感恩节

每年11月第四周的星期四被定为感恩节。感恩节原本是美国和加拿大的传统节日，用来纪念最初移民美洲的困苦岁月和与印第安人的友好关系。 　　1620年，102名英国清教徒乘坐”五月花号“来到美洲。在刚刚抵达美洲，英国移民者们遇到了许多艰难困阻，经过一个冬季的饥寒交迫，让最初的102名移民只剩下了50余人。正当英国移民困苦难当时，热情好客的印第安人对他们伸出了援手，帮助移动者们顺利地在美洲大陆安定了下来。感恩节就是从印第安人庆祝丰收，感谢上天恩赐的日子演变而来，慢慢成了当今感念当初困苦岁月，怀念与印第安人的友好关系的节日。

Thanksgiving 感恩 节、的英语作文 The Pilgrims who sailed to this country aboard the Mayflower were originally members of the English Separatist Church (a Puritan sect). They had earlier fled their home in England and sailed to Holland (The Netherlands) to escape religious persecution. There, they enjoyed more religious tolerance, but they eventually became disenchanted with the Dutch way of life, thinking it ungodly. Seeking a better life, the Separatists negotiated with a London stock pany to finance a pilgrimage to America. Most of those making the trip aboard the Mayflower were non-Separatists, but were hired to protect the pany"s interests. Only about one-third of the original colonists were Separatists. The Pilgrims set ground at Plymouth Rock on December 11, 1620. Their first winter was devastating. At the beginning of the following fall, they had lost 46 of the original 102 who sailed on the Mayflower. But the harvest of 1621 was a bountiful one. And the remaining colonists decided to celebrate with a feast -- including 91 Indians who had helped the Pilgrims survive their first year. It is believed that the Pilgrims would not have made it through the year without the help of the natives. The feast was more of a traditional English harvest festival than a true "thanksgiving" observance. It lasted three days. 8. 感恩节ThanksgivingDay英语作文 Thanksgiving Day is one of the most important festivals in America. It s most closely connected to the earliest history of the country.

感恩节的介绍英文版 　　感恩节是美国和加拿大共有的节日，由美国人民独创，原意是为了感谢上天赐予的好收成、感谢印第安人的帮助，下面是我整理的关于感恩节英文版的介绍，欢迎大家阅读了解! 　　感恩节的介绍(英文版) 　　now i would like to give you some details about thanksgiving day in the united states. thanksgiving day is the most truly american of the national holidays in the united states and is most closely connected with the earliest history of the country. 　　in 1620, the settlers, or pilgrims, they sailed to america on the may flower, seeking a place where they could have freedom of worship. after a tempestuous two-month voyage they landed at in icy november, what is now plymouth, massachusetts. 　　during their first winter, over half of the settlers died of starvation or epidemics. those who survived began sowing in the first spring. 　　all summer long they waited for the harvests with great anxiety, knowing that their lives and the future existence of the colony depended on the coming harvest.finally the fields produced a yield rich beyond expectations. and therefore it was decided that a day of thanksgiving to the lord be fixed. years later, president of the united states proclaimed the fourth thursday of november as thanksgiving day every year. the celebration of thanksgiving day has been observed on that date until today. 　　