因子变换 meaning in Chinese

factor transformation

This dissertation introduces a regularization algorithm to tackle the problems of the nearly singular integrals . in the algorithm , the singular factor is removed from the kernel functions in the singular integrals by means of integration by parts
该算法通过对积分核进行一系列的分部积分，将引起几乎奇异积分的因子变换到积分号之外，从而可以克服几乎奇异积分的困难。
