rather和quite的区别

您好。07诺诺很高兴为您解答。不过诺诺偶想问您是需要用rather和quite来补充句子么?首先,诺诺会告诉您rather、quite的意思到底是什么,——rather,副词,相当,颇,有点儿、rather一般都常与or连接,使得能更确切的说明句子的含义。——quite,完全、彻底化。也可以作为相当、颇。那么如果不用用来填词——thisboyisverycleverbutislazy.当然,楼主如果需要的话——thisboyisquitecleverbutratherlazy.因为lazy,慵懒。那应该解释为,“但是更加慵懒”。很高兴为您解答,祝您愉快。

rather than的用法与搭配

短语rather than是一个并列连词,用法比较复杂。本文总结了其用法,供参考! 用法与搭配 一、rather than用作连词,连接两个平行结构.既可以表示主观愿望上的决择,“与其…宁可…”,也可以表示客观程度上的差异,“与其说是…不如说是…”.例如: 1、接代词 1)I,rather than you,should do the work. 该做这工作的是我,而不是你. 2、接名词 2)John ought to go rather than Jean.约翰比琴更应该去. 3)I think I"ll have a cold drink rather than coffee. 我想我该要一杯冷饮,而不要咖啡. 试比较: 4)We sometimes eat rice instead of potatoes. 有时候我们不吃土豆,而吃米饭. 3、接形容词 5)These shoes are comfortable rather than for your friend. 这鞋不好看可是舒服. 6)You are doing this for yourself rather than for your friend. 你不是为你朋友,而是为你自己做这种事. 7)I"d prefer to go in August rather than in July.我愿8月去不愿7月去. 5、接动名词 8)I always prefer starting early,rather than leaving everything to the last minute, 我总是愿意早开始而不愿意把所有事情都留到最后才做. 9)He was engaged in writing a letter rather than reading the newspaper. 他那时是在写信而不是看报纸. 6、接过去分词 10)She insisted on having the room papered rather than painted. 她坚持要用纸裱糊房间,而不是把房间粉刷一下. 7、接不定式 11)I decided to write rather than telephone.我决定写信而不是打电话. 12)They prefer to die fighting rather than live in enslavement. 他们宁可战死,也不肯活着受奴役. 13)I prefer to work rather than remain idle.我宁愿工作而不愿闲着. 8、接谓语动词 14)He told a lie rather than get his friend into trouble. 他宁愿说谎也不愿连累朋友. 15)Shall we go for a walk rather than watch television? 咱们不看电视,出去散步,好不好? 16)He ran rather than walked.他跑步而不是步行. rather than后接动词原形表示主观抉择,接一个动词的过去式则表示客观差异. 9、接从句 17)It was what he meant rather than what he said. 那是指他话中的意思,而不是他所说的话. 18)It was what he had caten rather than what he had drunk that made him ill.使他得病的不是他喝的东西,而是他吃的东西. 二、rather than用作介词 R.Quirk编著的《英语语法大全》p.1387明确指出:和as well as及in stead of一样,rather than后面跟一个和母句中的动词形式并不匹配的ing分词分句时,它是介词,而不是准并列连词: 19)Their actions precipitated the war rather than averting it. 他们的行为促使战争爆发而不是避免战争. 20)Rather than a new car,he bought a colour television. 他买了一台彩电,而不是一辆新车. 21)Let"s finish the job today,rather than leaving it till tomorrow. 让咱们今天干完工作,而不是留到明天. 三、rather than用作从属连词,引导一种优选分句.

