It is the distance between atoms corresponding to zero potential energy.

这就是相应于势能为零时的原子间距。

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary.

你知道，如果你想测量重力场，中某种东西的势能，你需要，在某处定义一个零点，对吧？

We have defined potential energy 0 to be zero at infinity, and that is why all bound orbits have negative total energy.

我们规定，无限大时,势能为，这就是为什么所有的,规则轨道总能量为负。

youdao

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.

你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。

Energy is NOT limited, when we examine the potential of zero-point energy couple with models of broken parity, energy is infinite in scope.
