db2 sysibm.sysroutines表查的都是什么

即创建db2数据库的时候,会创建一些系统表。这些表记录了所有数据库的对象(表、视图等),它们都在模式sysibm下面,并且均以sys开头,如systables、sysviews、sysindexes等,同时也为这些表建立了相应的视图,这些视图在模式syscat下面。官方说法如下:sysibm系统数据字典表(基本表)。syscat系统视图。简单讲:系统相关数据都放在sysibm表里面,syscat是基于sysibm的一组视图,一般来讲建议访问syscat看相关系统数据。系统数据是相对于你的应用数据而言的,比如表的定义之类的都在里面,但是你的业务数据都在你自己生成的表里面,当然你也不会用这些个系统schema。

MySQL中information_schema是什么_MySQL

bitsCN.com 大家在安装或使用MYSQL时,会发现除了自己安装的数据库以外,还有一个information_schema数据库。 information_schema数据库是做什么用的呢,使用WordPress博客的朋友可能会想,是不是安装模板添加的数据库呀?看完本片文章 后,你就会对information_schema数据库有所了解。information_schema数据库是MySQL自带的,它提供了访问数据库元数据的方式。什么是元数据呢?元数据是关于数据的数据,如数据库名或表名,列的数据类型,或访问权限等。有些时候用于表述该信息的其他术语包括“数据词典”和“系统目录”。在MySQL中,把 information_schema 看作是一个数据库,确切说是信息数据库。其中保存着关于MySQL服务器所维护的所有其他数据库的信息。如数据库名,数据库的表,表栏的数据类型与访问权 限等。在INFORMATION_SCHEMA中,有数个只读表。它们实际上是视图,而不是基本表,因此,你将无法看到与之相关的任何文件。information_schema数据库表说明:SCHEMATA表:提供了当前mysql实例中所有数据库的信息。是show databases的结果取之此表。TABLES表:提供了关于数据库中的表的信息(包括视图)。详细表述了某个表属于哪个schema,表类型,表引擎,创建时间等信息。是show tables from schemaname的结果取之此表。COLUMNS表:提供了表中的列信息。详细表述了某张表的所有列以及每个列的信息。是show columns from schemaname.tablename的结果取之此表。STATISTICS表:提供了关于表索引的信息。是show index from schemaname.tablename的结果取之此表。USER_PRIVILEGES(用户权限)表:给出了关于全程权限的信息。该信息源自mysql.user授权表。是非标准表。SCHEMA_PRIVILEGES(方案权限)表:给出了关于方案(数据库)权限的信息。该信息来自mysql.db授权表。是非标准表。TABLE_PRIVILEGES(表权限)表:给出了关于表权限的信息。该信息源自mysql.tables_priv授权表。是非标准表。COLUMN_PRIVILEGES(列权限)表:给出了关于列权限的信息。该信息源自mysql.columns_priv授权表。是非标准表。CHARACTER_SETS(字符集)表:提供了mysql实例可用字符集的信息。是SHOW CHARACTER SET结果集取之此表。COLLATIONS表:提供了关于各字符集的对照信息。COLLATION_CHARACTER_SET_APPLICABILITY表:指明了可用于校对的字符集。这些列等效于SHOW COLLATION的前两个显示字段。TABLE_CONSTRAINTS表:描述了存在约束的表。以及表的约束类型。KEY_COLUMN_USAGE表:描述了具有约束的键列。ROUTINES表:提供了关于存储子程序(存储程序和函数)的信息。此时,ROUTINES表不包含自定义函数(UDF)。名为“mysql.proc name”的列指明了对应于INFORMATION_SCHEMA.ROUTINES表的mysql.proc表列。VIEWS表:给出了关于数据库中的视图的信息。需要有show views权限,否则无法查看视图信息。TRIGGERS表:提供了关于触发程序的信息。必须有super权限才能查看该表 bitsCN.com