the pattern of the thanksgiving celebration has never changed through the years. the big family dinner is planned months ahead. on the dinner table, people will find apples, oranges, chestnuts, walnuts and grapes.there will be plum pudding, mince pie, other varieties of food and cranberry juice and squash. the best and most attractive among them are roast turkey and pumpkin pie. they have been the most traditional and favorite food on thanksgiving day throughout the years. 　　everyone agrees the dinner must be built around roast turkey stuffed with a bread dressing to absorb the tasty juices as it roasts. but as cooking varies with families and with the regions where one lives, it is not easy to get a consensus on the precise kind of stuffing for the royal bird.thanksgiving today is, in every sense, a national annual holiday on which americans of all faiths and backgrounds join in to express their thanks for the year" s bounty and reverently ask for continued blessings. 　　现在我想给你们详细谈谈美国的感恩节。感恩节是美国国定假日中最地道、最美国式的节日，而且它和早期美国历史最为密切相关。 　　1620年，一些朝圣者(或称为清教徒)乘坐"五月花"号船去美国寻求宗教自由。他们在海上颠簸折腾了两个月之后，终于在酷寒的十一月里，在现在的马萨诸塞州的普里茅斯登陆。 　　在第一个冬天，半数以上的移民都死于饥饿和传染病，活下来的人们在第一个春季开始播种。整个夏天他们都热切地盼望着丰收的`到来，他们深知自己的生存以及殖民地的存在与否都将取决于即将到来的收成。 　　后来，庄稼获得了意外的丰收，所以大家决定要选一个日子来感谢上帝的恩典。多年以后，美国总统宣布每年十一月的第四个星期四为感恩节。感恩节庆祝活动便定在这一天，直到如今。 　　感恩节庆祝模式许多年来从未改变。丰盛的家宴早在几个月之前就开始着手准备。人们在餐桌上可以吃到苹果、桔子、栗子、胡桃和葡萄，还有葡萄干布丁、碎肉馅饼、各种其它食物以及红莓苔汁和鲜果汁，其中最妙和最吸引人的大菜是烤火鸡和番瓜馅饼，这些菜一直是感恩节中最富于传统意义和最受人喜爱的食品。 　　人人都赞成感恩节大餐必需以烤火鸡为主菜。火鸡在烘烤时要以面包作填料以吸收从中流出来的美味汁液，但烹饪技艺常因家庭和地区的不同而各异，应用什幺填料也就很难求得一致。 　　今天的感恩节是一个不折不扣的国定假日。在这一天，具有各种信仰和各种背景的美国人，共同为他们一年来所受到的上苍的恩典表示感谢，虔诚地祈求上帝继续赐福。 ;

感恩节的由来可以追溯到1621年的美国普利茅斯殖民地。当时，殖民者们与当地的印第安人共同庆祝他们第一次成功丰收的收获。这场盛宴持续了三天，人们一起唱歌跳舞，庆祝他们的成功。总之，感恩节是一个值得我们庆祝和感恩的节日。在这一天，让我们一起庆祝我们的丰收，感恩我们所拥有的一切，并且希望未来的日子里，我们都能够保持感恩的心态，更加珍惜生命中的每一刻。感恩节的意义不仅仅是庆祝丰收，更重要的是感恩。人们可以感恩自己所拥有的一切，无论是家人、朋友、健康、工作、爱情还是生命本身。感恩是一种积极向上的情感，可以让我们更加珍惜生命中的每一刻，更加努力地追求自己的梦想。感恩节的意义不仅仅是庆祝丰收，更重要的是感恩。人们可以感恩自己所拥有的一切，无论是家人、朋友、健康、工作、爱情还是生命本身。感恩是一种积极向上的情感，可以让我们更加珍惜生命中的每一刻，更加努力地追求自己的梦想。

Thanksgiving Day(感恩节) In the United States, the fourth Thursday in November is called Thanksgiving Day. On that day, Americans give thanks for the blessings they have enjoyed during the year.Thanksgiving Day is usually a family day. People always celebrate with big dinners and happy reunions. Pumpkin pie and Indian pudding are traditional Thanksgiving desserts. Relatives from other cities, students who have been away at school, and many other Americans travel a long distance to spend the holiday at home.

