因为t1表中两个字段都关联了mast表

产生的效果相当于

SELECT t1.a1,c.aname,t1.b1,c.bname

from yewu t1

left join mast c on (t1.a1=c.a and t1.a2=c.b)

where t1.a1=c.a and t1.b1=c.b

union all

SELECT t1.a2,d.aname,t1.b2,d.bname

from yewu t1

left join mast d on (t1.a2=d.a and t1.a2=d.b)

where t1.a1=c.a and t1.b1=c.b

She felt left out怎么分析这句的语法

Shefeltleftout.是一个“主系表”句型,She是主语,felt是系词,leftout是过去分词作表语。过去分词含有被动意义,所以句意是“她感到被冷落了”。

left join 和 left out join 有什么区别?

用 LEFT JOIN 运算 创建左边外部联接.左边外部联接将包含了从第一个(左边)开始的两个表中的全部记录,即使在第二个(右边)表中并没有相符值的记录。在Left Outer JOIN中,所有左边表中的行都出现在结果数据集中。是OUTER,不是out。SQL语句里面的,去计算机方面问最好了

Thereare14ofusleftoutof33,到底多少人留下了?

唐代的诗人特别多。李白、杜甫、白居易固然是世界闻名的伟大诗人,除他们之外,还有其他无数诗人,象满天的星斗一样。这些诗人,今天知名的就还有二千三百多人。他们的作品,保存在《全唐诗》中的也还有四万八千九百多首。唐诗的题材非常广泛。有是从侧面反映当时社会的阶级状况和阶级矛盾,揭露了封建社会的黑暗;有的歌颂正义战争,抒发爱国思想;有的描绘祖国河山的秀丽多娇;此外,还有抒写个人抱负和遭遇的,有表达儿女爱慕之情的,有诉说朋友交情、人生悲欢的等等。总之从自然现象、政治动态、劳动生活、社会风习,直到个人感受,都逃不过诗人敏锐的目光,成为他们写作是题材。在创作方法上,既有现实主义的流派,也有浪漫主义的流派,而许多伟大的作品,则又是这两种创作方法相结合的典范,形成了我国古典诗歌的优秀传统。 《全唐诗》序中,谓全书共“得诗四万八千九百余首,凡二千二百余人”,后人多从其说。其实,玄烨所举数并不精确,近年日本学者平冈武夫编《唐代的诗人》、《唐代的诗篇》,将《全唐诗》所收作家、作品逐一编号作了统计,结论是:该书共收诗四万九千四百零三首,句一千五百五十五条,作者共二千八百七十三人。这个数字是相当可靠的。

feel left out为什么用left

left为过去分词,这句话是被动语态,但因为be动词与feel都为系动词,一个句子中不能出现两个动词,所以只出现feel没有出现be动词。句子意为这样她就不会觉得被冷落了。 重点词汇解释: 1、feel vt.感觉;认为;触摸;试探 vi.觉得;摸索 n.感觉;触摸 2、left adj.左边的;左派的;剩下的 adv.在左面 n.左边;左派;激进分子 v.离开

left out join和right join的区别是什么?

left out join 左连接,简单来说,若果是左连接,则保留左表所有的行;即使在右表 (Orders) 中没有匹配的行。同理,如果是right join,则保留右表所有的行,即使在左表 (table_name1) 中没有匹配的行。多表外链接查询语句use+数据库select+查询列名from+表1left/right (out) join +表2on 表2的列=表1的列扩展资料:结构化查询语言(Structured Query Language)简称SQL(发音:/u02c8es kjuu02d0 u02c8el/ "S-Q-L"),是一种特殊目的的编程语言,是一种数据库查询和程序设计语言,用于存取数据以及查询、更新和管理关系数据库系统;同时也是数据库脚本文件的扩展名。结构化查询语言是高级的非过程化编程语言,允许用户在高层数据结构上工作。它不要求用户指定对数据的存放方法,也不需要用户了解具体的数据存放方式,所以具有完全不同底层结构的不同数据库系统, 可以使用相同的结构化查询语言作为数据输入与管理的接口。结构化查询语言语句可以嵌套,这使它具有极大的灵活性和强大的功能。1986年10月,美国国家标准协会对SQL进行规范后,以此作为关系式数据库管理系统的标准语言(ANSI X3. 135-1986),1987年得到国际标准组织的支持下成为国际标准。不过各种通行的数据库系统在其实践过程中都对SQL规范作了某些编改和扩充。所以,实际上不同数据库系统之间的SQL不能完全相互通用。

