查询词典 conical pendulum

Is it true that there's a huge pendulum in the middle of Hogwarts grounds?

在Hogwarts平面图的中央有一个巨大的钟摆，那是真的吗？

Or maybe it was the pendulum that hypnotize me.

也许是反复来回的钟摆将我催眠了吧。

The YZ-CCD type automatic hypsometer can work together with other CCD deformation instruments, such as the pendulum system, settlement system and deflect meter.

而且传高仪也可以很方便地与CCD型垂线仪、静力水准仪、引张线仪等仪器连成一个自动化变形监测系统。

In this paper, imaging method based on pendulum module is proposed for dealing with these problems.

针对这种情况，提出了一种基于钟摆模型的成像方法。

Moment of inertia ; Product of inertia ; Dynamic balance ; Measurement Method ; Missile ; Torsion pendulum

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。

He paid $5,000 for this cupcake.

他我这个纸杯蛋糕花了5000美元。

I mean, if you want to, that is

我的意思是，如果你们想吃的话。