EDI文档由遵循特定的EDI标准格式规范的数据元素（data elements）、段 (segments) 和 信封 (envelopes) 构成。EDI标准的规则准确定义了信息在文档中的位置，以及查找信息的方式。因此，在创建EDI文档时（如，采购订单），必须严格按照EDI标准（ANSI/EDIFACT）的格式规范。这样，当接收方的EDI翻译器读取到传入的EDI采购订单时，就能准确地找到买方公司名称、采购订单号、订购商品以及价格等信息。之后，这些数据将按照接收方系统的格式，直接传入其订单录入系统。以下列采购订单为例，将其转换为ANSI标准和EDIFACT标准的两个EDI文档：按照EDI标准，如采购订单、发货单、提前装船通知，称为“事务集”或“消息”，由数据元素、段和信封构成。数据元素(Data Elements): EDI事务集中独立的信息单元例如，在许多EDI文档形式的采购订单或是发货单中你会看到，如城市、州、国家、品号、数量和价格等这样的数据元素。 数据元素被区分为数字型、文本型和日期型，其定义包含：数据类型 – 数字型、字母型、日期型或时间型最小长度/最大长度可用的代码值一定对应某个数据类型，例如，数据元素是单价，可以用货币符号表示美元、欧元等不同货币类型数据元素(Data Elements)构成段(Segments)段(Segments): 一组相关的数据元素填写采购订单信息时,一定期望看到相关的数据能以组划分，但是，通常情况下，纸质样式的采购订单是以一个整体展现的。 请注意，以下订单被划分成四部分后，每部分都传达了不同的信息：EDI文档的每个部分都用一个特定的段描述，以下是依照ANSI标准，用一组段(segments)对上述采购订单进行了描述，每个段都用ST，BEG，N1之类的段识别符开始，指明随从的数据元素的类型，段中的数据元素之间用 “*”符号分隔。对于任意类型的商业文档，EDI标准文档定义:片段中可能包含的必选的、可选的或是有条件约束的元素每个段可能包含纸质文档中相应的EDI元素，这些元素被定义在标准规范字典里，同样的，每条标准都有相应的字典必要的片段和元素序列片段重复的次数现在,一旦所有的段被收集到一个指定的队列,就形成了一个完整的事务集。之后，事务集被装进信封发送给伙伴。信封（Envelopes）EDI文档传输需要使用三个“信封”存放事务集，分别是事务集信封（消息信封）、组信封和交互信封。我们平时可以用一个信封传送多个纸质商业文档，但是，EDI文档交换需要使用多个信封。每个事务集放在独立的事务集信封中一组事务集（如，一个订单）放在一个组信封中（组信封对于ANSI标准是必须有的，对于EDIFACT标准是可选的）所有的组信封都放置在交互信封中，由发送方传送至接收方如下图所示：在适当的部分，会用一对段标识来指明信封的起始和终止位置。以EDIFACT标准为例，用UNH和UNT段标识指明事务组信封，用UNG和UNE段标识指明组信封，用UNA/B和UNZ段标识指明交互信封。通常情况下，用“S”标注开始，用“E”标注结束。下图以采购订单为例，对事务集信封（消息信封）、组信封和交互信封这三个层次进行了说明。本文由知行软件原创，请尊重原创内容，如需转载本文章，请注明文章原始地址。

本文中的数据平台已迭代三个版本，从头开始遇到很多常见的难题，终于有片段时间整理一些已完善的文档，在此分享以供所需朋友的。实现参考，少走些弯路，在此篇幅中偏重于ES的优化，目前生产已存储百亿数据，性能良好，关于HBase，Hadoop的设计优化估计有很多文章可以参考，不再赘述。 项目背景：在一业务系统中，部分表每天的数据量过亿，已按天分表，但业务上受限于按天查询，并且DB中只能保留3个月的数据(硬件高配)，分库代价较高。 改进版本目标： 谈到优化必须能了解组件的基本原理，才容易找到瓶颈所在，以免走多种弯路，先从ES的基础结构说起(如下图)： 一些基本概念: ES依赖一个重要的组件Lucene，关于数据结构的优化通常来说是对Lucene的优化，它是集群的一个存储于检索工作单元，结构如下图： 在Lucene中，分为索引(录入)与检索(查询)两部分，索引部分包含 分词器、过滤器、字符映射器 等，检索部分包含 查询解析器 等。