1·Among the basic arithmetic operations over finite fields, the computation of multiplicative inverse is the most time consuming operation.

在有限域的基本运算中，乘法逆元的计算是最费时间的运算。

2·Also, the multiplicative inverse is the reciprocal of any number, that is, multiplying the reciprocal of any number by the number itself will yield the multiplicative identity.

此外，乘法逆是互惠的任何数量，也就是乘以倒数任何数目的数量本身将产生倍增的身份。

3·This includes normal and generalized inverse eigenvalue problem which includes the additive, multiplicative classical inverse eigenvalue problems as special cases.

包括常义特征值反问题和广义征值反问题，这类问题包括加法和乘法经典代数特征值反问题。