rather和quite的区别

这三个词,按程度强弱排列,顺序为:rather, quite, very(fairly)。 very(fairly)多用于褒义,如very(fairly) good; rather多用于贬义形容词、too及比较级前。 quite,rather与单数名词连用,冠词放在其后。但当rather,quite 前仍有形容词,不定冠词放其前后均可,如:rather a cold day/a rather cold day。 quite和rather可修饰名词,置于“不定冠词+名词之前”。如:quite a good story, rather a strong wind。 副词quite修饰可比较的形容词时,意为”相当”。如:That”s quite good. 当它修饰不可比较的形容词时,则意为”十分或完全”。如:She is quite right.” quite有两个实际上相反的意思: (1)”有点;相当地”,往往与”可分级”的形容词(能被more, less和very修饰的形容词)搭配。如:a quite pleased afternoon 一个相当令人愉快的下午; (2)”全部地;完全地”,倾向修饰绝对形容词(即不能被more, less和very修饰的形容词)。如:a quite outstanding performance一场非常出众的表演。(当quite涉及动词和副词时,同样的区别也适用) 修饰perfect完美的,如果用fairly程度太弱,与这个词的意思不符;如果用rather,有一些消极的意思。而very是修饰具有比较级的形容词,而perfect 是没有是不可比较的。所以本题选D。 fairly, quite, rather 这三个副词都可用来说明形容词和副词的程度,十分容易混淆。 1.fairly意为“相当,还算”,是这一组词中语气最轻的一个。quite为“相当,或多或少地,在某种程度 上”,语气比fairly稍强。rather为“相当,有点,颇”,在这三个副词中语气最强。试比较下列各句: This film is fairly good. This film is fairly good. 这部电影还可以看看。 Your composition is quite good. Your composition is quite good. 你的作文还不错。 His homework is rather good. rk is rather good. 他的作业相当不错。 又如: This book is fairly easy. This book is fairly easy. 这本书还算浅易。 He is quite grown up. He is quite grown up. 他差不多长大成人了。 That is rather hard to explain right away. That is rather hard to explain right away. 要立即说明是颇有难度的 2.fairly只用于修饰褒义的形容词和副词,如可以说She is fairly clever,不可说She is fairly She is fairly foolish。rather主要用于贬义,如rather poor/bad/stupid/ugly,但它也可以用在某些褒义的形容词 和副词前,具有比fairly更强烈的褒义,相当于very,如rather good/ well/pretty /clever。另外, 若在没有褒贬意义的词前用fairly,表示说话人赞同;若用rather,则表示不赞同。试比较: This soup is fairly hot. This soup is fairly hot. 这汤蛮热的。 This soup is rather hot. er hot. 这汤太烫了。 She is fairly tall for her age. She is fairly tall for her age. 就她的年龄来说,她长得算是高了。 She is rather tall for her age. She is rather tall for her age. 就她的年龄来说,她长得过于高了。 3.rather可与too及比较级连用,而fairly和quite则不可。如: My mother is rather better today. My mother is rather better today. 我母亲今天病好多了。 This book is rather too difficult for the juniors and rather too easy for the seniors. ifficult for the juniors and rather too easy for the seniors. 这本书对低年级学生说来未免太难,对高年级学生说来又嫌太容易。 4.quite和rather还可和动词连用,fairly则不可和动词连用。如: This does not quite satisfy me. This does not quite satisfy me. 这没有完全使我满意。 I don”t quite follow you. t quite follow you. 我不大懂你的话。 They rather expected to win the match. d to win the match. 他们颇想赢得这场比赛。 I rather like her. I rather like her. 我相当喜欢她。 5. quite和rather都可修饰名词,但须放在不定冠词前。如: That was quite an accident. That was quite an accident. 那是一次不太寻常的事故。 It”s rather a pity. s rather a pity. 这真是相当遗憾。 当名词前有形容时,quite和rather可放在不定冠词后,也可放在不定冠词前。如: They had a quite good time. 也可说quite a good time。 It is a rather cold day. 也可说rather a cold day。 Such as 后面要直接接名词,代词或动名词等。另外,还是,凡是的意思。Wild animals such tigers and lions are becoming rare. Such as remains will be yours when I died. 所有财产都是你的。 For example 后面要加逗号再接名词等,还可以位于句末,而将名词放在其前面。 I have many friends, Alice for example (for example , Alice).

