转动惯量；惯性积；动平衡；测量方法；导弹；扭摆

Foucault's pendulum, and other much more sensitive experiments, demonstrate that an inertial frame is also one in which the distant galaxies do not appear to rotate.

一节，我们介绍了惯性系的概念：找一个参考系使牛顿定律适用于傅科摆和其他更敏感的实验，而我们发现在这个惯性系中遥远星系是不转动的。

Newton precisely measured the inertial mass of a great many objects (what it took to get them moving, as in getting a pendulum started) and their gravitational mass (how fast they fell to the Earth), to determine that the two forces were equal, if not equivalent, and could be canceled out when doing physics.

牛顿精确测量了很多物体的惯性质量（使物体运动的内在动力，就像钟摆开始往复的动力）和它们的引力质量（以多快的速度向地表坠落），以此来确定这两种力是均等的，如果不均等，在做物理学运算时可能就会互相抵消。

If the pendulum is made of invar, the bob does not rise or fall much.

如果用不胀钢做钟摆，摆锤升降的距离就很小，这样无论夏季或冬季，钟''。

If the pendulum is made of invar, the bob does not rise or fall much. So the clock keeps good time in summer and winter.

如果用不胀钢做钟摆，摆锤升降的距离就很小，这样无论夏季或冬季，钟都走得很准。

There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums, since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从"invariable"一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

There are one or two exceptions. There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums , since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从"invariable"一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

First of all, this thesis analyses the structure and mathematic model of Inverted pendulum system.

本文首先对倒立摆系统的结构和数学模型进行了分析、建模。

The Inverted Pendulum is one of the most important classical problems of Control Engineering.

倒立摆是最重要最经典的控制工程问题中的一个。

This is a matlab inverted pendulum control of the paper, their use of fuzzy control method.

详细说明：这是一个matlab控制倒立摆的文件，其利用了模糊控制的方法。

It's not quite as simple as that.

并没有那么容易。

It debuted in 1992 in Japan and the United Kingdom, and 1993 in the United States.

它首次亮相于1992年在日本和英国，在美国1993年。
