首先我想请阁下明白一个道理冰冻三尺非一日之寒，所以坚持很重要，英语是一门很看重积累的科目。 虽然我高考已经好多年了，而且今年即将大学毕业，踏入社会。但英语一直没有丢，英语一直是我的排头兵！我对英语的自信还有，我觉得学好英语不难，重要的是你要有恒心，急躁冒进，三天打渔两天晒网都是不行的。在这里我就毛遂自荐一下我的学习方法吧： 首先先你要端正心态，不要急躁，，你做你自己的事，这样才能静下心来学习。要成为英语高手就必须比别人走更多的路，做更多的事。你应该明白一个事实，英语是单词和语法的综合，所以单词和语法都要拿下。 其次，对于单词，有如下几种方法，第一个，是加强记忆的频度，也就是说，早上记了几个，隔几个小时又看一次，总之一天之内，记忆的间隔不要太长，否则你辛苦积累的记忆会随着时间的延长而淡化，第二个，是可以根据自己的理解编顺口溜，比如good morning 是狗摸你…（见笑了）…，第三个，最重要的是，记单词的时候，不要忘了阅读，一边记单词，一边看文章，这样可以把孤立的单词串联起来，记忆的效果会加倍，第四个。我建议你记单词要分门别类记忆，要形成一个意群，比如，重要性用magnitude magnificence ，表示非常，大大地有exceedingly，tremendously，extremely……这样做在你写作时，是十分有好处的，写作时不要尽写一些低级词汇，你要写高级词汇，比如重要性写magnitude，许多写a multitude of 或者handsome。再次，是语法。学习语法，首先要明白什么是主谓宾定状补，什么是系动词，什么是直接宾语，间接宾语，这些是学习语法的基础，语法是房子，主谓宾定状补等是沙石砖瓦 此外，对于完形填空以及阅读理解，那就只能靠平时的练习了，在这个过程中，你要时时总结，纵深对比，千万不要陷入题海战术只做题，不总结的误区当中。在做题的过程中，你把各种体型都总结了一遍，积累了丰富的经验，而且你还提升了自己的阅读速度，一举两得，所以做题是很重要的！其实，完形填空无非就是单项选择加语境分析，也就是说，做完形填空你的语法要好，而且你要积累比较多的固定搭配，短语，特殊用法等，完形填空的语法还是很重要的！对于阅读，我个人感觉是，纯粹是个人经验积累多少的问题，只有保证一定的练习量，你才能用质的提高！最后，我建议你，平时读报，或者做题的时候，发现有好的句子好的词汇，你要抄下来，长期下来，你的作文会有提高的，需要说明的是，这个提高过程可能很缓慢，但是最后能收到很好的效果，以前25分的作文我都能保证在21-23这个级别，靠的就是对语法的熟练掌握和积累了许多较高级的词汇，句型，句子。我个人的理解是，在你的语法达到基本不会出错的程度上，作文便应该以词汇取胜，因为在这个层次上，大家的语法都差不多，没什么变化，唯一有变化的就是你的词汇！给你打个比方吧，很多想到“许多”就用many，但是你别忘了many a ；handsome；massive，innumerable；很多人想到“专家”就写expert，但很少人会想到specialist，很多人在想到“擅长”这词，就写be good at ，却不知还有更高级的表达法：be expert at 或者excel in ……高手和庸才，就体现在这些细微的差别上 ！！

2.2 embedded real-time operating system operation managementTo realize the flexible complete scheduling mechanism, improve system performance, it is embedded scheduling operating system to manage system. Mu C/OS - II is a free open source, structure compact, can be deprived of the real-time kernel real-time operating system, its core task scheduling and management, provide time management, synchronization and communication between tasks, memory management and interrupt service etc. Function. It is suitable for small control system, a high efficiency, occupancy space, good real-time performance and extensible, etc. Can be compiled to minimum kernel 2K around.Maximum tire-road friction coefficient C/OS - II real-time kernel by hand, not support scheduling strategy of time round, core is always scheduling operation under the condition of the readiness of the highest priority task. In the concrete implementation can according to the characteristics of the wireless scheduling system will be divided into multiple tasks, each task gives a clear and other tasks of different priority, according to each task priority, dynamically switched each task, so as to ensure the requirement of real-time. If you want a task priority according to the condition of change and change, can be called the change task priority function.3 scheduling task division and designMore than 31,000 task partitioningThe main task and interrupt divided according to the functions of the equipment to perform operation platform, each task to differentiate between tasks and responsibilities clear information exchange and synchronous mutexes should be short and concise, task priority clearly defined.Wireless equipment tasks scheduling platform can be divided into four mission statement: equipment, information distribution task, task, receiving task token round task. The main mission statement equipment, equipment, equipment identity authentication in network is the statement from equipment, equipment or if the equipment is in operation platform, from the star network equipment directly to join the new network. Information distribution function is the task, equipment and network information data sending specified in the equipment. Information on serial interrupt receiving task is to trigger the role is to receive the network, the data and main equipment of sending back from equipment or token. Token round the main task for the equipment is established, when completed, the scheduling network nodes in the network equipment according to information stored separately open storage area (the node number) distribute tokens information, the general situation is according to the node number, from big to small token of nodes is the current network activity node. For from equipment, token round task finished only token return functions.

