精美的艺术品不像实用艺术品那样受物理定律的约束。

Fine-art objects are not constrained by the laws of physics in the same way that applied-art objects are.

因此，对物理定律的敏感性是应用艺术作品创作者的一个重要的考虑因素。

Sensitivity to physical laws is thus an important consideration for the maker of applied-art objects.

Now the first law is going to hold in all of these steps, and we're going around in a cycle.

现在热力学第一定律,就蕴含在这所有的步骤里了，我们沿着这个循环走。

And that's also how people find ways to break the second law, because somehow they've messed up on what their system is.

这就说明了某些人是如何想到办法,“打破“第二定律的，因为他们以各种方式搞错了,他们的系统的定义。

And so this is really a mechanical term, if you like, and this is electrostatic or coulombic.

所以说这真算是一个力学问题，你愿意的话，也可以说它是,静电学或库仑定律方面的问题。
