本文进一步研究了函数项级数的逐项积分定理。

In this paper, the theorems of term-by-term integration have been studied further.

其次，将逐项积分结果求和并证明了求和结果与传统直接积分法的塑性功率表达式相同；

Then, sum of the termwise integrated results is proved to be equal to that obtained from traditional immediate integration for plastic deformation power.