android verticalviewpager 怎么控制滑动翻页距离

  下面的代码片段详细说明了如何实现滑动翻页。  复制代码 代码如下:  public class ViewFlipperActivity extends Activity implements OnGestureListener {  private static final int FLING_MIN_DISTANCE = 100;  private ViewFlipper flipper;  private GestureDetector detector;  @Override  protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.viewflipper);  // 注册一个GestureDetector  detector = new GestureDetector(this);  flipper = (ViewFlipper) findViewById(R.id.ViewFlipper);  ImageView image1 = new ImageView(this);  image1.setBackgroundResource(R.drawable.image1);  // 增加第一个view  flipper.addView(image1);  ImageView image2 = new ImageView(this);  image2.setBackgroundResource(R.drawable.image2);  // 增加第二个view  flipper.addView(image2);  }  @Override  public boolean onTouchEvent(MotionEvent event) {  // 将触屏事件交给手势识别类处理  return this.detector.onTouchEvent(event);  }  @Override  public boolean onDown(MotionEvent e) {  return false;  }  @Override  public void onShowPress(MotionEvent e) {  }  @Override  public boolean onSingleTapUp(MotionEvent e) {  return false;  }  @Override  public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,  float distanceY) {  return false;  }  @Override  public void onLongPress(MotionEvent e) {  }  @Override  public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,  float velocityY) {  if (e1.getX() - e2.getX() > FLING_MIN_DISTANCE) {  //设置View进入和退出的动画效果  this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,  R.anim.left_in));  this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,  R.anim.left_out));  this.flipper.showNext();  return true;  }  if (e1.getX() - e2.getX() < -FLING_MIN_DISTANCE) {  this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,  R.anim.right_in));  this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,  R.anim.right_out));  this.flipper.showPrevious();  return true;  }  return false;  }  }  在这段代码里,创建了两个IamgeView(用来显示图片),加入到了ViewFlipper中。程序运行后,当用手指在屏幕上向左滑动,会显示前一个图片,用手指在屏幕上向右滑动,会显示下一个图片。实现滑动切换的主要代码都在onFling()方法中,用户按下触摸屏,快速移动后松开,就会触发这个事件。在这段代码示例中,对手指滑动的距离进行了计算,如果滑动距离大于100像素,就做切换动作,否则不做任何切换动作。

out 在此处的意思有超出,在。。。之外的意思,left意思为剩余的,结合汉语翻译“信、达、雅”的要求,综合起来意思就是突如其来,出乎意料。翻译搞笑一点儿就是:惊不惊喜?

