The design of the device using NC Lathe CA6240 control, part of the main transmission system using AC spindle motor and graded by the pulley driven spindle gearbox, through the inverter and gearbox to achieve sub; Feed System used by stepper motor driven ball screw slowdown after campaign vertical feed system through a gear after the ball screw drive, in the horizontal feed system through two gear-driven ball screw; Tool to automatically transfer tool carrier (4-position), thus achieving automatic tool change; by MCS-51 series 8051 data to be dealt with.

本设计利用数控装置对CA6240普通车床进行控制，主传动系统部分采用交流调频主轴电动机经带轮及分级齿轮变速箱驱动主轴，通过变频器和齿轮变速箱实现分段无级变速；进给系统采用步进电机通过减速后驱动滚珠丝杠运动，在纵向进给系统中通过一级齿轮减速后驱动滚珠丝杠，在横向进给系统中通过二级齿轮减速驱动滚珠丝杠；刀架改为自动转位刀架从而实现自动换刀；通过MCS-51系列8051单片机对数据进行计算处理，由I/O接口输出步进脉冲信号控制进给速度和行程；为了保持切削螺纹的功能，要在主轴外端或其它适当部位装上脉冲发生器；将车床的手动尾座改造成为可控电动尾座。

So it turns out that the Boltzman distribution law is only the first order approximation of the Bose or Fermi distribution. We can say it is the latter that is the general distribution law of ideal gas particle in a potential field.

由此可以证明玻耳兹曼分布规律只是玻色和费米分布规律的一级近似，所以后者才是处在势场中理想气体粒子的一般性的分布规律。

Existing professional employees in more than 40, they have years of experience in the advertising industry, has reached a high standard of business, the general manager and chief executive officer of designers already have a qualification.

现有各类专业从业人员40余名，他们都具备多年的广告业工作经验，已达到了较高的业务水准，总经理兼首席执行官已具备一级设计师资格。

He took her hand and held it genially.

Geobiology is the 1st order interdisciplinary study between geosciences and biosciences. It studies one of the three basic processes of the earth system, the biological process, which is the interaction between biosphere and other spheres of the earth.

地球生物学是地球科学与生命科学交叉形成的一级学科，它研究作为地球系统三大基本过程之一的生命过程，即生物圈与地球其他圈层的相互作用。

The continue stage go higIT or get the Apollo into orbit round the earth.

最后一级火箭升得更高，把"阿波罗号"送进围绕地球运行的轨道。

The windows winked and the flight of stone steps glared in the sunlight, the prim garden walks were so freshly gravelled that they gave a sandy, gingery aspect to the place, reminding one unpleasantly of red hair.

窗子闪闪烁烁，一级级的石阶在阳光里亮得耀眼，整洁的花园里的小径新铺了砂石，使这地方呈现出一种红里透着姜黄的面貌，使人想起一种令人不愉快的红毛红发来。

The cold event around 10900～10050, was corresponded to the Younger Dryas before the end of Late Glacial Period.

在晚冰期结束前，大约10900～10050aBP，是一个典型的冷事件，相当于Younger Dryas，其内部存在次一级干—湿波动。

Also I wouldn't mind seeing Glaive Throwers moved back to tier 2 (as the reason to move them to tier 1 in the first place was to stop tower rushes, now they are useless versus it), possibly improve Hippogryph Riders, improve Keeper of the Grove because now he's useless as first, second or third hero.

我不介意二级才能造弩车（它们本来在一级可以造是用来防止暴塔的，但是现在看来似乎一点用处都没有），而且要改进角鹰骑士，还有丛林守护者，因为他作为第一第二第三英雄都一无是处。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
