原先是简单的使用取模运算符（%）的实现，它非常低效，它自己检查从 2 到目标数的每个数字，确定是否是因子。

The original naive implementation used the modulus (%) operator, which is wildly inefficient, to check every number from 2 up to the target number itself to determine if it is a factor.

这些离散的值乘以整数，乘积因子,是普朗克常数除以2π,其中n可以取1，2，3，等等。

n It takes discrete values, multiples of some integer n, and the multiplication factor is the ratio of the Planck constant divided by 2 pi where n takes one, two, three and so on.

目前已有文献讨论过强子衰变过程对超子极化的影响，但这些文献中通常将衰变过程的极化转移因子取为一个常数。

At present, contributions to hyperon polarization derived from hadron decay have been argued, but in this argument decay polarization transfer factor is assumed as a constant usually.