天工开物卷跋文言文

1. 帮我翻译一下《天工开物 序》原文 天工开物序/宋应星(戴文和译) 上天覆盖、大地承载,物的数目,号称上万,产生的事情也因为这样而委曲、变通到完成,没遗漏什麽,这那里是人力造成的呢!既然事物多到上万的数量,如果一定要别人口头传授、自己亲眼看到,然后才能够认识的话,那能认识的事物有多少呢?在万事万物里头,其中无益人类和有益人类的,它们各占了一半。世上有些绝顶聪明、博通事物的人,众人都很推崇他──他乃至於连枣梨的花都不认识,却凭空猜测楚王的萍宝;连釜鬵(饭锅)一般的样式都很少见过,却在夸谈楚国的方鼎。画家们喜欢画鬼魅,却不喜欢画狗和马,就算是(博学多闻)的郑国公孙侨、晋代张华,又那里值得称赞呢! 我很幸运地生在明白事物顶盛的时代,云南的车马,可以顺利通贯到辽阳;岭南边地的官宦、商人,可以任意到蓟北游览。在方圆万里里面,有什麽事、什麽物没办法见见呢?没办法看看呢?如果读书人是生在东晋初年或南宋末叶,那麽他看到燕、秦、晋、豫各地的土产,一定错当成是外国(族)的物品了。从与外国(族)贸易处买到的皮衣、皮帽,和古代肃慎的楛矢有什麽不一样呢?而且那些王孙、皇子,从小生长在深深的宫殿内,御厨里精白的米粒正发出香味的时候,就想到要看看耒耜的农具;宫内女官正在裁剪锦绣衣裳,就会去想像什麽是纺织机和丝线。如果在这个时候,能够翻图看一看的话,那就如获至宝了。这些年来我写了一本书,名叫做「天工开物卷」。真悲伤啊!我实在太穷了,虽想要买些奇(罕)的书籍来加以考证,却苦於没有充裕的财力;虽想要招请志同道合的朋友,研究商量里头的真假,却缺乏能够招待宾友的客馆。只好这样子任它孤陋、任它寡於见闻,而把疑问埋藏在内心里而来撰写它,这难道是恰当的吗? 我的朋友涂伯聚先生,意念真诚,感动天地,心思灵敏、穷究事物的道理,凡是古今有一句好话,有可取的小长处,一定勤勤恳恳和它相投合、相成全。去年我的《画音归正》一书,就是由於先生的赞助而付印出版;现在又有后续的使命,再拿这本书来继续前书的赞助、付印。这也是往日的缘分相召相牵吧! 这本书分前后卷,首卷为,末卷为,这是用来表示看重五谷而看轻金玉的意义。其中、二卷,他们的道理过於精深,我自己衡量并非我的专长所在,所以在付印之际就把它们删掉了。我请求那些追求高深学问的文人们,把这本书丢掷到桌上去吧!因为它对於登科中第、升官出名是一点关系也没有的啊! 时间是崇祯十年四月,奉新宋应星写於自家的问堂里。 呵呵!~从网上抄来的!~ 2. 天工开物全文 《天工开物卷》序 天覆地载,物数号万,而事亦因之,曲成而不遗。岂人力也哉? 事物而既万矣,必待口授目成而后识之,其与几何?万事万物之中,其无益生人与有益者,各载其半。世有聪明博物者,稠人推焉;乃枣梨之花未赏,而臆度楚萍;釜鬵之范鲜经,而侈谈莒鼎;画工好图鬼魅而恶犬马;即郑侨、晋华,岂足为烈哉? 幸生圣明极盛之世,滇南马纵贯辽阳,岭徼宦商〔商〕衡游蓟北,为方万里中,何事何物不可见见闻闻?若为士而生东晋之初、南宋之季,其视燕、秦、晋、豫方物,已成夷产,从互市而得裘帽,何肃慎之失也。且夫王孙帝子,生长深宫,御厨玉粒正香,而欲观耒耜;尚宫锦衣方剪,而想象机丝。当斯时也,披图一观,如获重宝矣! 年来著书一种,名曰《天工开物卷》。伤哉贫也!欲购奇考证,而乏洛下之资;欲招致同人,商略赝真,而缺陈思之馆。随其孤陋见闻,藏著方寸而写之,岂有当哉?吾友涂伯聚先生,诚意动天,心灵格物,凡古今一言之嘉,寸长可取,必勤勤恳恳而契合焉。昨岁《画音归正》由先生而授梓。