摘　　要：在一元复合函数求导法和多元函数求偏导的基础上,通过恰当合理的知识变式、题目变式、思维变式、方法变式,有意识的启发、引导学生沿着预期的目标进行积极地思维,概括出各种问题中共同的、本质的求导方法及规律,使得很多复杂的多元复合函数求导问题得以简化。On the basis of the derivation of mono-composite function and the partial derivation ot the complex multi-function, through appropriate and rational variant of knowledge, variant of themes, Variant of thinking and methods inspiring and guiding the students have a positive thinking. To summarize common and natural derivation methods or laws in vary of situation, and make a simplified derivation methods of the composite fuction.

关 键 词：多元复合函数 求导 变式