Rather."“那么,他的确和它有些家族渊源,是不是?”——“噢,是的,的确如此。”Usage Note : Rather, pretty, quite, and fairly can all be used to modify adjectives and adverbs, but are all less strong than very. Rather and pretty are the strongest of these words and are the closest to very. Pretty, in this sense, is informal. Therefore, if you said to someone, ‘Your work is pretty good" or ‘Your work is rather good", they would be more likely to be pleased than if you said ‘Your work is quite good" or ‘Your work is fairly good". However, rather is commonly used with words indicating negative qualities. I was feeling rather sad. It is the only one of these words than can be used with comparatives, and with too. Global warming could be rather worse than we think it will be... He was becoming rather too friendly with my ex-boyfriend. Quite is slightly stronger than fairly, and may suggest that something has more of a quality than expected. Nobody here"s ever heard of it but it is actually quite common.rather, pretty, quite 和 fairly 都可以用于修饰形容词和副词,但是它们都没有very的程度强。rather 和 pretty 在这4个词中程度最强,意思和very最接近。表达这个意思时pretty是非正式说法。因此,如果对某人说Your work is pretty good(你干得非常好)或Your work is rather good(你干得相当好)要比说Your work is quite good(你干得很不错)或Your work is fairly good(你干得还不错)更令他高兴。但是,rather 往往和有消极意义的词连用,如:I was feeling rather sad(我觉得很难过)。在这些词中唯有rather可以和比较级或too连用。如:Global warming could be rather worse than we think it will be(全球变暖可能比我们想象的更加严重),He was becoming rather too friendly with my ex-boyfriend(他和我的前男友好得有些过了头)。quite比fairly的程度稍强一些,表示某物有些超乎人们的期望。如:Nobody here"s ever heard of it but it is actually quite common(这里没有人听说过它,但是它实际上颇为常见)。

