Based on the Lagrangeformula with constants variables, some new sufficient conditions for ensuring globally exponential stability of such systems are derived.
基于拉格朗日常数变易法，给出这类系统全局指数稳定的一个充分条件。

The improved formula not only has the more simple form for the derivation of the function, but also much less computer time than the Lagrange method.
