转动

In the four-cycle engine, every two revolution s of the crankshaft produce one revolution of the camshaft and one opening and closing.

在四行程发动机中，曲轴每转动两圈，凸轮轴转动一圈，使气门开启和关闭一次。

We first play galloper. The galloper here is very special. It is divided into upper and lower layers, which can rotate in the same direction, or in the opposite directions. Riding in such a galloper is just like living in fantasy scenes, which is really seductive.

我们首先去玩旋转木马，这里的旋转木马很特别，分为上下两层，可以同方向转动，也可以反方向转动，骑在这样的旋转木马上，就好像身处梦幻场景，实在是太令人向往了。

For seventy－ five years,Signor Seguso had stood in front of a blazing hot glassworks furnace——ten,twelve,eighteen hours a day——holding a heavy steel pipe in his hands,turning it to prevent the dollop of molten glass at the other end from drooping to one side or the other,pausing to blow into it to inflate the glass,then laying it across his workbench,still turning it with his left hand while,with a pair of tongs in his right hand,pulling,pinching,and coaxing the glass into the shape of graceful vases,bowls,and goblets.

这75年间，瑟谷梭先生每天在玻璃厂熊熊的熔炉前站上10个、12个或18个小时，两手握着铁管不停转动，以免另一头那团熔化的玻璃流向一侧，又得不时停止转动，朝着铁管吹气。然后把铁管横放在工作台上，左手还在转，右手拿着一把钳子不住地拉捏，巧妙地将玻璃弄成雅致的瓶子、碗钵和高脚杯形状。

Herons came, with a great bold noise as of opening doors and shutters, out of the boughs of a plantation which they frequented at the side of the mead; or, if already on the spot, hardily maintained their standing in the water as the pair walked by, watching them by moving their heads round in a slow, horizontal, passionless wheel, like the turn of puppets by clockwork.

一群苍鹭高声大叫着飞来，那叫声就像开门开窗户的声音，它们是从草地旁边它们常常栖身的树林中间飞来的；或者，如果它们已经飞到了这儿，它们就坚决地停在水里，像一些安装有机械装置的木偶转动一样，缓慢的、水平的和不动感情地转动着它们的脖子，看着这一对情人从它们旁边走过。

Mechanical inertia identification method was deduced from the current model and the mechanical model of the PM motor.The gain of the speed controller was obtained through the mechanical inertia,a group of controller gains obtained through several turns of identification.

首先通过电机电流和电压方程以及运动方程推导出转动惯量的计算方法，再根据系统的转动惯量计算出速度控制器参数，在进行多次辨识和计算后，可以得到一组速度控制器参数。

Inertial mass and moment of inertia of inertia are used, but they are different physical quantities, there is no secondary school physical moment of inertia term may be not to mention the difference between the two.

惯性质量和转动惯量都用来表示惯性，但它们是不同的物理量，中学物理不出现转动惯量的名词，可不必提两者的区别。

A handle (43) is provided on the intermediate post (39) at the left surface (36) of the machine enclosure, which is a ingathering handle rotating between the containing device on the outer surface of the machine enclosure body (31) and the holding position protruding from the machine enclosure body (31) outer surface to the outside.

扶手(43)是能够在沿着机壳主体(31)的外表面的收容位置以及从机壳主体(31)的外表面向外侧突出的把持位置之间转动的收纳式扶手，即使在门(32)关闭的状态下，通过将扶手(43)转动到把持位置，在从构成机壳主体(31)的外表面的中间支柱(39)的外表面向外侧突出的状态下也能把持扶手(43)，并且通过将扶手(43)收容在收容位置，而能够收容在与门(32)的外面相比更靠近内侧的位置。

This paper introduces the inverse spectrum and its features ,and presents with some applied experimental examples in the rolling bearing analysis by using this method.

转动轴承故障的倒频谱分析张文苑周湛学刘国众摘要：先容了倒频谱及其特点，列举了其在转动轴承分析中的应用实例。

What is a...-jackhammer me! jackhammer me!

怎么弄 -转动我转动我

Objects are compared with the rotational inertia, but it said with the first law of inertia is not the same thing, it's the size of the moment of inertia.

物体相对于转动也有惯性，但它跟第一定律所说的惯性不是一回事，它的大小为转动惯量。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