一个Lucene索引包含多个segments，一个segment包含多个文档，每个文档包含多个字段，每个字段经过分词后形成一个或多个term。 通过Luke工具查看ES的lucene文件如下，主要增加了_id 和 _source字段: Lucene 索引文件结构主要的分为：词典、倒排表、正向文件、DocValues等，如下图: Lucene 随机三次磁盘读取比较耗时。其中.fdt文件保存数据值损耗空间大，.tim和.doc则需要SSD存储提高随机读写性能。 另外一个比较消耗性能的是打分流程，不需要则可屏蔽。 关于DocValues： 倒排索引解决从词快速检索到相应文档ID, 但如果需要对结果进行排序、分组、聚合等操作的时候则需要根据文档ID快速找到对应的值。 通过倒排索引代价缺很高：需迭代索引里的每个词项并收集文档的列里面 token。这很慢而且难以扩展：随着词项和文档的数量增加，执行时间也会增加。Solr docs对此的解释如下： 在lucene 4.0版本前通过FieldCache，原理是通过按列逆转倒排表将（field value ->doc）映射变成（doc -> field value）映射，问题为逐步构建时间长并且消耗大量内存，容易造成OOM。 DocValues是一种列存储结构，能快速通过文档ID找到相关需要排序的字段。在ES中，默认开启所有(除了标记需analyzed的字符串字段)字段的doc values，如果不需要对此字段做任何排序等工作，则可关闭以减少资源消耗。 ES中一个索引由一个或多个lucene索引构成，一个lucene索引由一个或多个segment构成，其中segment是最小的检索域。 数据具体被存储到哪个分片上：shard = hash(routing) % number_of_primary_shards 默认情况下 routing参数是文档ID (murmurhash3),可通过 URL中的 _routing 参数指定数据分布在同一个分片中，index和search的时候都需要一致才能找到数据，如果能明确根据_routing进行数据分区，则可减少分片的检索工作，以提高性能。 在我们的案例中，查询字段都是固定的，不提供全文检索功能，这也是几十亿数据能秒级返回的一个大前提： 1、ES仅提供字段的检索，仅存储HBase的Rowkey不存储实际数据。 2、实际数据存储在HBase中，通过Rowkey查询，如下图。 3、提高索引与检索的性能建议，可参考官方文档（如 https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-indexing-speed.html ）。 一些细节优化项官方与其他的一些文章都有描述，在此文章中仅提出一些本案例的重点优化项。 1、批量写入，看每条数据量的大小，一般都是几百到几千。 2、多线程写入，写入线程数一般和机器数相当，可以配多种情况，在测试环境通过Kibana观察性能曲线。 3、增加segments的刷新时间，通过上面的原理知道，segment作为一个最小的检索单元，比如segment有50个，目的需要查10条数据，但需要从50个segment，分别查询10条，共500条记录，再进行排序或者分数比较后，截取最前面的10条，丢弃490条。在我们的案例中将此 "refresh_interval": "-1" ，程序批量写入完成后进行手工刷新(调用相应的API即可)。 4、内存分配方面，很多文章已经提到，给系统50%的内存给Lucene做文件缓存，它任务很繁重，所以ES节点的内存需要比较多(比如每个节点能配置64G以上最好）。 5、磁盘方面配置SSD，机械盘做阵列RAID5 RAID10虽然看上去很快，但是随机IO还是SSD好。 6、 使用自动生成的ID，在我们的案例中使用自定义的KEY，也就是与HBase的ROW KEY，是为了能根据rowkey删除和更新数据，性能下降不是很明显。 