It's no physics, it's pure math, and I'm not going to do that for you. It's some integral, and if the object is nicely symmetric, in general you can do that.
它纯数学，非物理，所以我不在这儿做，它是积分，若物体完美对称，你们基本都能做。
G. W. Leibniz Those few things having been considered, the whole matter is reduced to pure geometry, which is the one aim of physics and mechanics.
考虑了很少的那几样东西之后，整个的事情就归结为纯几何，这是物理和力学的一个目标。
This is called fluorescence, a phenomenon of physics and biology that borders on pure magic.
这叫做“荧光”，一种近乎纯魔术的物理学和生物学现象。
Since pure radioactive ion beam can be implanted into material directly, research on solid physics especially on impurity and defect in semiconductor become possible.
由于可以将纯净放射性核束注入到样品中去，使得其在固态物理特别是涉及到半导体中的杂质和缺陷问题的应用成为可能。
Similarly, on the pure logic analysis of the Archimedes Principle and Free Fall law, we could get an inevitable conclusion directly, which could help us better understand the laws of physics.
同样对阿基米德原理，自由落体问题等进行纯逻辑的分析，非常直接地得出了必然的结论，并且可以帮助我们更好地理解物理规律。
In physics based modeling, the object is viewed as a physics and not a pure geometry model.
基于物理的造型是将物体看成具有一定物理性质的形体，即某种物理模型而不是单纯的几何体。
