摘要
通过对多元函数梯度的研究,给出了多元函数在梯度的模有界的情形下连续和一致连续性的2个定理,给出了求多元函数极值的一个方法,并举例说明该方法的有效性.
By studying gradient of several variables, provided two principles of continuity and uniform continuity under the conditions of several variables in gradient's modular. It also provided a method to obtain the extreme of several variables and furnished instances to prove its effectiveness
