查询词典 pendulum bob

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。

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。

At the same time, different control methods are used to implement the single inverted pendulum control.

同时，论文利用不同的控制方法来完成一级倒立摆的神经网络控制。

The assigned problem of INVERTED PENDULUM is a part of Lab Work of Control System.

这分派 的倒立摆的问题是一个控制系统的实验室工作的一部分。

Therefore,the research of the inverted pendulum has important engineering background and profound significance.

因此，倒立摆的研究不仅具有重要的工程背景，还有深刻的理论意义。

We stopped by the old fashion ice cream parlor Manhattan Beach Creamery for some refreshment. The "No Shoes, No Shirt, No Problem" sign on the wall epitomizes the beach lifestyle.

我们去商店区的一家老式冰淇淋店坐坐，墙上挂著「没鞋，没上衣，没问题」的牌子完全捕捉了海滩生活的随性及风格。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
