摘　　要：微分中值定理把函数在区间上的值的变化与导数联系起来,是利用导数研究函数整体性状最基本的理论依据,在数学中十分重要,内容极为丰富。以Rolle中值定理为例,把一元函数的Rolle中值定理推广到多元函数及向量值函数的情形,并进行了几何分析,最后通过实例阐述了Rolle中值定理在解题方面的应用。Differential mean value theorem it＇s the most basic theoretical basis to study connects changes of the function the overall character of functions values on the interval with derivative, by using derivative, and also very important in mathematics , and the content is extremely rich. In this paper, taking Rolle Mean - Value theorem as an example, and extends it to the case of multi - function and the vector - valued functions, and given geometric analysis, then elaborates the mean value theorem in solving problems by example.