Go中的特殊协程g0

【译文】 原文地址 本文基于go 1.13版本 所有在Go中创建的goroutines都由一个内部调度程序的管理。Go调度程序试图给所有的goroutines分配运行时间,并且在当前goroutine被阻塞或终止情况下也能使CPU忙于运行其他goroutines。 Go通过GOMAXPROCS变量来限制操作系统线程同时运行的数量。这意味着,Go必须在每个正在运行的线程上调度和管理所有的goroutines。这个角色通过一个特殊的goroutine来完成,称为g0,这是为每个操作系统线程创建的第一个goroutine:当goroutine被阻塞在channel上时,当前的goroutine就会被挂起,即处于等待模式将不会推入任何goroutines队列中。收到消息的goroutine将切换到g0,然后将挂起的goroutine放入到本地调度队列中: 尽管g0这个特殊goroutine是管理调度的,但是它不止这些工作还有其他更多的功能。 与普通goroutine相反,g0有固定且比较大的栈。这允许Go在需要更大栈时,还能执行操作。g0的职责可以如下:

求一篇英语作文:Life is never short of beauty

Life is never short of beautyOur life is never short of beauty . what matters is that we should search for the beauty through our eyes of our own accord. If you keep an eye open for things around us intentional , you can find that there are much more beauty than you image . In the nature , the scene of sunrise or sunset is usually thought of as a beautiful moment, for it brings people brightness and warmth and it indicates hope and a new beginning. You may feel refreshed, inspired and full of energy when watching such a scene. And Life is mostly made up of routines and patterns. Every day we act them out and they are what make up the bulk of our lives. Many of us live according to a socially acceptable template, within the realm of safety, while living repetitively and dreaming of ways to escape.I used to revolt against these routines. I saw them as the enemy of adventure and of living a spontaneous life. However, I"ve found that routines can be quite blissful. I"ve realized that every day events and what we would commonly classify as “normal”, is often extraordinary if you just take a closer look.I"ve discovered that even if you"re not exactly where you"d like to be, that doesn"t mean that life right now can"t be beautiful or enjoyable. And the best part is, you don"t have to do anything to make it beautiful. It already is beautiful.All you have to do is open your eyes.

