When the mathematician would solve a difficult problem, he first frees the equation of all incumbrances, and reduces it to its simplest terms.

当数学家要解决一个难题时，他首先会释放方程中的所有障碍，并将其简化为最简单的项。

John doesn't find me interesting any longer, so he leaves his faded wife and goes to see his pretty neighbor, who has no incumbrances.

约翰不再觉得我有趣了，所以他离开了他褪色的妻子，去看望他没有负担的漂亮邻居。

A long minority, which, in the present times, so frequently disburdens a great estate of all its incumbrances, and restores the family to their ancient splendour, could in those times have no such effect.

一个长期的少数派，在当今时代如此频繁地卸下巨大财产的所有负担，并使家庭恢复到古代的辉煌，在那个时代可能没有这样的效果。