7、关于段合并，合并在后台定期执行，比较大的segment需要很长时间才能完成，为了减少对其他操作的影响(如检索)，elasticsearch进行阈值限制，默认是20MB/s， 可配置的参数："indices.store.throttle.max_bytes_per_sec" : "200mb" （根据磁盘性能调整） 合并线程数默认是：Math.max(1, Math.min(4, Runtime.getRuntime().availableProcessors() / 2))，如果是机械磁盘，可以考虑设置为1：index.merge.scheduler.max_thread_count: 1， 在我们的案例中使用SSD，配置了6个合并线程。 1、关闭不需要字段的doc values。 2、尽量使用keyword替代一些long或者int之类，term查询总比range查询好 (参考lucene说明 http://lucene.apache.org/core/7_4_0/core/org/apache/lucene/index/PointValues.html )。 3、关闭不需要查询字段的 _ source 功能，不将此存储仅ES中，以节省磁盘空间。 4、评分消耗资源，如果不需要可使用filter过滤来达到关闭评分功能，score则为0，如果使用constantScoreQuery则score为1。 5、关于分页： （1）from + size: 每分片检索结果数最大为 from + size，假设from = 20, size = 20，则每个分片需要获取 20 x 20 = 400条数据，多个分片的结果在协调节点合并(假设请求的分配数为5，则结果数最大为 400 * 5 = 2000条) 再在内存中排序后然后20条给用户。这种机制导致越往后分页获取的代价越高，达到50000条将面临沉重的代价，默认from + size默认如下: index.max_result_window：10000 (2) search_after: 使用前一个分页记录的最后一条来检索下一个分页记录，在我们的案例中，首先使用from+size，检索出结果后再使用search_after，在页面上我们限制了用户只能跳5页，不能跳到最后一页。 (3) scroll 用于大结果集查询，缺陷是需要维护scroll_id 6、关于排序：我们增加一个long字段，它用于存储时间和ID的组合(通过移位即可)，正排与倒排性能相差不明显。 7、关于CPU消耗，检索时如果需要做排序则需要字段对比，消耗CPU比较大，如果有可能尽量分配16cores以上的CPU，具体看业务压力。 8、关于合并被标记删除的记录，我们设置为0表示在合并的时候一定删除被标记的记录，默认应该是大于10%才删除： "merge.policy.expunge_deletes_allowed": "0"。 优化效果评估基于基准测试，如果没有基准测试无法了解是否有性能提升，在这所有的变动前做一次测试会比较好。在我们的案例中： 1、单节点5千万到一亿的数据量测试，检查单点承受能力。 2、集群测试1亿-30亿的数量，磁盘IO/内存/CPU/网络IO消耗如何。 3、随机不同组合条件的检索，在各个数据量情况下表现如何。 4、另外SSD与机械盘在测试中性能差距如何。 性能的测试组合有很多，通常也很花时间，不过作为评测标准时间上的投入有必要，否则生产出现性能问题很难定位或不好改善。对于ES的性能研究花了不少时间，最多的关注点就是lucene的优化，能深入了解lucene原理对优化有很大的帮助。 目前平台稳定运行，百亿的数据查询100条都在3秒内返回，前后翻页很快，如果后续有性能瓶颈，可通过扩展节点分担数据压力。

手机pro这个是professional的缩写，翻译过来就是专业的意思，带有这个后缀的手机，说明这个手机有更加专业的特色功能。这个版本基本上是同一系列手机中最强的版本了，但是后面手机厂商又出了pro+，＋就是加强版，这个则代表比专业更专业，是目前手机中同系列手机的最强版本。简介一般手机、平板都会有标准版，标准版的意思是厂商发行的基本模版，所有的简化版本或扩展版本都是以此为基础。专业版是拓展版本，它的优势是比其原先版本存在更为广阔的功能，又或者是针对特定人群有针对性的专门设计。当然还有一些常见的命名型号，例如Plus，这个版本就是指的更加优越，版本更高的意思，常见于苹果系列的设备，当然一些厂家也在使用。
