自转

So the movement of wafer is consisted of planetary motion and spin motion.

使晶片的运动是行星运动和自转运动的合成运动。

Therefore, some measures have been taken, a rotation and a planetary motion are superimposed upon the tool electrode.

所以， 一些措施被采取了，自转并且一个星球运动被叠加在工具电极。

It is generally believed that Venus originated with the typical fast and direct rotation. But in the late evolution process, as a result of atmospheric tides and core-mantle friction inside the planet, the rotation is changed gradually. While some others considered that the change of Venus'rotation perhaps due to the early giant planetesimal's collisions.

一般认为，金星原来具有典型的快速正转的状态，在后来的演化过程中，由于潮汐作用或行星内部流体核与幔间的摩擦作用，使得自转逐渐发生变化；也有研究认为可能是早期受到大星子的偶然碰撞所致。

DESIGN FEATURES:"Strap-on" personal helicopter with contrarotating twin blades of tapered planform and fixed pitch (thus no autorotation capability - replaced by ballistic parachute, if desired).

设计特点："捆绑式"的俯视图的反向的锥形和固定摊位（因此没有自转能力双刀片个人直升机-由弹道导弹降落伞取代，如果需要的话）。

Because 1 day is against half of the time of the sun, this is the distance of self rotation of all 0 point and 1 point for one circle.

因为1日对着太阳的时间是一半，这是他所有0点和1点自转一周距离。

Take 0 point to 1 point as radius, and connect 0 point on sphere surface, and take radius as 3 R, calculate the volume, that is the distance of all 1 points self rotation for one circle.

以0点到1点为半径，到球体表面连接0点，取半径为3R，求这个体积。这是他所有1点自转一周距离。

IN THE 14 years since the first genetically modified crops were planted commercially, their descendants, relatives and remixes have gone forth and multiplied like profitable, high-tech pondweed.

自转基因首次走向市场的14年中，它们的后代、类似品种以及杂交品种不断出现并增多如可获利的高科技水池草。

Feb 25th 2010 | From The Economist print edition IN THE 14 years since the first genetically modified crops were planted commercially, their descendants, relatives and remixes have gone forth and multiplied like profitable, high-tech pondweed.

自转基因首次走向市场的 14 年中，它们的后代，类似品种以及杂交品种不断出现并增多如可获利的高科技水池草。

The theory of relativity also includes some more esoteric details, one of which is called spin precession.

相对论还包括一些更加深奥的细节，其中的一个被称作自转进动。

Compared with similar advanced equipment, FPP Series mill has advantages as follows,① Adding the cutting and grinding function;② Extend the time of material pressing and cutting and grinding;③ Solve the sensitivity of keeping the proportional spacing and proportional thickness;④ Widened material input size;⑤ Material output size are in a perpetual state;⑥ Multifunctional machine is used to dry and grind and filtrate material;⑦ Auxiliary equipment is less and covering is small and investment is small;⑧ Noise is low and dust is small, it is beneficial to protect environment and keep physical and mental health for operation workers.

FPP 型系列磨机的结构形式是电机拖动减速机带动磨盘旋转，带有压力的磨辊在磨盘上自转，对物料进行碾压，磨内的物料在旋转离心力的作用下均匀进入碾磨区，磨辊对物料实施挤压、剪切、研磨，故破碎能力大，粉磨能力强，与同类先进设备相比：①增加了剪切研磨功能；②延长了物料挤压剪切研磨时间；③解决了对物料粉层均匀一致，厚度一致的过于敏感性；④拓宽了对物料的进料粒度；⑤物料的出料粒度永远处于受控状态；⑥可以对物料进行烘干、粉磨、筛分一机多能化；⑦辅机设备少、占地小、投资省；⑧噪音小、扬尘点少，有利于环保和操作工人的身心健康。

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.

交际能力和语法的关系应该是目标与途径的关系。
