CAD中A4图框尺寸为210*297。国家规定的标准标题栏的尺寸为56*180。学校制图作业使用的标题栏尺寸为32*140。对于需要装订的图纸和不需要装订的图纸,每一边留的距离是不一样的。无装订线的e的尺寸为10,有装订线的图纸左侧应该为25。

CAD使我们日常运用的大型软件的一种,跟PS、PR、AI、AE有共通之处,一般的笔记本都可以安装。CAD不仅可以实现二维制图,还可以实现三维制图。它的全称为:Computer Aided Design,中文名为计算机辅助设计,指利用计算机及其图形设备帮助设计人员进行设计工作。

扩展资料:

CAD图框的大小是有国家标准的。常见的图纸有A4、A3、A2、A1、A0。其中A3的大小为两张A4的大小。A2的大小为两张A3的大小,以此类推。国家规定的A3图框的尺寸为297*420,A2为420*594,A1为594*841,A0为841*1189。A0-A4的装订线款均为25。

CAD图框有横向和纵向两种。两者尺寸相同。在日常作图时,可以将标准图框画好后,当做一个可以编辑的块,随用随调取,非常的方便。装配图中一般要有明细栏,明细栏 一般配置在装配图中标题栏的上方。

a4纸张尺寸是多少?

A4规格为21*29.7cm(210mm×297mm),A组纸张尺寸的长宽比都是√2:1,然后舍去到最接近的毫米值。A0定义成面积为一平方米,长宽比为√2:1的纸张。世界上多数国家所使用的纸张尺寸都是采用这一国际标准。这个标准最初是被魏玛共和国在1922年纳入DIN(编号是DIN 476),ISO 216定义了A、B、C三组纸张尺寸。C组纸张尺寸主要使用于信封。扩展资料:A4纸是210mm×297mm的由来:1、一张长为2,宽为X的矩形,对折之后长宽分别是X和1,那么为了保证相似,就要求1:X=X:2。而这个比例正是一张纸对折之后和原来的纸型相似的比例。如果不是这样的比例,比如4:3,那我们就会发现对折后,纸的形状失真,变成3:2了。2、其实满足这个比例,可以有其他数值,如282mm×200mm,或者其他大小。然而210mm×297mm这个数值与A4的4有关,由于A0纸的大小为841mm×1189mm,A4纸就是A0纸折叠4次的大小。参考资料来源:百度百科-A4纸

一般A4纸张的尺寸是多少?

A5纸张的尺寸148×210mm 。A6纸张的尺寸105x148mm。A7纸张的尺寸,74x105mm。B5纸张的尺寸176x250mm。B7纸张的尺寸88x125mm。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841mm×1189mm,幅面面积为1平方米;B0的幅面尺寸为1000mm×1414mm,幅面面积为2.5平方米;C0的幅面尺寸为917mm×1279mm,幅面面积为2.25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;B0纸张亦按此法对开至B8规格。A0~A8和B0~B8的幅面尺寸见下表所列。其中A3、A4、A5、A6和B4、B5、B6七种幅面规格为复印纸常用的规格。扩展资料:纸张的规格是指纸张制成后,经过修整切边,裁成一定的尺寸。过去是以多少“开”(例如8开或16开等)来表示纸张的大小,如今我国采用国际标准,规定以A0、A1、A2、B1、B2......等标记来表示纸张的幅面规格。标准规定纸张的幅宽(以X表示)和长度(以Y表示)的比例关系为X:Y=1:n。许多国家使用的是ISO 216国际标准来定义纸张的尺寸,此标准源自德国,在1922年通过,定义了A、B、C三组纸张尺寸,其中包括知名的A4纸张尺寸,参考资料:百度百科-纸张尺寸