rather than 与rather...than的区别 请分析详细些

rather than 用法小结 rather than 是一个并列连词,用法比较复杂,现归纳如下: 1. rather than 与would 连用时,构成“would rather...than...”句式,意思是“宁愿……而不愿……”,表示主观愿望,即在两者之中选择其一.例如: She"d rather die than lose the children. 她宁愿死也不愿失去孩子们. 2. rather than 不与would连用时,表示客观事实,意为“是……而不是……;与其……不如……”.它连接的并列成分可以是名词、代词、形容词、介词(短语)、动名词、分句、不定式、动词等.现分述如下: (1) 连接两个名词或代词 He is an explorer rather than a sailor. 与其说他是一个海员,不如说他是一个探险者. You rather than I are going to go camping. 是你而不是我要去要野营. 注意:rather than 连接两个名词或代词作主语时,谓语动词应与rather than 前面的名词或代词在人称和数上保持一致. (2) 连接两个形容词 The sweater she bought was beautiful rather than cheap. 与其说她买的这件羊毛衫便宜不如说它漂亮. (3) 连接两个介词(短语)或动名词 We will have the meeting in the classroom rather than in the great hall. 我们是在教室里开会,不是在大厅里. She enjoys singing rather than dancing. 她喜欢唱歌,而不喜欢跳舞. (4) 连接两个分句 We should help him rather than he should help us. 是我们应该帮助他而不是他应该帮助我们. (5) 连接两个不定式 I decided to write rather than (to) telephone. 我决定写信而不打电话. 注意:rather than 后接不定式时,不定式可以带to,也可以不带to, 如上句.但rather than位于句首时,则只能接不带to 的不定式.如:Rather than allow the vegetables to go bad, he sold them at half price. 他唯恐蔬菜烂掉,把它们以半价卖掉了. (6) 连接两个动词 He ran rather than walked. 他是跑来的,而不是走来的. 注意:这里rather than 后用了walked,而没有用walk,表示客观事实,而不是主观愿望.如果换成walk,则作“宁愿……而不愿 ……”解. would rather的用法 一、would rather意思是“宁愿、宁可、更、最好、还是为好”,后接动词原形,常省略为"d rather,表示优先选择的一种方式 其否定形式是would rather not do sth.would rather没有人称和数的变化,所有的人称一律用would rather. “would rather+动词原形”是英语中常见的一个惯用句式,美国英语中多用had rather.would (had)在此决无“过去”之意,它是一个情态助动词,且无词性、时态变化. 例 Mr Li would rather not listen to rock music. 李先生不愿意听摇滚音乐. If you"d rather be alone, we"ll all leave here. 如果你宁愿独自呆着,那我们都离开这儿. He"d rather work in the countryside. 她宁可到农村去工作. You would rather stay at home and do some reading this evening. 今晚你最好呆在家中读点书. 二、如果在两者中进行取舍,表示“宁愿……而不愿……,与其……宁可……”的意思时,则可用would rather…than…或would…rather than…的句型 例 I would rather watch TV at home than go to the cinema. 我宁可在家看电视而不愿去看电影. The children would walk there rather than take a bus. 孩子们宁愿步行去那里而不愿乘公共汽车. 请注意 1) would rather…than…/would…rather than…也可以颠倒为:rather than…would….Would(rather)和than后都接不带to的动词不定式,若选用的动词相同,那么than 后的动词可以省略. 例 I would rather have noodles than rice. 我宁愿吃面条也不吃米饭. He would rather drink wine than beer. 他喜欢喝红葡萄酒而不喜欢喝啤酒. Rather than work in such bad condition, he would give up. 与其在这样差的条件下工作,他宁愿放弃. 2)使用would rather…than…句型时要注意“平行结构”,即在than 的前后要用两个同类的词或词组,如两个名词、两个不定式、两个介词短语等. 例 I would rather go to work by bike than by bus. 我宁愿骑自行车也不愿乘公共汽车去上班. I would rather talk with his mother than with his father. 我宁愿和他妈说话而不愿和他爸说话. 三、在疑问句式中,would rather 与would rather…than…中的would要放在主语之前 例 Would you rather stay here or go home? 你愿意呆在这里,还是回家? Which would you rather have, apples or bananas? 你喜欢吃苹果还是香蕉? Would you rather read a novel than read a poem?你宁愿看小说而不愿朗读诗歌吗? 四、would rather+从句,是一个常用的虚拟语气句型 Would rather+从句,谓语一般用过去时来表示现在或将来.其意为“宁愿……,还是…… 好些”“一个人宁愿另一个人做某事”.引导从句的that常省略.在谈到过去的动作时,谓语则用过去完成时. 例 John wants to see me today. I would rather he came to tomorrow than today. 约翰今天想去看我.我宁愿他明天来看我而不是今天.(句中came不是表示过去而是表示将来) We"d rather he paid us the money tomorrow. 我们宁愿他明天付给我们那笔钱. Don"t come tomorrow. I"d rather you came next weekend. 明天别来.我希望你下周末来. 请注意 1) 如果谈到过去的动作,也就是表示过去已经发生的事情在选择上不恰当.此时,主句一般为I had rather ,其(that)从句则用过去完成时. 例 Would rather you had not done that. 我真希望你没有做那件事. 2)如果只涉及主语本人而不涉及另一个人,则would rather之后不接that从句而接have done结构. 例 I would rather have gone to the theatre than stayed home night. 我真希望昨天晚上去看了戏而不是呆在家里. He would rather be poor than have got money by dishonest methods. 他宁可穷也不愿意用不诚实的手段获取金钱. Henry would rather that his girlfriend worked in the same department as he does.亨利希望他的女朋友和他在一个部门工作. 五、would rather/sooner和prefer/would prefer的区别 would rather和would sooner之间一般没有区别,但经常接触到的是would rather. 例Tom would rather/sooner read than talk. 汤姆宁可读书而不愿谈天. Tom prefers reading to talking.汤姆喜欢读书而不喜欢谈天. 请注意 1)would rather后跟不带to的不定式+than+不带 to的不定式,而prefer后跟动名词+to+动名词.有时prefer后面也可跟名词,而在would rather之后要求只带动词原形. 例 He prefers wine to beer.= He would rather drink wine than beer. 他喜欢喝红葡萄酒而不喜欢喝啤酒. I prefer tennis to golf.= I"d rather play tennis than golf. 我喜欢打网球而不喜欢打高尔夫球. 2)某些 prefer+名词的情况不能用 would rather完全确切地表达出来:He prefers dogs to cats.(他喜欢狗而不喜欢猫.)和 He would rather have dogs than cats.(他宁可养狗而不愿养猫.)很明显,这两句的意思并不完全相同. 3) would rather+不带to的不定式有时可代替 would prefer+带 to的不定式. 例 I"d rather fly than go by sea.=I"d prefer to fly. 我宁愿乘飞机也不愿乘船. 这两个结构后面带名词时情况也一样: 例 —Would you like some gin? —I"d prefer a coffee.=I"d rather have coffee than gin. —您想喝点杜松子酒吗? —我想喝点咖啡./我想喝点咖啡,不想喝杜松子酒. 4)would rather/sooner和would prefer后面都可跟完成式,但后者带to. 例 We went by sea but I"d rather have gone by air=I"d prefer to have gone by air. 我们是乘船去的,可我本想乘飞机去.(我愿意乘飞机去,可我的愿望未能实现.)这和 would like+不定式的完成式有点相似,would like+带to 的不定式的完成式也表示未能实现的愿望. 我搜到的,不知道有没有用

飞机票上的ET是什么意思?

