The other two methods are very simple, although they can give the atomic state of equivalent elections only by nonequivalent electrons.
另外两种方法，虽然要利用非等效电子的原子态才能给出等效电子的原子态，但方法简单。

The authors hold the view that international nonequivalent exchange is the exchange that is not based on international value or international production price.
本文认为，国际不等价交换是不以国际价值或国际生产价格为基础的交换。

Based on microstate generating function, a term generating function and atomic terms were obtained. The method is suitable for both equivalent and nonequivalent electronic configurations.