　　SQL Server执行动态SQL的话 应该如何实现呢?下面就为您介绍SQL Server执行动态SQL两种正确方式 希望可以让您对SQL Server执行动态SQL有更深的了解 　　动态SQL:code that is executed dynamically 它一般是根据用户输入或外部条件动态组合的SQL语句块 动态SQL能灵活的发挥SQL强大的功能 方便的解决一些其它方法难以解决的问题 相信使用过动态SQL的人都能体会到它带来的便利 然而动态SQL有时候在执行性能(效率)上面不如静态SQL 而且使用不恰当 往往会在安全方面存在隐患(SQL 注入式攻击) 　　动态SQL可以通过EXECUTE 或SP_EXECUTESQL这两种方式来执行 　　EXECUTE 　　执行 Transact SQL 批中的命令字符串 字符串或执行下列模块之一:系统存储过程 用户定义存储过程 标量值用户定义函数或扩展存储过程 SQL Server 扩展了 EXECUTE 语句 以使其可用于向链接服务器发送传递命令 此外 还可以显式设置执行字符串或命令的上下文 　　SP_EXECUTESQL 　　执行可以多次重复使用或动态生成的 Transact SQL 语句或批处理 Transact SQL 语句或批处理可以包含嵌入参数 在批处理 名称作用域和数据库上下文方面 SP_EXECUTESQL 与 EXECUTE 的行为相同 SP_EXECUTESQL stmt 参数中的 Transact SQL 语句或批处理在执行 SP_EXECUTESQL 语句时才编译 随后 将编译 stmt 中的内容 并将其作为执行计划运行 该执行计划独立于名为 SP_EXECUTESQL 的批处理的执行计划 SP_EXECUTESQL 批处理不能引用调用 SP_EXECUTESQL 的批处理中声明的变量 SP_EXECUTESQL 批处理中的本地游标或变量对调用 SP_EXECUTESQL 的批处理是不可见的 对数据库上下文所作的更改只在 SP_EXECUTESQL 语句结束前有效 　　如果只更改了语句中的参数值 则 sp_executesql 可用来代替存储过程多次执行 Transact SQL 语句 因为 Transact SQL 语句本身保持不变 仅参数值发生变化 所以 SQL Server 查询优化器可能重复使用首次执行时所生成的执行计划 　　一般来说 我们推荐 优先使用SP_EXECUTESQL来执行动态SQL 一方面它更加灵活 可以有输入输出参数 另外一方面 查询优化器更有可能重复使用执行计划 提高执行效率 还有就是使用SP_EXECUTESQL能提高安全性;当然也不是说要完全摈弃EXECUTE 在特定场合下 EXECUTE比SP_EXECUTESQL更方便些 比如动态SQL字符串是VARCHAR类型 不是NVARCHAR类型 SP_EXECUTESQL 只能执行是Unicode的字符串或是可以隐式转换为ntext的常量或变量 而EXECUTE则两种类型的字符串都能执行 　　下面我们来对比看看EXECUTE 和SP_EXECUTESQL的一些细节地方 　　EXECUTE(N SELECT * FROM Groups ) 执行成功 　　EXECUTE( SELECT * FROM Groups ) 执行成功 　　SP_EXECUTESQL N SELECT * FROM Groups ; 执行成功 　　SP_EXECUTESQL SELECT * FROM Groups 执行出错 　　Summary:EXECUTE 可以执行非Unicode或Unicode类型的字符串常量 变量 而SP_EXECUTESQL只能执行Unicode或可以隐式转换为ntext的字符串常量 变量 　　DECLARE @GroupName VARCHAR( );SET@GroupName = SuperAdmin ; 　　EXECUTE( SELECT * FROM Groups WHERE GroupName= + SUBSTRING(@GroupName ) + ); SUBSTRING 附近有语法错误 　　DECLARE @Sql VARCHAR( ); 　　DECLARE @GroupName VARCHAR( );SET@GroupName = SuperAdmin ; 　　SET@Sql= SELECT * FROM Groups WHERE GroupName= + SUBSTRING(@GroupName ) + 　　 PRINT @Sql;EXECUTE(@Sql); 　　Summary:EXECUTE 括号里面只能是字符串变量 字符串常量 或它们的连接组合 不能调用其它一些函数 存储过程等 如果要使用 则使用变量组合 如上所示 　　DECLARE @Sql VARCHAR( ); 　　DECLARE @GroupName VARCHAR( );SET@GroupName = SuperAdmin ; 　　SET@Sql= SELECT * FROM Groups WHEREGroupName=@GroupName 　　 PRINT @Sql;EXECUTE(@Sql); 出错:必须声明标量变量 “@GroupName” SET@Sql= SELECT * FROM Groups WHERE GroupName= + QUOTENAME(@GroupName ) 　　EXECUTE(@Sql); 正确: 　　DECLARE @Sql NVARCHAR( ); 　　DECLARE @GroupName NVARCHAR( );SET@GroupName = SuperAdmin ; 　　SET@Sql= SELECT * FROM Groups WHEREGroupName=@GroupName 　　PRINT @Sql; 　　EXEC SP_EXECUTESQL @Sql N @GroupNameNVARCHAR @GroupName 　　查询出来没有结果 没有声明参数长度 　　DECLARE @Sql NVARCHAR( ); 　　DECLARE @GroupName NVARCHAR( );SET@GroupName = SuperAdmin ; 　　SET@Sql = SELECT * FROM Groups WHERE GroupName=@GroupName 　　PRINT @Sql; 　　EXEC SP_EXECUTESQL @Sql N @GroupName NVARCHAR( ) @GroupName 　　Summary:动态批处理不能访问定义在批处理里的局部变量 SP_EXECUTESQL 可以有输入输出参数 比EXECUTE灵活 　　下面我们来看看EXECUTE