| 摘 要： | 对于数学分析教材中所讲到的求解多元函数的偏导数的方法，大家都很熟悉，但是在遇到比较复杂的函数形式时，求偏导数的复杂程度也会随着增加。这时可以由偏导数的定义得到一种估计形式，而本文采用统计的方法对此问题给出了另外一种估计形式，最后通过例子对两种估计进行比较。

| Abstract: | We are familiar With the algorithm of the partial derivatives from the calculus. But the algorithm will become more complicated when the function is more complicated. Of Course, a kind of estimate can be obtained from the definition of the partial derivatives. The paper gives another algorithm using the designs of experiments. At last, the two estimate forms are compared by an example. |