大学英语作文:生活的意义 The Meaning of Life

【 #英语资源# 导语】学习英语,阅读真的很重要,多阅读一些短篇英语文章也是提高英语阅读能力的一种。下面是 !   【篇一】生活的意义 The Meaning of LifeSince we were born, we are meant to face the stage of study and work until we retire, which seems everybody does the same thing in their life. They start to wonder about the meaning of life. In my opinion, the meaning of life lies in study and finding the right place. 自打我们出生起,就注定要经历学习和工作的阶段,直到退休,似乎每个人在他们的一生中都在做着一样的事。他们开始思考人生的意义,在我看来,生命的意义在于学习并找到人生定位。 Study comes first for human being. Since we learn the knowledge, we get to know about the world. The more we learn, the more we want to search for the unknown knowledge. The world is beautiful because of diversity, and there are so many amazing scenery waiting for us to discover. At the process of searching the knowledge, we also become mature and have our own thinking. 对于我们来说学习是最重要的。我们学习了知识就对世界开始有了一定的了解。我们学得越多,就越想寻求未知的知识。因其多样性,世界是美丽的,有很多令人惊叹的风景在等着我们去发现。在寻找知识的过程中,我们也变得成熟,有自己的想法。 Finding the place in the world is the basic task for us. The purpose of knowledge is to master some skills, so as to get accustomed to the world and know what we want to do and what we can bring to the world. The value we create can bring happiness to people we love and make a contribution to the world. 找准自己的在世界上的位置是我们的基本任务。知识的目的是掌握技能,来适应这个世界,知道我们想做什么,可以给世界带来什么。我们创造的价值可以给我们爱的人带来快乐,给世界做出贡献。 Life is short, but we keep searching all the time. 生命是短暂的,但是我们会不断探索。   【篇二】减肥误区 The Wrong Ways to Lose Weight For every girl, they chase to look beautiful all the time, even some of them take it as the lifetime career. What"s more, the commercial ads implant them the idea that only skinny girls can be charming, so some girls take the extreme ways to lose weight, which hurts their bodies badly. 对于每一个女孩来说,她们时刻追逐,甚至有些人把它当作一生的事业。而且,商业广告也灌输了她们这样的想法,只有纤瘦的女孩才有魅力,所以有些女孩们采取极端的方法减肥,这严重伤害了她们的身体。 The most common wrong way to lose weight is to refuse food. Most girls believe that if they bear the hunger, then their bodies will not grow fat, so they just eat little food and fight with food temptation. It is not worthy of hurting bodies to lose weight. If we don"t keep healthy, we may lose our lives. The suitable way is to go on a diet with doctor"s professional advice. 最常见的错误减肥方法是不吃东西。大多数女孩相信如果她们能够忍受饥饿,她们就不会发胖,所以她们只吃很少的食物,与食物的诱惑做抗争。伤害身体的减肥是不值得的。如果我们不保持健康,就有可能会失去生命。恰当的方法是听从医生的专业建议去进行节食。 The second wrong way is to take pills. Many commercial ads try to attract more females to buy the products, so they brag about the effect of taking pills. Actually, these pills have side effects, which damage the bodies. Many experts have told the truth that taking regular exercise is the best way to keep fit. 第二个错误的方法是吃药。许多商业广告试图通过吹嘘服药效果来吸引更多的女性去购买他们的产品。实际上,这些药有副作用,会损害身体。许多专家已经指出经常锻炼是保持健康的方法。 It is everybody"s right to chase looking beautiful, but they must do the wise things. 每个人都有权利去追逐美丽,但他们必须做明智的事情。   【篇三】如何应对负面情绪 How to Deal With Negative EmotionLife is a journey. We will see different scenery and learn to grow up. Nobody can live easy life all the time, and they must have gone through some hard time. The one who can conquer the difficulty will be stronger. While those who can"t deal with the negative emotion will miss the beautiful scenery. Wise men can find the ways to remove bad mood. 生活是一场旅程,我们将会看到不一样的风景并学习成长。没有人能一直过着一帆风顺的生活,他们都会经历一些艰难的时刻。那些能够克服困难的人会变得更强。而那些不能处理负面情绪的人会错过美丽的风景。智者总能找到方法来消除坏心情。 In the modern life, a lot of people do the same things every day, then the repeating routines are easy to frustrate them. They feel life is meaningful and why they have to sit in the office to work for a whole day. The negative emotion makes them lose themselves. At this time, they need to slow down their life pace. A trip is the best way to relax and forget about the annoyance. It opens your vision and helps you to find the answers. 在现代生活中,很多人每天都在做同样的事情,重复着日常,很容易有挫败感。他们觉得生活是有意义的,但是他们却要坐在办公室里工作一整天。消极情绪使他们迷失自我。在这个时候,他们需要放慢生活节奏。旅行是的放松方式,可以忘记烦恼。它也开阔了你的视野,帮助你找到答案。 Talking to the families or friends is also a good way to relieve your bad emotion. We need someone to listen to us. With their support and caring, we will find the motivation to move on. Life is short, don"t be afraid of making change if you are not really satisfied with the current situation. 跟家人或朋友倾诉也是缓解负面情绪的一个好办法。我们需要有人倾听我们。有了他们的支持和关爱,我们就会找到继续前进的动力。人生短暂,如果你不满意当前的局势,不要害怕改变。