SP_EXECUTESQL的执行效率 首先把缓存清除执行计划 然后改变用@GroupName值SuperAdmin CommonUser CommonAdmin分别执行三次 然后看看其使用缓存的信息 　　DBCC FREEPROCCACHE; 　　DECLARE @Sql VARCHAR( ); 　　DECLARE @GroupName VARCHAR( );SET@GroupName = SuperAdmin ; CommonUser CommonAdmin 　　SET@Sql = SELECT * FROM Groups WHERE GroupName= + QUOTENAME(@GroupName ) 　　EXECUTE(@Sql); SELECTcacheobjtype objtype usecounts sql 　　FROM sys syscacheobjects 　　WHERE sql NOTLIKE %cache% 　　ANDsql NOTLIKE %sys % ; 　　依葫芦画瓢 接着我们看看SP_EXECUTESQL的执行效率 　　DBCC FREEPROCCACHE; 　　DECLARE @Sql NVARCHAR( ); 　　DECLARE @GroupName NVARCHAR( );SET@GroupName = SuperAdmin ; CommonUser CommonAdmin 　　SET@Sql = SELECT * FROM Groups WHERE GroupName=@GroupName 　　EXECUTESP_EXECUTESQL @Sql N @GroupName NVARCHAR( ) @GroupName; 　　SELECTcacheobjtype objtype usecounts sql 　　FROM sys syscacheobjects 　　WHERE sql NOTLIKE %cache% 　　ANDsql NOTLIKE %sys % ; lishixinzhi/Article/program/SQLServer/201311/22279

总结一下有如下几个要点：1.进程0是所有其他进程的祖先,也称作idle进程或swapper进程.2.进程0是在系统初始化时由kernel自身从无到有创建.3.进程0的数据成员大部分是静态定义的，即由预先定义好的INIT_TASK,INIT_MM等宏初始化.进程0的描述符init_task定义在arch/arm/kernel/init_task.c,由INIT_TASK宏初始化。init_mm等结构体定义在include/linux/init_task.h内，为init_task成员的初始值,分别由对应的初始化宏如INIT_MM等初始化Process1进程0最终会通过调用kernel_thread创建一个内核线程去执行init函数，这个新创建的内核线程即Process1(这时还是共享着内核线程0的资源属性如地址空间等)。init函数继续完成剩余的内核初始化,并在函数的最后调用execve系统调用装入用户空间的可执行程序/sbin/init,这时进程1就拥有了自己的属性资源，成为一个普通进程(init进程)。至此，内核初始化和启动过程结束。下面就进入了用户空间的初始化，最后运行shell登陆界面。(注：Init进程一直存活，因为它创建和监控在操作系统外层执行的所有进程的活动。)——————这段对进程0的描述引用自《UnderstandingTheLinuxKernel-ThirdEdtion》Theancestorofallprocesses,calledprocess0,theidleprocess,or,forhistoricalreasons,theswapperprocess,isakernelthreadcreatedfromscratchduringtheinitializationphaseofLinux.Thisancestorprocessusesthefollowingstaticallyallocateddatastructures(datastructuresforallotherprocessesaredynamicallyallocated)

在语法上没有错误首先要掌握一点，构造函数、析构函数、虚函数可以声明为内联函数，这在语法上是正确的。 When the object is referenced via a pointer or a reference, a call to a virtual function cannot be inlined, since the call must be resolved dynamically. Reason: the compiler can"t know which actual code to call until run-time (i.e., dynamically), since the code may be from a derived class that was created after the caller was compiled. Therefore the only time an inlinevirtual call can be inlined is when the compiler knows the "exact class" of the object which is the target of the virtual function call. This can happen only when the compiler has an actual object rather than a pointer or reference to an object. I.e., either with a local object, a global/static object, or a fully contained object inside a composite.