4a照片尺寸是多少厘米

标准4A纸规格为21*29.7cm(210mm×297mm)。A组纸张尺寸的长宽比都是√2:1,然后舍去到最接近的毫米值。A0定义成面积为一平方米,长宽比为√2:1的纸张。接下来的A1,A2,A3……等纸张尺寸,都是定义成将编号少一号的纸张沿着长边对折,然后舍去到最接近的毫米值,B组纸张尺寸是编号相同与编号少一号的A组纸张的几何平均。在A系列纸中,前面序号的纸対裁后,可以得到两张后面序号大小的纸,比如A0对裁后可以得到2张A1,A1对裁可以得到2张A2,依此类推,A0,A2,…,A5,所有尺寸的纸张长宽比都相同。A号纸实际是一批大小不一的纸张,它后面携带的编号可以理解为相互对折的次数,而A4纸实际上就是A0纸第四次对折的纸张大小,所以给了它一个看上去学术而且直白的名字——A4。扩展资料A4尺寸最初来源;科学家经过了一番积累,找到了一个比例,而这个比例在随后的一个世纪里面,改变了我们熟悉的这个世界,在这些黄金比例中,唯独有一个比例特别引人注目,它就是1:1.414优势在哪里,1:1.414是最适合于标准化纸张型号的比例。以A0到A6这个区间来说,A0=841x1189mm 面积正好是1平方米,不断将长边对折分割并且不会改变原来的比例关系,而且在大量的生产过程中不会造成任何的纸张浪费,当A4对折就会产生A5,虽然整数好记忆,但是它不能被近似值5:7 也就是1:1.4所替代。因为按照对折来计算会出现误差,那就会带来一大堆复杂的比例计算问题,而A号纸的运用,不会带来任何计算问题,它在工厂的剪裁中可以做到最大程度的避免浪费, 甚至是完全没有浪费,有着极为强大的功能性,而传统美学上沉淀下来的黄金比例1:1.618的分割以及其它的纸张比例就无法满足这一属性。参考资料百度百科--A4纸

a4尺寸是什么?

a4尺寸是1、a4纸是一种比较常见的纸张大小,它是由国际标准化组织的ISO 216定义的,具体规格是21*29.7cm,也就是210*297mm。2、ISO 216定义了A、B、C三组纸张尺寸,a4纸属于A组纸张,它的尺寸长宽比是√2:1,具体大小为297*210毫米。A系列的制定基础首先是求取一张长宽比为√2且面积为1平方米(m2)的纸张,这张纸的宽长分别为841毫米和1189毫米,被称作a0,在进行一次又一次对折的时候,将分别得到a1、a2、a3、a4的纸张尺寸。在制定标准时,尺寸均以整数为准,因此对切的纸张尺寸若带有小数(小于1毫米)则会舍入计算,具体如下(单位毫米):a4纸尺寸:210×297;a3纸尺寸:297×420;a2纸尺寸:420×594;a1纸尺寸:594×841。A4纸是由国际标准化组织的ISO 216定义的,规格为21*29.7cm(210mm×297mm),世界上多数国家所使用的纸张尺寸都是采用这一国际标准。这个标准最初是被魏玛共和国在1922年纳入DIN(编号是DIN 476),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。ISO 216定义了A、B、C三组纸张尺寸。C组纸张尺寸主要使用于信封。

A4纸张大小怎么计算?