兹有后命,复取此卷而继起为之,其亦夙缘之所召哉!卷分前后,乃“贵五谷而贱金玉”之义。《观象》、《乐律》二卷,其道太精,自揣非吾事,故临梓删去。 丐大业文人弃掷案头!此书于功名进取毫不相关也。时 崇祯丁丑孟夏月,奉新宋应星书于家食之问堂 《天工开物u2022乃粒第一》 《天工开物u2022乃服第二》 《天工开物u2022彰施第三》 《天工开物u2022粹精第四》 《天工开物u2022作咸第五》 《天工开物u2022甘嗜第六》 《天工开物u2022陶埏第七》 《天工开物u2022冶铸第八》 《天工开物u2022舟车第九》 《天工开物u2022锤锻第十》 《天工开物u2022燔石第十一》 《天工开物u2022膏液第十二》 《天工开物u2022杀青第十三》 《天工开物u2022五金第十四》 《天工开物u2022佳兵第十五》 《天工开物u2022丹青第十六》 《天工开物u2022曲蘖第十七》 《天工开物u2022珠玉第十八》 3. 天工开物全文 《天工开物》记载了明朝中叶以前中国古代的各项技术。 全书分为上中下三篇18卷。并附有121幅插图,描绘了130多项生产技术和工具的名称、形状、工序。 《天工开物》序: 天覆地载,物数号万,而事亦因之。曲成而不遗。 岂人力也哉。事物而既万矣,必待口授目成而后识之,其与几何?万事万物之中,其无异生人与有益者,各载其半。 匹有聪明博物者,稠人推焉.乃枣梨之花未赏,而臆度“楚萍”;釜鬻之范鲜经,而侈谈“莒鼎”;画工好图鬼魅而恶犬马,即郑侨、晋华岂足为烈哉? 幸生圣明极盛之世,滇南车马纵贯辽阳,岭徼宦商横游蓟北。为方万里中,何事何物不可见见闻闻!若为士而生东晋之初、南宋之季,共视燕、秦、晋、豫方物已成夷产,从互市而得裘帽,何殊肃慎之矢也。 且夫王孙帝子生长深宫,御厨玉粒正香而欲观未耜,尚宫锦衣方剪而想象机丝。当斯时也,披图一观,如获重宝矣。 年来著书一种,名曰《天工开物》卷。伤哉贫也,欲购奇考证,而乏洛下之资;欲招致同人商略赝真,而缺陈思之馆。 随其孤陋见闻,藏诸方寸而写之,岂有当哉?吾友涂佰聚先生,诚意动天,心灵格物.凡古今一言之嘉,寸长可取,必勤勤恳恳而契合焉,昨岁《画音归正》,由先生而授梓.兹有后命,复取此卷而继起为之,其亦夙缘之所召哉。 卷分前后,乃“贵五谷而贱金玉”之义。 《观象》、《乐律》二卷,其道太精,自揣非吾事,故临梓删去。丐大业文人弃掷案头,此书与功名进取毫不相关也。 时 祟祯丁丑孟夏月,奉新宋应星书于家食之问堂上篇: 乃粒:关于粮食作物的栽培技术 乃服:衣服原料的来源和加工方法 彰施:植物染料的染色方法 粹精:谷物的加工过程 作咸:介绍盐的生产方法 甘嗜:种植甘蔗及制糖、养蜂的方法 中篇: 陶埏:砖、瓦、陶瓷的制作 冶铸:金属物件的铸造 舟车:船舶、车辆的结构、制作和用途 锤锻:用锤锻方法制作铁器和铜器 燔石:石灰、煤炭等非金属矿的生产技术 膏液:植物油脂的提取方法 杀青:造纸的方法 下篇: 五金:金属的开采和冶炼 佳兵:兵器的制造方法 丹青:墨和颜料的制作 麹蘖:做酒的方法 珠玉:珠宝玉石的来源。 4. 《水经注》,《齐民要术》和《天工开物》的主要内容 《水经注》是我国古代较完整的一部以记载河道水系为主的综合性地理著作; 《齐民要术》是北魏时期的中国农学家贾思勰所著的一部综合性农书; 《天工开物》是第一部关于农业和手工业生产的综合性著作。 以下资料供参考 《水经注》是古代中国地理名著,共四十卷。作者是北魏晚期的郦道元。 《水经注》因注《水经》而得名,《水经》一书约一万余字,《唐六典·注》说其“引天下之水,百三十七”。