1,“多媒体”这个术语描述了许多不同的技术,它使得视听媒体可以以交流为目的用新的方式结合起来。2.多媒体技术在商业领域的另一个重要实践是视频会议，就是在不同地方的两个或多个人通过使用计算机网络来传输音频和视频数据，从而进行会议。3.多媒体使得游戏的创新性，互动性体验得到了极大的提高，这是只有在有引人入胜的声音和耀眼的图形时才会有的感受。4,嵌入式系统是一种专用系统，在这种系统下计算机完全被它所控制的设备封装。5.一些嵌入式系统由于安全性和可用性的原因被要求必须满足实时性能。其它的一些可能有很低 的或者没有这样的性能要求，由此可以简化系统硬件以减少成本。6，万维网的崛起使嵌入式系统的设计师有了另一个很不同的选择，因为它是通过一个网络连接提供一个网页界面。7，一个设计良好的数据库,没有需要用户或使用者必须在同一时间内更新的重复数据。8.当运行数据库中的数据时，你必须使用由数据库软件定义的一套命令和声明(语言)9，通用的数据库应用程序可以使用目录为用户动态地提供不同的数据库的数据,而不会被绑在一个特定的数据格式。10，电子商务这个系统不仅包括着重于货物买卖的交易和直接产生利润的服务，还包括支持产生收入的交易11，电子商务是建立在传统商务的优点和结构上,再加上电子网络提供的灵活性。12，另外一个例子，安培公司，向客户提供机会直接从其网络目录购买电子接插件、relater组件，通过传达对EDI-based采购订单及确认的需要13，电讯通信常包括信息的发送者和一个或多个被连接的接受者,例如电话系统,是把信息从一个地方传递到另一个地方。14，此外，算法分解的广泛使用促成了不可扩展和不可复用的软件的设计和实现15，现有的面向对象的元件和框架主要集中在少数地区(e.g.GUIs），并且现有的行业标准还缺少在整个通信软件领域中真正有效的语义、特点、和互用性 纯手工翻译啊 。。。。累死我了。。。

在unity3d中实现动态环境光的效果，似乎可以用此方法来做出一天中不同时间的光线效果。下面是原文：I"ve been working on getting dynamic ambient lighting workingwithin Unity. Based off Valve"s 6-colour pre-baked ambient lighting(detailed here, pg 5, ch 8.4.1), but it grabs the 6 coloursdynamically.There"s probably lots more you could do to optimise it further(e.g. use replacement shaders when rendering the cubemap that dosimpler lighting calcs). But you could do that yourself asrequired.I"d also advise against using it on anything other than yourmain character, as it"s likely too expensive to run on multipleobjects.cubemap camera scriptCreate a new camera and turn off the GUI, Flare and Audiocomponents.Set up it"s Culling Layers to not render non-essential thingslike particles or incidental detail. Also move your character toit"s own layer and set the camera not to render it (we don"t wantbits of the character rendered into the cubemap).Attach this javascript to it and set the target to be yourcharacter and set up the offset from your character"s position sothat it"s in the centre of your character (i.e. a 2m tall characterwants to be offset 0, 1, 0 so that the camera renders from thecharacters centre.下面为摄像机脚本：@script ExecuteInEditModepublic var target : Transform;public var cubemapSize : int = 128;public var oneFacePerFrame : boolean = true;public var offset : Vector3 = Vector3.zero;private var cam : Camera;private var rtex : RenderTexture;function Start () {cam = camera;cam.enabled = false;// render all six faces at startupUpdateCubemap( 63 );transform.rotation = Quaternion.identity;}function LateUpdate () { if (oneFacePerFrame ) {var faceToRender = Time.frameCount % 6;var faceMask = 1 << faceToRender;UpdateCubemap ( faceMask ); } else{UpdateCubemap ( 63 ); // all six faces }}function UpdateCubemap ( faceMask : int ) {if ( !rtex ) {rtex = new RenderTexture ( cubemapSize, cubemapSize, 16 );rtex.isPowerOfTwo = true;rtex.isCubemap = true;rtex.useMipMap = true;rtex.hideFlags = HideFlags.HideAndDontSave;rtex.SetGlobalShaderProperty ( " _ WorldCube" );}transform.position = target.position + offset;cam.RenderToCubemap ( rtex, faceMask );}function OnDisable () {DestroyImmediate ( rtex );}dynamic ambient shader环境光shaderThis is the shader that generates and applies the ambientlighting from the cubemap rendered by the camera above.Create a new shader, paste this code into it and save it.

