why open a school全文翻译

When I opened Mott Hall Bridges Academy in 2010, my goal was simple: open a school to close a prison. Now to some, this was an audacious goal, because our school is located in the Brownsville section of Brooklyn -- one of the most underserved and violent neighborhoods in all of New York City. Like many urban schools with high poverty rates, we face numerous challenges, like finding teachers who can empathize with the complexities of a disadvantaged community, lack of funding for technology, low parental involvement and neighborhood gangs that recruit children as early as fourth grade.1:03So here I was, the founding principal of a middle school that was a district public school, and I only had 45 kids to start. Thirty percent of them had special needs. Eighty-six percent of them were below grade level in English and in math. And 100 percent were living below the poverty level.

Wolf!" and when his neighbors came to help him, laughed at them for their pains.一个牧童,在一个村子的边上放羊,他三番四次地喊“狼来了”,村民听到后都跑出来帮他,但其实狼并没有来,牧童只是拿他们来开玩笑。 The Wolf, however, did truly come at last. The Shepherd-boy, now really alarmed, shouted in an agony of terror: "Pray, do come and help me; the Wolf is killing the sheep"; but no one paid any heed to his cries, nor rendered any assistance. The Wolf, having no cause of fear, at his leisure lacerated or destroyed the whole flock.不过,狼,最后真的来了。这时,牧童真的着急了,他非常害怕地叫喊:“求求你们了,过来帮帮我吧,狼正在吃羊了”,但没有人理他,更没有人来帮他。结果,那只狼肆无忌惮对羊群大开杀戒,羊群一下子就全毁了。 There is no believing a liar, even when he speaks the truth.这故事告诉我们:撒谎的人是没人相信的,即使当他说实话的时候。

英语a school librarian怎么翻译?

a school librarian学校图书馆员

work in a school什么意思中文

你好,解释为在学校工作

a school picture 对吗

a picture of school

at a school是什么意思

这是不定冠词与定冠词的差异.a(an)或者什么都不加,都是不定冠词,the定冠词.英语中的不定冠词与定冠词实则与中文里的虚指和实指有异曲同工之妙. 不定冠词是虚指,如I work at a school.这里虚指我在一家学校工作,甚至你可以译为我是一名教员.强调的是你的工作范围或者说职业.比方说,初中有段最通俗的对话如下: Wei Fang:Hello,Li Ming Li Ming:Hello,Wei Fang Wei Fang:Let"s go to school Li Ming:All right 注意,这里的Let"s go to school,school前没没有加词,是不定冠词,虚指,标准译为:我们上学去吧.指的是我们上学这件事,并不强调是去哪家学校. 而I work at the school 是实指,特指我在那所学校工作(一般前文已经提及那所学校了,比方说XX school),强调的实际工作的那所学校场所.

at school和in school的区别是什么

at school和in school这两个短语有什么区别?请看下文。 区别是什么 at school这个短语作“上学”或“在求学”讲,相当于at- tending school的意思,和“在学校里”讲,相当于 on the school premises的意思; in school这个短语作“在学校”讲,是指场所,相当于 in the school building的意思,和“在上课时间”讲, 相当于 in lesson time的意思。 例如:She went out to do her shopping while the children went at school.在孩子们上学的时候,她出去买东西了。 He could not do his home work, as he found he had left his textbook at school.他发现他把课本丢在学校里,没法做家庭作业了。 Students are not allowed in school before 5∶30 a.m.早晨5点30以前学生不许进入学校里。 We did the first part of exercise in school,and the rest of homework.第一部分练习我们在上课时做,其余部分当家庭作业。 例句 ①I bet you were good at games when you were at school. 我敢说你上学时体育很棒。 ②Should our children be taught to swim at school? 我们的孩子应该在学校学习游泳吗? ③He teaches English in the school all the while. 他一直在这所学校里教英语。 ④She plays the flute in the school orchestra. 她在校管弦乐队里吹长笛。 相关句子 1、There is a subdued atmosphere in the school at exam time. 在考试期间,学校里有一种压抑的氛围. 2、Police are investigating the suspected drug ring at the school. 警方正在调查这所学校的可疑贩毒团伙。 3、Ordinarily she sleeps at the school and goes home only on Saturdays. 她平时住在学校,星期六才回家。 4、Connie did well at school and graduated with honours. 康妮在学校表现很好,以优异的成绩毕业了。 以上就是我整理的at school和in school这两个短语的区别,供参考!

钢管中sch 10s 是什么意思

呵呵这个代表钢管的压力,也就是对应的壁厚。

pcb、sch的文件用什么软件才能打开?

用电子设计软件PROTEL99SE 可以打开。

SCH 文件是什么

是电路原理图文件。可以用protel99 se软件打开。

德语中以sch为开头的国家的单词

Schweiz瑞士

德语发音求助:关于“ch”和“sch”发音的区别

ch在汉语里没有对应的音,一般情况下介于xi和hi这两个音之间,就是发hi的口舌头上抬一些,口腔紧一点,送气。ch在元音后面时发h的音。sch比较类似汉语拼音的sh,口再圆一点,舌头更卷。