最标准的各种纸张尺寸,比如A0A1A2A3A4的各种尺寸都有记录。A0=1189*841A1=841*594A2=594*420A3=420*297A4=297*210单位是毫米国家规定的开本尺寸是采用的国际标准系列,现已定入国家行业标准GB/T 1999内在全国执行。书刊本册现行开本尺寸主要是A系列规格,有以下几种:A4(16k)297mm×210mm;A5(32k)210mm× 148mm;A6(64k)144mm×105mm;A3(8k)420mm×297mm;注意:其中A3(8k)尺寸尚未定入,但普遍用。我们日常生活中说说的A4复印纸,8K纸就是指这些尺寸,即A4纸(16K纸)的尺寸为:297mm×210mm,32K笔记本(A5笔记本)规格为:21cm × 14.8cm。纸张尺寸介绍:a2纸的尺寸(大4开) 594mm×420mma3纸尺寸(大8开) 420mm×297mma4纸尺寸(大16开) 297mm×210mmb4纸尺寸(16开)b5纸的尺寸(32开)8开纸尺寸纸张按种类可分为新闻纸、凸版印刷纸、胶版纸、有光铜版纸、哑粉纸、字典纸、地图纸、凹版印刷纸、周报纸、画报纸、白板纸、书面纸、特种纸等。普通纸张按克重可分为60gsm、80gsm、100gsm、105gsm、120gsm、157gsm、200gsm、250gsm、300gsm、350gsm、400gsm。8开就是8开的,尺寸是390X270mm,要是word里面没有,那就自行设定。全开,载成8张,你量一下.纸张的规格是指纸张制成后,经过修整切边,裁成一定的尺寸。过去是以多少"开"(例如8开或16开等)来表示纸张的大小,现在我采用国际标准,规定以A0、A1、A2、B1、B2......等标记来表示纸张的幅面规格。标准规定纸张的幅宽(以X表示)和长度(以Y表示)的比例关系为X:Y=1:n 。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841mm?189mm,幅面面积为1平方米;B0的幅面尺寸为1000mm?414mm,幅面面积为2.5平方米;C0的幅面尺寸为917mm?279mm,幅面面积为2.25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;B8纸张亦按此法对开至B8规格。A0~A8和B0~B8的幅面尺寸见下表所列。其中A3、A4、A5、A6和B4、B5、B6等7种幅面规格为复印纸常用的规格。

Describe the basic characteristics of cash flow used in the valuation of an investment. What are the main principles used to determine cash flow?  The cash flows in the valuation of the investment are incremental cash flows,the changes in cash flows that will occur if the projects is undertaken.  The main principles used to determine cash flow involves:  <1>Decisions are based on cash flows,not accounting income.  <2>Cash flows are based on opportunity cost which is a firm"s loss by undertaking the project.  <3>Determining the cash flow decisions account for the time value of money.  <4>Cash flows are analyzed on an after-tax basis.  <5>Financial costs are reflected in the project"s required rate of return.  Describe how NPV is calculated and describe the information this measure provides about a sequence of cash flows. What is the NPV criterion decision rule? Why is NPV considered to be a superior method of evaluating the cash flows from a project?  <1> The following procedure may be used to compute NPV:  Identify all costs(outflows) and benefits (inflows) associated with a project ;  Determine the appropriate discount rate for the project;  Find the PV of each cash flow using the appropriate discount rate;  Compute the NPV for summing up the discounted cash flows.  So the mathematical formula is NPV=  Inflows are positive nd increase NPV because it illustrates the benefit associated with the projects.Outflows are negative and decrease NPV because it illustrates the cost associated with the projects.  <2>The NPV criterion decision rules are summarized:  Accept projects with a positive NPV which will increase shareholder wealth.  Reject projects with a negative NPV which will decrease shareholder wealth.  When two projects are mutually exclusive , the project with the higher positive NPV should be accepted.  <3>NPV is a superior method of evaluating the cash flows from a project because of 3 reasons:  NPV uses the cash flow instead of the earnings.  NPV uses all the cash flows of the project and don"t ignore the cash flows beyond a particular date.  NPV discounts the cash flows properly and considers the time value of money when handling cash flow.

