I have got to put that in because that is a repulsive energy and that is going to decrease the energy of the system.

我必须要说清楚,因为这是一个排斥能,这将要减少这一系统的能量。

So, this is the repulsive energy term.

所以，这就是排斥能。

Positive energy is repulsive, and negative energy is attractive.

正的能量值代表斥力，负的能量值代表引力。

The net energy is the sum of the repulsive and the attractive.

净能量是排斥能,和引力能的总和。