ET的全写是Electronic Ticket,意思就是指电子机票,又叫电子客票。电子机票也称电子客票客服,是纸质机票的电子形式,是一种电子号码记录电子机票将票面信息存储在订座系统中,可以像纸票一样执行出票、作废、退票、换开、改签等操作。电子机票依托现代信息技术,实现无纸化、电子化的订票、结账和办理乘机手续等全过程。对于旅客来讲,它的使用与传统纸质机票并无差别。实行电子客票,就是将纸质车票承载的旅客运输合同凭证、乘车凭证、报销凭证功能相分离,依据有关法律条文规定,以电子数据作为铁路旅客承运合同凭证,推进乘车凭证无纸化和多样化。扩展资料:实行电子客票后,旅客购票、检票、乘车等流程将更加方便快捷。以海南环岛高铁为例,旅客通过互联网购票成功后,可以在网站上自行打印或下载购票信息单,也可以在海南省内各车站售票窗口、自动售/取票机、代售点打印;通过售票窗口和自动售/取票机购票的,购票成功后旅客将收到购票信息单,并可根据需要选择是否打印报销凭证。进站和检票时,持二代身份证、外国人永久居留证、港澳台居民居住证、港澳居民来往内地通行证、台湾居民来往大陆通行证五种可机器识读证件的旅客,可直接使用证件自助核验及检票乘车;持不可机器识读购票证件的旅客,在专用实名验证口和检票口,由工作人员扫描其购票信息单二维码或手工输入其证件号码核验进站乘车。参考资料来源:人民网——一证走天下 电子客票来了

创建代码生成器可以很简单:如何通过T4模板生成代码?[下篇]