《水经注》看似为《水经》之注,实则以《水经》为纲,详细记载了一千多条大小河流及有关的历史遗迹、人物掌故、神话传说等,是中国古代最全面、最系统的综合性地理著作。该书还记录了不少碑刻墨迹和渔歌民谣,文笔绚烂,语言清丽,具有较高的文学价值。由于书中所引用的大量文献中很多在后世散失了,所以保存了许多资料。 《齐民要术》大约成书于北魏末年(公元533年-544年),是北朝北魏时期,南朝宋至梁时期,中国杰出农学家贾思勰所著的一部综合性农学著作,也是世界农学史上最早的专著之一,是中国现存最早的一部完整的农书。 全书10卷92篇,系统地总结了六世纪以前黄河中下游地区农牧业生产经验、食品的加工与贮藏、野生植物的利用,以及治荒的方法,详细介绍了季节、气候、和不同土壤与不同农作物的关系,被誉为“中国古代农业百科全书”。 《天工开物》初刊于1637年(明崇祯十年),共三卷十八篇,全书收录了农业、手工业,诸如机械、砖瓦、陶瓷、硫磺、烛、纸、兵器、火药、纺织、染色、制盐、采煤、榨油等生产技术。 《天工开物》是世界上第一部关于农业和手工业生产的综合性著作,是中国古代一部综合性的科学技术著作,有人也称它是一部百科全书式的著作,作者是明朝科学家宋应星。外国学者称它为“中国17世纪的工艺百科全书”。 5. 天工开物一书主要介绍了哪些东西 《天工开物》初刊于1637年(明崇祯十年)。《天工开物》是世界上第一部关于农业和手工业生产的综合性著作,是中国古代一部综合性的科学技术著作,有人也称它是一部百科全书式的著作,作者是明朝科学家宋应星。外国学者称它为“中国17世纪的工艺百科全书”。作者在书中强调人类要和自然相协调、人力要与自然力相配合。是中国科技史料中保留最为丰富的一部,它更多地着眼于手工业,反映了中国明代末年出现资本主义萌芽时期的生产力状况。 《天工开物》共三卷十八篇,全书收录了农业、手工业,诸如机械、砖瓦、陶瓷、硫磺、烛、纸、兵器、火药、纺织、染色、制盐、采煤、榨油等生产技术。尤其是《机械》篇详细记述了包括立轴式风车、糖车、牛转绳轮汲卤等农业机械工具,具有极高的科学价值。 6. 《天工开物· 乃服》译文 乃服:衣服原料的来源和加工方法 天工开物-乃服 (1) 刘和通主读乃服指衣服,词出《千字文》: "乃服衣裳"。 人生四大需要,"衣"它占一席,能不重要?上至帝王贵族,下至贩夫走卒,衣服虽有华丽粗陋之别,但用来御寒及遮掩身体乃是必须的,此也是 *** 最大的区别。本章是全书最长的一章,"衣"之种种,叙述甚详,现在我们说"衣"之重要,其实自古已然。 书上说现今(明朝)像仙女巧妙的织布技术传遍人间,到处都有织布机、提花机 的织造技巧,但又有多少人去了解它?这应该是人生的一大缺憾吧!不但如此,更进一步,应该由衣服原料的由来——属草木之棉、麻、葛;属禽兽昆虫者貂、狐、羊、蚕等加以了解。其中尤属养蚕,还真忙碌得很,由宋朝诗人范成大 诗云:「…乡村四月闲人少,才了蚕桑又插田。 」可知一二;而且养蚕期间,还真叫人念兹在兹,大意不得,宋朝诗人谢枋得即直名,诗曰:「子规啼彻四更时,起视蚕稠怕叶稀….。」这其中的辛苦,外人又能体会多少。 於此,我们来了解蚕的一切,以知丝缕之所自。首先由蛹羽化成蚕蛾,大约十多天,雄雌均同,即破茧而出。 雌蚕蛾身躯较雄蚕蛾为大,但头部一对触角,则雄较雌来得大(今知这是最简单分辨性别的方法)。雌者伏而不动,雄者飞扑,遇雌即交 (据知,乃雌蛾尾端有香水囊,外散气味以诱雄蛾!非盲目之飞也。) 。