阀门 法兰 sch是什么意思

定义  英文名称;Flange Gate Valve的启闭件是闸板,闸板的运动方向与流体方向相垂直,闸阀只能作全开和全关 , 不能作调节和节流。闸板有两个密封面 , 最常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异 , 通常为 50, 介质温度不高时为 2°52" 。楔式闸阀的闸板可以做成一个整 体,叫做刚性闸板;也可以做成能产生微量变形的闸板 , 以改善其工艺性 , 弥补密封面角度在加工过程中产生的偏差 , 这种闸板叫做弹性闸板。  闸阀的种类 ,按密封面配置可分为楔式闸板式闸阀和平行闸板式闸阀 , 楔式闸板式闸阀又可分为:单闸极式、双闸板式和弹性闸板式;平行闸板式闸阀可分为单闸板式和双闸板式。按阀杆的螺纹位置划分,可分为明杆闸阀和暗杆闸阀两种。本类阀门在管道中一般应当水平安装。  闸阀关闭时 , 密封面可以只依靠介质压力来密封 , 即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封。大部分闸阀是采用强制密封的 , 即阀门关闭时,要依靠外力强行将闸板压向阀座 , 以保证密封面的密封性。  闸阀的闸板随阀杆一起作直线运动的,叫升降杆闸阀 ( 亦叫明杆闸阀)。通常在升降杆上 有梯形螺纹,通过阀门顶端的螺母以及阀体上的导槽,将旋转运动变为直线运动 , 也就是将操作转矩变为操作推力。  开启阀门时,当闸板提升高度等于阀门通径的1:1倍时,流体的通道完全畅通,但在运行时,此位置是无法监视的。实际使用时,是以阀杆的顶点作为标志,即开不动的位置,作为它的全开位置。为考虑温度变化出现锁死现象 , 通常在开到顶点位置上 , 再倒回 1/2-1圈 , 作为全开阀门的位置。因此 , 阀门的全开位置,按闸板的位置(即行程>来确定。  有的闸阀 , 阀杆螺母设在闸板上,手轮转动带动阀杆转动 , 而使闸板提升 , 这种阀门叫做旋转杆闸阀或叫暗杆闸阀。

管道sch壁厚是根据什么定出来的

  ASME B36.10M《焊接和焊接轧制钢管》和ASME B36.19M《不锈钢钢管》规定了管壁厚度号Sch5、Sch10、Sch20 、Sch40 、Sch80、Sch160和STD、XS、XXS,以及各管壁厚度号的具体钢管厚度数值。  美国标准中管道压力等级有:150Psi (CL150)、300Psi (CL300) 、400Psi (CL400) 、600Psi (CL600) 、900Psi (CL900) 、1500Psi (CL1500)、2500Psi (CL2500)。  1 Psi==1磅/平方英寸  =0.454Kg/(25.4mm)2=4.45N/645.16mm2=0.0069N/mm2=0.0069MPa    管壁厚度号是管子设计压力与设计压力下材料许用应力的比值乘以1000,并经园整的数值。  Sch=PX1000/[σ]T 如果是碳钢管,按ASTM A53,在室温下 屈服强度为:[σ]t=30000Psi=205MPa Sch=1200PsiX1000/30000Psi=Sch40 Sch=600PsiX1000/30000Psi=Sch20 Sch=300PsiX1000/30000Psi=Sch10 Sch=150PsiX1000/30000Psi=Sch5  在定义管壁厚度号时,把屈服强度等同了许用应力,按现在观点,许用应力仅为屈服强度的60%左右,这样提高了钢管设计中的安全系数。  在定义管壁厚度号时,将钢管壁厚仅取决于设计工作压力和许用应力,按现在观点,钢管壁厚与钢管外径有很大关系。从表1中看出ASME16.5的规定的实际设计工作压力和150Psi (CL150)、300Psi (CL300) 等压力等级数值换算而得的MPa压力值有很大的差别。从ASME B36.10或ASME B36.19标准的列表中所列实际壁厚数值和表2可以看出,在相同的钢管压力等级下,钢管外径愈大,钢管壁厚愈厚。钢管的壁厚数值与管壁厚度号Sch的名义数据不形成比例关系。因而,我们不能依据管道压力等级的Psi名义数值去直接对应管壁厚度号,不能直接由此确定钢管壁厚值。

sch40壁厚是多少

sch30这是壁厚系列,并不是单一壁厚,同一系列规定了在每种管径规格下的一套壁厚标准集合

2" sch. 40镀锌钢管,2" sch. 40是什么意思啊

SCH表示英制管壁厚系列:Sch.20----全称:Schedule 20Sch.10s--带s的系列为不锈钢专用,碳钢不用。举个例子:2" sch.10s 表示2”接管的壁厚为2.9mm,材质为不锈钢;2" sch.40 表示2”接管的壁厚为3.91mm。顺便再说一下钢管壁厚的表示方法:钢管壁厚表示方法有管子表号、钢管壁厚尺寸和管子重量三种方法 1)是以管子表号"Sch"表示壁厚。 管子表号是管子设计压力与设计温度下材料许用应力的比值乘1000,并经圆整后的数值。即: Sch=P/[σ]t×1000 ANSI B36.10壁厚等级:Sch10、Sch20、Sch30、Sch40、Sch60、Sch80、Sch100、Sch120、Sch140、Sch160十个等级; ANSI B36.19壁厚等级:Sch5s、Sch10s、Sch40s、Sch80s四个等级; 2)以钢管壁厚尺寸表示 中国、ISO、日本部分钢管标准采用 3)是以管子重量表示管壁厚度,它将管子壁厚分为三种: a.标准重量管,以STD表示 b加厚管,以XS表示 c.特厚管,以XXS表示。 对于DN≤250mm的管子,Sch40相当于STD,DN<200mm的管子,Sch80相当于XS
