But too large a grouping lacks "like-mindedness" and results in shallow integration with large exclusion lists.
但过大的分组缺乏“志同道合”，导致大扩展名单却只有不多的整合措施。
An improvement was made in grouping to find the integrating factors, so that those for some differential equations will be worked out mainly by integration.
本文对用分组法求积分因子做了一些改进；从而使一类微分方程的积分因子，主要通过积分的运算就可以得到。