但是这是一种基于单个文件的解决方案,即我们必须为每一个生成的存储过程建立一个模板。如果我们提供一种基于多文件的代码生成方式,将会为编程人员带来极大的便利。借助于T4 ToolBox这个开源工具箱,多文件的SQL Generator的实现变得异常简单。[文中的例子可以从这里下载]目录 二、创建自定义的Generator 三、ProcedureGenerator如何被使用?一、多文件代码生成器会带来多大的便利?我们先来直观的感受一下较之《上篇》提供的单一文件的代码生成器,基于多文件的代码生成解决方案会为开发人员带来多大的便利。 同样对于《上篇》创建的数据表T_PRODUCT,之前我们为了生成三个不同的存储过程,我们不得已需要创建3个不同的T4模板文件。实际上我们更需要的方式只需要创建一个T4模板,让我们的SQL Generator自动为我们生成3个包含相应存储过程的.sql附属文件,如左图所示(点击看大图)。有的时候,基于单个数据表的存储过程生成方式我们依然觉得不方便。如果我们能够在T4模板文件中指定的数据表的列表,让我们的SQL Generator为列表的每一个数据表都生成CUD三个存储过程,这样的方式更加具有吸引力。如右图所示(点击看大图),一个订单模块包含两个具有主子关系的两张表(T_ORDER和T_ORDER_DETAIL),现在我们在一个T4模板中指定这两个表明,通过SQL Generator可以帮助我们生成6个包含存储过程的.sql附属文件。甚至有的时候我们连数据表列表都无需指定,让SQL Generator为所有的表都生成相应的存储过程。我的例子中没有提供这样的功能,但是实现自来不会存在任何问题。二、创建自定义的Generator在《上篇》中我创建了一个抽象的ProcedureTemplate类,以及三个基于生成CUD存储过程的具体ProcedureTemplate:InsertProcedureTemplate、UpdateProcedureTemplate和DeleteProcedureTemplate。它们都将直接服务于我们今天将要提供的基于多文件的SQL Generator。在《上篇》中,这四个Template分别定义在4个不同的TT文件中,3个具体的ProcedureTemplate通过<#@include>指令将抽象ProcedureTemplate模板文件包含过来。由于我们将要创建的T4模板将会使用到这四个类,如果我们用四个<#@include>指令将四个TT文件包含过来,由于T4引擎将会导致对ProcedureTemplate的4次包含,最好将会导致变异问题。个人觉得这应该算是T4引擎解析包含关系的一个局限性,为了解决这个问题我们不得不抽象的ProcedureTemplate和三个具体的ProcedureTemplate都合并成一个TT文件。T4 ToolBox为类库中为了提供了一个抽象的T4Toolbox.Generator类用于实现多文件的代码生成。为此我们创建一个TT模板文件,定义了如下一个继承自该类的ProcedureGenerator。ProcedureGenerator的核心是通过属性Templates定义的类型为IEnumerable<ProcedureTemplate>的ProcedureTemplate列表,这个列表在存储过程中进行初始化。而对于ProcedureGenerator的构造函数,处理定义了一个表示数据库连接字符串的databaseName的参数外,并以数组参数的形式指定了生成的存储过程基于的数据表名的列表。<#@ import namespace="System.Collections.Generic" #><#@ include file="ProcedureTemplate.tt" #><#@ include file="T4Toolbox.tt" #><#+publicclass ProcedureGenerator : Generator{public IEnumerable<ProcedureTemplate> Templates{get; private set;}public ProcedureGenerator(string databaseName, paramsstring[] tableNames) {if(null == tableNames || tableNames.Length == 0) {thrownew ArgumentNullException("tableNames"); } this.Templates = InitlizeTemplates(databaseName,tableNames); }private IEnumerable<ProcedureTemplate> InitlizeTemplates(string databaseName, string[] tableNames) { foreach(string tableName in tableNames) {yieldreturnnew InsertProcedureTemplate(databaseName, tableName);yieldreturnnew UpdateProcedureTemplate(databaseName, tableName);yieldreturnnew DeleteProcedureTemplate(databaseName, tableName); } }protectedoverridevoid RunCore() {foreach(ProcedureTemplate tempalte inthis.Templates) { tempalte.RenderToFile(tempalte.GetProcedureName() + ".sql"); } }}#>真正的存储过程的T-SQL脚本实现在重写的RunCore中。由于具体的文本转化逻辑都定义在了ProcedureTemplate中了,所以在这里我们需要遍历的ProcedureTemplate集合中每一个Template对象,调用RenderToFile方法将相应的存储过程的脚本写入以存储过程命名同名的.sql文件中。三、ProcedureGenerator如何被使用?我们最后来看看我们创建的ProcedureGenerator最终如何被应用于具体的代码生成。其实很简单,我们只需要创建相应的模板文件,通过<#@include>将定义ProcedureGenerator类的TT文件包含近来,最后以代码语句调用块(<#StatementCode#>)的形式实力化该对象,并调用Run方法即可。在构造函数中指定数据库连接字符串的名称和数据表名的列表。下面是基于但表的T4模板。<#@ template language="C#" hostSpecific="true" debug="true" #><#@ include file="TemplatesProcedureGenerator.tt" #><#new ProcedureGenerator("TestDb","T_PRODUCT").Run();#>下面是基于多表的T4模板:<#@ template language="C#" hostSpecific="true" debug="true" #><#@ include file="TemplatesProcedureGenerator.tt" #><#new ProcedureGenerator("TestDb","T_ORDER","T_ORDER_DETAIL").Run();#>当你代码生成工作执行之后,会多出一个与TT文件同名的附属文件,你需要手工删除掉它。从数据到代码——通过代码生成机制实现强类型编程[上篇]从数据到代码——通过代码生成机制实现强类型编程[下篇]从数据到代码——基于T4的代码生成方式

A3的纸尺寸是多少?

