By calculating, it can be found that the potential energy in magnetic field is different from the normal potential energy, it is a function of both coordinates and time.

通过计算发现，磁场中的势能不同于通常意义的势能，它既可以是位置坐标的函数，也可以是时间的函数。

The results are as follows:1)The chief contributions of the normal potential field are mainly concentrated at the long quasi-stationary waves and show significant seasonal variations.

主要结果如下： 1 位势场的高度主要贡献，集中在准静止长波范围内，并具有明显的季节变化。
