自转

Based on lots of video observation tests, there are three motion states of grinding medium in a mill tube, including projection, revolution and autorotation. The movement cycle of grinding medium departing from and contacting with the inner liner is equal to the vibrating period.

在对大量摄像实验反复观测和研究后发现：磨筒内的磨介存在抛射、整体回转和本身自转3种运动状态；磨介与筒壁的抛离与接触是沿着振动方向发生的，此过程是周期性的，其周期与振动周期相同。

What is called that the annulus of the inner cylinder executing a planetary motion is: the inner cylinder which can form the annulus is not only rotating by the axis of itself, but also rotating by the axis of the outer cylinder in the annulus.

所谓内管做行星运动的环空是指：构成环空的内管不仅绕其自身轴线自转，而且还同时绕环空外管的轴线公转。

The Geographic South Pole is where Earth's axis of rotation intersects its surface.

地理上的南极点是地球自转轴线与表面的交差处。

In spur gears the line of contact is parallel to the axis of the rotation; in helical gears, the line is diagonal across the face of the tooth.

在正齿轮联络线与自转的轴是平行的；在螺线齿轮，线横跨牙的面孔是对角的。

This is related to the axis of its self-rotation.

这是跟地球的自转转轴有关的。

A second factor is the rotation of the earth on its axis.

第二个因素是地球的自转在它的轴。

The intelligent tire that already developed a success has size to be like ice hockey, when pressure of the responsible tire that monitor and baric inadequacy, aerate for tire as motivation with wheel rotation.

已研制成功的智能轮胎有大小如冰球，负责监测轮胎压力及气压不足时，以车轮自转作为动力为轮胎充气。

Of a celestial body using two points on the surface of the earth as the earth rotates.

地球自转时在地球表面选择两点观察天体时产生的视差。

According to the celestial sphere on a different reference points to measure the Earth's rotation one week interval, there are three different "day" unit.

根据天球上不同的参考点来计量地球自转一周的时间间隔，存在三种不同的"日"的单位。

The nuclear force applying similarity's restrains inertial guidance way, the speed regulation carrying out commixture on the ion beam being unlike speed and the energy, develops the able ion allocating the fast direct-current transformer, is that cold nuclear fusion piles up, the nuclear engine and that kind nuclear power station start nuclear fusion and electric energy therefore the corollary equipment transporting systematic importance, combining to apply for a patent.

本发明项目特征是：在常温真空条件下，设置空间特定组合的电磁场，根据轻原子核固有的磁矩和内电场，先将两串待聚变的原子核约束在同一条线段内；再利用原子核固有的自旋动量矩矢量形成近光速自旋的超强力自转陀螺惯性制导特性，来克服库仑强势垒的偏向作用，实现直接对撞核聚变的；应用相似的核力约束惯性制导方式，对不同速度和能量的离子束进行混合调速，研制成的离子调速直流变压器，是冷核聚变堆、核发动机和该类核电站启动核聚变和电能输送系统的重要配套设备，所以合并申请一个专利权。

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。
