We give a simple method of partitioning a true fraction into the partial fraction expansion.

给出了把真分式分解为部分分式之和的一个简便方法。

Since you often won't get numbers which exactly match the desired ratio, you could do a continued fraction expansion of their quotient.

因为你往往不会得到数完全正确比赛所需的比例，你可以做一个连分数他们的商展开。

This paper gives a practical algorithm for partial fraction expansion of a rational function with multiple poles without derivative evaluation.

对具有多重极点的有理函数，本文给出了部分分式展开的实用算法，该算法不需求导数值。

This theory holds that in its early history, the observable Universe underwent a period of exponential expansion, doubling in size many dozens of times, growing our observiball a tiny fraction of the size of an atomic nucleus to that of, say, a beach ball.