A3,是指纸张的规格。按国际通用标准A3规格的纸张,其大小为297mm×420mm,是A4纸的2倍;按国家纸张开本行业标准 (GB/T 1999 ) 又叫做 "大 8 开 "。A3纸的规格标准依据来源于ISO 216。ISO 216是国际标准化组织(ISO)所定义的纸张尺寸国际标准,为今日世界上大多数国家所使用。知名的A4纸张大小即为此标准所发展出来。 这个标准最初是德国标准化学会(DIN)在1922年纳入的DIN476,虽然其中一些格式法国在同一时期也自行研发出来,不过之后就被遗忘了。扩展资料:A3纸指的是国际通用标准A3规格的纸张,其大小为297mmχ420mm,是A4纸的2倍。--- A3 规格的纸张按国家纸张开本行业标准 (GB/T 1999 ) 又叫做 "大 8 开 "国家标准中图纸从小到大一般可分为A5、A4、A3、A2、A1、A0,其中A0到A3图幅在图纸比较常用。各种图号图纸的长边与短边的比例一致,均为1.414213562,也就是2的开根号,换句话说图纸差一号,面积就差一倍。按照纸张幅面的基本面积,把幅面规格分为A系列、B系列和C系列,幅面规格为A0的幅面尺寸为841毫米×1189毫米,幅面面积为1平方米;B0的幅面尺寸为1000毫米×1414毫米,幅面面积为1.41平方米;C0的幅面尺寸为917毫米×1279毫米,幅面面积为1.17平方米;复印纸的幅面规格只采用A系列和B系列。若将A0纸张沿长度方式对开成两等分,便成为A1规格,将A1纸张沿长度方向对开,便成为A2规格,如此对开至A8规格。其中A3、A4、A5、A6和B4、B5、B6 7种幅面规格为复印纸常用的规格。参考资料:A3 (A3 纸张规格)百度百科

iOS原生框架Vision实现瘦脸大眼特效

一般短视频项目中会使用类似 Face++ 这样的商业sdk实现瘦脸大眼特效,想到苹果的原生框架 Vision 也可以进行人脸识别,提取人脸特征点,应该也能实现。没想到挺顺利,参考了网上的相关算法,个把小时就实现了效果。 Vision 与 Face++ 对比: 1. Vision 原生框架,体积小,免费; Face++ 需要付费,包大概50M左右。 2. Vision 要求在ios11以上, Face++ 貌似没有。 3. Vision 检测人脸关键点数量在iphone 5S,iphone7上为74个,iphone XS上为87个。 Face++ 检测人脸关键点数量为106个。 4. Vision 特征点貌似有点飘(稳定性一般),边缘检测不是很准。 Face++ 特征点相对贴合的要准一点。 Vision官方文档 Face++官方文档 1.使用 GPUImageVideoCamera 采集摄像头数据。 2.将采集到的数据 CVPixelBufferRef 送入 Vision 处理,拿到人脸特征点。 3.自定义的瘦脸大眼滤镜,添加到 GPUImage 的滤镜链上。 4.在自定义滤镜中重写 - (void)renderToTextureWithVertices:(const GLfloat *)vertices textureCoordinates:(const GLfloat *)textureCoordinates 方法,将特征点送入片元着色器中处理。 5.着色器中使用瘦脸大眼相关算法:圆内放大算法,圆内缩小算法,定点拉伸算法。 算法原理解析 6.最后通过 GPUImageView 展示。 1.将采集到的图像原始数据 CVPixelBufferRef 送入 Vision 处理 2. Vision 提取人脸特征点,需要注意的是特征点的坐标转换。 3.在 FaceBeautyThinFaceFilter 滤镜中处理特征点。 4.在片元着色器处理特征点数据。 第一张为原图,第二张为瘦脸大眼效果。可以看到,大眼效果不太自然,原因是系数设置的较大。 1.如图所示,取出左眼瞳孔特征点72的坐标和上方特征点13的坐标。 2.以瞳孔72为圆心,以72和13的距离的5倍为半径,确定放大范围。 3.按照圆内放大算法,离圆心越近的像素向圆圈外部偏移量越大,离圆心越远的像素偏移量越小。所以眼睛的纵向被拉伸的程度比较明显。而且又能让放大区域和未放大区域实现平滑过渡。 4.其他圆内缩小,定点拉伸的算法其实也是类似,就不再赘述。 Github:Demo地址 欢迎留言或私信探讨问题及Star,谢谢~