六年级英语小写作文怎么写

1. 六年级英语作文怎么写啊,急,急 英语写作是语言应用的一个重要方面,也是语言能力测定的重要手段,衡量写作水平的标准便是看其是否能用学过的语言材料,语法知识等用文字的形式来表达描述。 书面语言表达一般分为三个过程:思维、组织、表达。先是思维,把要写的东西在脑中思考,这往往是个别的,孤立的一些素材,很凌乱琐碎;因此要对此进行组织,把这些思维作出整理,使其条理、系统化,但这还是较粗糙的,可能还有一些用词不当或语言错误;最后才是表达,把组织过的材料仔细推敲,确无问题了再落笔成文。在撰写时要注意主谓语一致,时态呼应,用词贴切等,这就是写作。上述的三个过程,最难的就是第三个过程,这需要我们有较好的语法知识,掌握一定数量的句型,习惯用语,熟练的写作技巧,这样才能写出通顺生动的文章来。 总之,要提高英语写作水平,需要两方面的训练:一是语言基础方面的训练,要有扎实的造句、翻译等基本功,即用词法、句法等知识造出正确无误的句子;二是写作知识和能力方面的训练以掌握写作方面的基本方法和技巧。 那么,究竟怎样才能写好作文呢? 阅读优秀范文 首先要搞好阅读。阅读是写作的基础,在阅读方面下的功夫越深,驾驭语言的能力也就越强。所以要写好英语先要读好英语,在语言学习方面狠下苦功,教科书要读透,因为教科书中的文章都是一些很好的范文,文笔流畅,语言规范,精彩的一些课文段落要背诵。再就是要进行大量课外阅读,并记住一些好文章的篇章结构。 加强练词造句训练 其次,要加强练词造句的训练。词句对作文相当于造房的材料,无好材料就造不出好房子。平时在学习阅读时要注意收集积累,把好的词语、短语、句型做好笔记。平时在练习中的错误也要做好记录,再对照正确句子,使地道的英语句子如同条件反射,落笔就对。 了解英语写作格式 还有,要了解英语写作的不同体裁与格式。可以先看一本介绍英语写作入门的书,对英语写作有一个初步的概念,如怎么写议论文,如何提出论据,如何展开,如何确定中心句;又如,英语信的格式,如何根据不同身份写不同结束语等,然后根据不同的体裁进行写作练习。 用英语写日记 要养成记英语日记勤练笔的好习惯。经常用英语记日记,等于天天在练笔,这无疑是提高英语协作的行之有效的好办法。在记日记时,不要总是用简单句,要有意识地用一些好的词组、句型、关联词和复合句等,使文句更优美生动。还有要按照题目或所给情景写文章练笔。写好后对照范文,找出差距,然后再练习,这对提高英语作文也很有帮助,在游泳中学会游泳,只有多练习才能练好。 总之,平时学习语言素材积累多了,体裁格式记住了又经常练习不断提高,到作文下笔时就会得心应手,水到渠成。 2. 六年级英语小作文 My favourite festival My favourite festival is Spring festival.Because it no school and has some partys.I can get lucky money during the Spring festival.And I can play with my friends or go sightseeing with my parents.I can eat a lot of delicious foods.And I can play fun. 3. 小学六年级英语作文,带翻译 随便写下,字数不要很多 Dear Daming: Thanks for your last letter,you asked me what I often do ,well,I like singing,I often sing at home,sometimes when it"s hot, I went swimming,and on weekends I often ride my bike to the park ,I do a lot of thing there with my friends,I play basketball and play football.I never play the piano or dance ,because I can"t. 谢谢你的上封信,在信中你问我我经常做的事情,我喜欢唱歌,我经常在家里唱歌,有时天气热,我出去游泳,在周末,我经常骑车去公园,我和我的朋友在那 做很多事情,打打篮球啊,踢踢足球啊,我从不弹琴或跳舞,因为我不会。 又重写了一篇。 4. 六年级英语日记怎么写 Though my daily life is extremely monotonous, I try hard to adapt myself to it.

I go to school at seven o"clock. After school is over, I return home. We usually have supper at seven o"clock.Then I begin to do my homework. I want to finish it before I go to bed. 虽然我的日常生活十分单调,但我却竭力设法去适应它。为什么?因为我打算做一个好学生,希望将来为国家服务。 我每天六点起床、洗脸刷牙后,就开始复习功课,七点钟我就去上学。 放学后,我就回家了。我们通常在七点钟吃晚餐,之后我就开始做家庭作业,希望在睡觉前把它做完。 5. 小学六年级英语作文怎么写不限题材60个单词~~~~~急谢谢了 介绍家人的 hi !l am xx,l am elue.here is a photo of my family.There are my grandparents.my grand mother is xx she is 70.my grandfather is xx.he is my 70 too .this is my mother.she is 35.and this my fathe.he is36.the boy is my brother.he is 10 .we are in xx primary school(小学).l love my family 这是我自己写的,你写英语时注意,每句开头都要大写,由于时间关系我就不大写了 那个格式比较乱哈,凑活看看。看在深夜帮你解答就采纳吧。 6. 六年级上册第一单元的英语作文怎么写 I am in primary school now, I have many lessons to learn from Monday to Friday, my favorite subject is English.