NOTE: Use the -d option when running Licrqst.exe to decompress the file and recreate the proper directory structure. MORE INFORMATIONThe LicReqst sample is a dialog-based MFC application that illustrates how to use the IClassFactory2 interface to request an object"s License key. LicReqst displays the ProgID of each of the currently registered ActiveX controls in a Listbox. When one of the displayed ProgID"s is selected, an instance of the corresponding control is created and then asked for it"s License key. If a valid key is returned, LicReqst displays the key and enables the "Copy to Clipboard" button that allows the License key to be copied to the Clipboard. The License key can then easily be pasted into code that uses the CWnd::CreateControl method to dynamically create an instance of the Control. LicReqst creates a textual version of the License key data in the form of a declaration of an array of WCHAR when copying the key to the Clipboard. This is done because the License key data could contain non-printable characters. A human-readable version of the License key data is also provided for reference and is included inside a Comment block in the final string that is copied to the Clipboard. For example, if an object uses the string "Copyright (c) 1994" (without the quotes) for its License key, LicReqst would generate the following block of text that could be copied to and pasted from the Clipboard: /* Copyright (c) 1994 */ WCHAR pwchLicenseKey[] = { 0x0043, 0x006F, 0x0070, 0x0079, 0x0072, 0x0069, 0x0067, 0x0068, 0x0074, 0x0020, 0x0028, 0x0063, 0x0029, 0x0020, 0x0031, 0x0039, 0x0039, 0x0034, 0x0020 }; You can use the previous block of text in code that creates an instance of the Licensed object, and you can use the pwchLicenseKey variable to specify the object"s License key. For example, if MFC code is dynamically creating an instance of a Licensed ActiveX Control using the Create method of a Visual C++ Component Gallery generated wrapper class, the pwchLicenseKey variable can be used in the Create call like this: BSTR bstrLicense = ::SysAllocStringLen(pwchLicenseKey, sizeof(pwchLicenseKey)/sizeof(WCHAR)); m_MyControl.Create(NULL, WS_VISIBLE, CRect(10,10,10,10), this, 2, NULL, FALSE, bstrLicense); ::SysFreeString(bstrLicense); Note how a BSTR is created from the pwchLicenseKey variable and how the BSTR is then used for the License key parameter in the Create call. NOTE: The code in this sample that generates the text copied to the Clipboard makes the assumption that it is being executed on a little endian system (Intel x86-class processors). Because of this, it will not work correctly on big endian system. For these systems, it is still possible to use the Helper function used internally by the sample to request the License key from an object. The sample uses a Helper function called RequestLicenseKey() to get the