摘　　要：讨论了拉格朗日中值定理证明中采用的各种辅助函数及其适用的教学对象,并为了使辅助函数的几 何意义更加明确,对其中的几何学角度出发建立的辅助函数作了改进。The article discusses different assistant functions used to prove lagrange Median Theorem as well as their applications in the course of teaching. To get assistant functions have more obviously geometric meaning. One of the functions, which is set up based upon geometry, has been improved.
