It is exemplified that, with a credible error estimation, their performances are superior to the frequently-used one, which determine internal inductance via the vector magnetic potential.
实例计算表明这两种新算法的性能优于常用的通过磁矢势求解内电感的算法，并能得到可信的误差估计。

This method being complicated can only approximately estimates the value of static inductance, and the error is rather big.
这种方法计算比较繁琐，只能近似估计静态电感值，误差较大。

In this paper a new digital inductance tester is designed, its circuit principle and components used in the tester are described, and error analysis is given.