交配时间为6-8小时,过后雄蛾即死;雌蛾接著产卵,不间断,连续均匀的约生卵二百粒(唯现今文献称少则300粒,多至700粒,是品种改良以致之?或其他?待查。) 产完卵后即不再吃任何东西,不久就会死亡。以事先备妥之厚纸片供蚕卵附著(因卵的外表有一层糊状物质,可附著而不掉落。) 蚕卵可收藏以待来年,但应用竹或木为方架撑之,高悬於梁上透气避日之处,且不得有桐油、烟煤、火气或下雪时应先收藏,待雪过后再悬挂。 为了要淘汰不良之品种,其方法(一):用石灰水或盐水浸泡蚕卵12天,品质不佳者自死即不孵化。(二):露天方式,以竹盘盛之摊於屋顶,任凭霜风雪雨雷电之摧残需12日,亦可达到筛选之效。 蚕有早种(指一年孵化一次,又名一化蚕)、晚种(指一年孵化二次,又名二化蚕)二种,晚种孵出幼虫较早种约早五、六天,结茧亦在先,但茧较早种约轻三分之一。茧有黄、白二色,若将白雄配黄雌,则又可得另一褐色茧。 黄色蚕丝以猪胰脏漂洗可成白色。茧的形状有:二化性蚕如葫芦样、天露浴蚕为椭圆形或扁圆。 清明时节一过天气转暖,蚕即可自行孵化而不必靠衣被遮盖保暖,因此蚕室宜向东南方位,周围缝隙且用纸糊封,上方应有天花板。若再遇寒天,则炭火取暖。 初次喂食蚕蚁时,应将桑叶切细,且桑叶须乾燥,若已达五龄蚕(经过四次脱皮)时,可喂食湿叶,此后吐丝较有光泽。 清除蚕纸的残叶,粪便、脱皮等不洁物,谓之除沙。 懒得除沙,则导致生病或压死;然太过勤快则所得蚕丝太粗。蚕以吃桑叶为大宗,尚有吃柘叶、榆叶、蒿苣叶、生兰叶等。 蚕若是胸部透明发亮,通身黄色,头渐大尾渐小,游走不眠,食量少,即生病了,应即去之,以免传染。蚕经过四次脱皮(蚕宝宝每隔七天要眠一次,不吃不动,经过眠之后,就会开始脱皮。) 称为五龄蚕,体色变黄,且呈透明状,皮肤紧绷,也不爱吃桑叶,即表示将要吐丝结茧。蚕的孵出及开始结茧的时间,均在辰巳 (上午7点至11点)二个时辰。 (此一发现乃世界最早有之纪录)。蚕喜欢温暖,因此初始结茧时,置一小炭火,引其吐丝结茧。 之后,炭再加半斤,使其吐出来之蚕丝随即乾燥,丝质经久而不坏。蚕室通风要良好,靠近炭火之茧不可作为"种"用。 结茧半日可成形,再经一日左右,共约两昼夜就完成。一个蚕茧重约0.3-0.5公克,长约1000-1500公尺。 煮茧抽丝,穷一人之力,日可卷取30两。若丝要粗一点,如绫罗丝,则一次投茧20枚;包头丝细些,只投10来枚。 当蚕茧滚沸时,以竹签拨动水面,即可看到丝绪,用手提绪,绕上鼓轮,且过移丝杆,终至卷丝车上。凡次佳之双茧(双蚕共一茧)或锅底的残茧或蛾口茧则作为丝绵,有人世世代代专门作此丝绵者,此即为棉衣、棉袄之丝也。 打成线, 织成湖绸,价值很高;若用花机织出的产品叫做花绵,则价格更高。为要织造成匹,因此把卷丝车上成卷的丝予以分卷成小丝轴,作为纬丝之用。 一般而言,经丝比纬丝用量少,约4与6之比。而经丝则由小丝轴再牵拉整理,绕於印架上,且定蔻幅;若须上浆者,此时即上浆处理,不上浆者就直接卷於经轴上作为经丝;但不需上浆者,其蔻幅两旁之经丝,各20几条仍需要上浆,用以使布织成后之两边缘较紧固。 上浆之目的,为了增加丝的强度 ,以满足织造时拉伸之力。浆料为作面筋之粉屑,亦有用牛皮胶水上浆者,叫做清胶纱。 上浆后可自乾。有了经轴上的经丝,欲上花机(能织凹凸花样、斜纹之织机之称谓)织造之前, 每条经丝均需穿综度蔻。 且说经丝之数,织罗纱时,织蔻以800齿为准,织绫绢者为1200齿,每个寇齿中所穿的经丝,每四根合成两根,罗纱的经丝共3200根,凌绢丝约5000-6000根,如此多、纤细又不易拿捏的经纱,先穿过。