License key from an object based on its ProgID. The source code for the RequestLicenseKey() function is shown later in the Sample Code section. To find other locations of interest in the sample source code, use the Find in Files feature of the Visual C++ Developer Studio to search for the string named SAMPLE CODE. This string has been used to tag each of the modified sections in the source code. NOTE: Running the LicReqst sample on a licensed machine to obtain an object"s License key, and then distributing that key to allow applications to be developed on other non-licensed machines, may be a violation of established copyrights. For more information and to determine if an object"s License key can be legally redistributed, refer to the License Agreement provided with the object or contact the creator of the object.

Adaptation is the evolution of a concept, it is as a point of view quotation with study, there is a language adaptation. Embarks from the adaptation, language use is seen as a caller and the constant process of choice. D Saul Aaron in his book Understanding of Pragmatic emphasis on all language use and language comprehension is to comply with the constant process of choice. Choose both occur in the structure of language level, also at the strategy level. Selection is the process of context and language selection both the dynamic process of mutual adaptation in the process, the language user"s consciousness in the communication process is highlighted by language choice.The whole selection process by the communicator"s subjective consciousness, language is the restriction of internal factors, sometimes is a kind of since ?

由于每个类型的飞机展示了其特定的空气动力学和操控特性，所以改变这些对不同类型的飞机模拟的特性是可取的。一种解决方案是把飞机的稳定系数，惯性系数，机身规格的空气动力模型为基础——这些在大多数气动稳定性和控制的教科书中都是可行的。但是，为新一代战斗机建模型时必须注意。为了提高可操作性，这些飞机设计了空气动力学的空档中性已达到不稳定。其稳定系数反映了这一不稳定性。

方法一：getconf LONG_BIT在linux终端输入getconf LONG_BIT命令如果是32位机器，则结果为32Linux代码 [root@localhost ~]# getconf LONG_BIT 32 如果是64位机器，则结果为64Linux代码 [root@localhost ~]# getconf LONG_BIT 64 方法二：uname -a如果是64位机器，会输出x86_64Linux代码 [chenzhou@testweb01 ~]$ uname -a Linux testweb01 2.6.18-308.4.1.el5 #1 SMP Tue Apr 17 17:08:00 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux 可以看到，uname-a执行后的结果中输出了x86_64，说明该机器是64位的，否则代表该机器是32位的Linux代码 [root@localhost ~]# uname -a Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux 方法三：file /sbin/init 或者 file /bin/ls示例：32位机器file /sbin/initLinux代码 [root@localhost ~]# file /sbin/init /sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped file /bin/lsLinux代码 [root@localhost ~]# file /bin/ls /bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped 示例：64位机器file /sbin/initLinux代码 [~]$ file /sbin/init /sbin/init: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped file /bin/lsLinux代码 [~]$ file /bin/ls /bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped 可以通过命令结果中的64-bit或者32-bit来判断该机器是64位还是32位