萤光灯工作原理 萤光灯功率

萤光灯工作原理是什么呢?萤光灯功率都是多少呢?萤光灯在安装的时候注意事项是什么呢?一起来具体的看看吧~ 萤光灯工作原理 萤光灯分传统型萤光灯和无极萤光灯,传统型萤光灯即低压汞灯,是利用低气压的汞蒸气在放电过程中辐射紫外线,从而使萤光粉发出可见光的原理发光,因此它属于低气压弧光放电光源。 萤光灯的主要元件是密封玻璃管。管中含有少量的汞和惰性气体,通常是氩气,这些气体保持在低压下。管中还含有磷粉,涂在玻璃内壁上。灯管的每一端都有一个与电路相连的电极。 当打开灯的时候,电流就沿着电路流到电极。电极之间就会有很大的电压,于是,电子就会通过气体从灯管的一端游离到另一端。而能量使灯管中的汞从液态转化为气态。在穿过灯管的过程中,电子和一部分带电原子将与气态汞原子碰撞。这些碰撞将激发原子,使电子跃迁到更高的能级上。当电子返回它们的初始能级时,就会释放光子。 光子的波长是由原子中的特定电子排布决定的。由于汞原子中的电子排布方式,它们释放的光子大部分都在紫外线波长范围内。而我们的眼睛感觉不到紫外线的光亮, 所以,要让灯管发亮,就需要把这种光转化成可见光。 灯管上涂的磷粉就发挥着这种作用。磷是暴露在光下会发光的物质。当光子撞击磷原子的时候,磷的电子就会跃迁到一个较高的能级,从而原子会变热。当电子跃迁回它的常态能级时候,它就会以另一种光子的形式释放能量。因为一些能量以热的形式散失了,所以这种光子的能量比起始光子的低。在萤光灯中发射的光属于可见光谱——磷发出我们可以看见的白光。生产厂家可以通过使用磷的不同混合,改变光的颜色。 萤光灯功率 目前市面上常见的萤光灯有直管形萤光灯、彩色直管型萤光灯、环形萤光灯、单端紧凑型节能萤光灯四类。我们主要介绍一下最后的节能型萤光灯的功率。 节能萤光灯功率有:5w、7w、9w、11w、13w、18w、36w、45w、65w、85w、105w这几种。 萤光灯安装注意事项 1、灯具应安装通风良好、少粉尘、周围无腐蚀性气体及可燃易爆物品的室内外场所。电源电压允许在额定电压的+20%至-20%范围内波动,超出范围会影响点灯技术参数, 过高电压可能烧毁电子镇流器。 2、不同型号的无极萤光灯灯泡只能与其相匹配的同功率电子镇流器配合使用。 3、连接灯泡的电缆线不可随意加长。 4、对于北方等冬季较寒冷的地区或在户外使用的场所,所采用的灯具应当采用密封等级高的, 严禁将配用的灯具面盖拆卸使用。 5、配套灯具实际系统功率偏差在±10%范围内均属于允许范围。 6、在安装萤光灯灯具时应首先认真阅读灯具使用说明书,了解灯具的安装固定方式,以便预先做好相应的配套安装措施。 7、在安装灯具前,最好能先将灯具连接好先通电确认灯具会亮后再将灯具安装上。以防安装后因运输或其他原因导致灯不亮后再检查所带来的麻烦。 8、高挂灯具(GC系列)灯罩所配用的钢圈上下两边的宽度不一样, 9、安装时应将宽的一面紧扣住出光面罩一边,窄的一面扣住灯罩。

ufeff萤光灯的发光原理解析

荷兰飞利浦首先研制成功了将能够发出人眼敏感的红、绿、蓝三色光的萤光粉。三基色萤光粉的开发与应用是萤光灯发展史上的一个重要里程碑。下面我们一起来看看萤光灯的发光原理是什么吧。 萤光灯的发光原理解析 从萤光灯的发光机制可见,萤光粉对萤光灯的质量起关键作用。萤光灯属于气体放电光源,气体放电光源的伏安特性。曲线上的A~D为非自持放电微光区;D~E为过渡区;E~F为正常辉光放电区,如霓虹灯;F~G为异常辉光放电区;G~K为正常弧光放电区,如日光灼。 霓虹灯是辉光放电,萤光灯是弧光放电。在萤光灯的点亮或电弧燃烧前,它具有很高的输入阻抗,因为此时基本上没有导电离子:这样高压Uns就会加在灯管上,这是点亮灯管的额定启动电压。在正常工作之后,加在灯管上的电压就会下降为工作电压Uop那么灯的工作电流就由xb(在工作频率下镇流器的阻抗)及下式得出。 公式式中的电压和电流指的是有效值,因而可以得出灯管所消耗的功率为:Pi=UopIop 灯管在50°F时的额定启动电压由厂商给出,但是为了确保灯管在最坏的情况下也能点亮,实际的启动电压至少要加大厂商给定值的10%。美国国家标准机构(ANSI)在萤光灯的规范中指定了不同类型灯管的Uop和Iop值,这样厂商在制作时必须满足灯管的最大功率定额。 萤光灯的发光原理解析 从ANSI规范可以得出所选类型灯管的Uop和Iop值,再从厂商那里得到所要的Uns值,就可以从上式确定出镇流器的阻抗xb。而在电子镇流器里这个阻抗的值是由电容确定的,它可以由下式求得公式2,式中的CbT是指与灯管串联的等效电容,因为灯管可能是由连接起来的两个电容驱动的。 通过选择不同阻抗的电容, 萤光灯可以使灯管在高于或低于该型号的额定功率下工作,也就是灯管可以在任意给定的功率下运行,包括极限值,这通过Uop和Iop的任意组合来实现。这样在任意的功率水平下,可以任意规定Iop并通过第一式计算Uop则电子镇流器的阻抗可以通过第一上式得出,电容值可以通过第二式得出。 虽然任何萤光灯都可以在此ANSI规范规定的该类型萤光灯额定功率更高的功率下工作,但是它的寿命会明显下降。灯管即使在规定的功率下工作,它的寿命也会小于预计的时间,这是因为预计的时间是厂商在一定的电流电压和温度环境下测试出来的。以上就是这次给大家带来的信息了,希望大家能够喜欢我们的资讯。

荧光灯工作原理及其相关介绍

  “荧光灯”它可以分为传统型荧光灯和无极荧光灯,荧光灯的使用寿命比较长,同时它的显色性和光效都比较好,荧光灯的使用范围也比较广,那么接下来小编为大家介绍一下荧光灯的工作原理和其他的介绍,希望可以帮助到大家。  第一点:荧光灯的工作原理  首先荧光灯的内壁涂有荧光粉,同时它的管理还充有400帕到500帕的氩气和少量的一些汞,在通电的情况下,管内的汞原子受到了激发作用,从而辐射出紫外线,可以放出多余的能量,这样管内的荧光粉就可以吸收紫外线的辐射从而就可以发出光了。另外,荧光粉的颜色不同,所折射出来的光线也就不同,荧光灯所消耗的电能大部分运用在了产生紫外线上,所以荧光灯属于一种节能光源。  第二点:荧光灯的保养维修  首先,在使用荧光灯的时候一定不要过于频繁地开关灯。这是因为如果过于频繁的开关单则会导致灯管的两端变黑,从而影响灯光的亮度。另外在使用荧光灯的时候也一定要给它保持一个比较通风的环境,这样做的原因一是可以带走灰尘,二是可以降低灯管的温度,从而增强荧光灯的使用寿命。第三点,在安装荧光灯的时候需要很多线路,这时候就需要一些辅助器件,比如说变压器,这样也可以增加荧光灯的使用寿命,同时也能使荧光单达到一个适合的功率。  第三点:荧光灯的常见问题及其维修方法  在使用荧光灯的时候经常会遇到灯管不发光的现象,这时我们第一步需要检查电源是否接通,如果接通的话,接下来还需要检测灯管的单丝是否被烧坏,如果被烧坏的话,则需要更换新的荧光灯,如果没有烧坏的话,接下来我们还需要检测一下灯具接插件是否接触不良,镇流器是否被损坏,如果是的话则需要重新安装这些零件,如果不是的话则需要继续检测它的灯管是否漏气,如果是的话则需要更换新的灯管。  关于荧光灯的工作原理及其其他相关介绍,小编就先简单的为大家说到这里,大家在使用荧光灯的时候,一定要注意小编说的保养和维修方法。注意到这些,可以保证荧光灯的使用寿命。土巴兔在线免费为大家提供“各家装修报价、1-4家本地装修公司、3套装修设计方案”,还有装修避坑攻略!点击此链接:【https://www.to8to.com/yezhu/zxbj-cszy.php?to8to_from=seo_zhidao_m_jiare&wb】,就能免费领取哦~
