摘要
从微分流形理论出发，讨论了Ｐｆａｆｆ形式的勒让德变换；引入了勒让德变换算子；给出了勒让德变换与偏微商的关系；证明了两个定理和一个引理．从而将勒让德变换的应用扩充到偏微商领域．
According to differentiable manifolds theory, the paper discusses tile Legendre transformation of the Pfaffian form, introdues the operator of the Legendre transformation, derives the relation between the Legendre transformation and the partial differentiation and proves three laws. Therefore, the applied boundary is expanded into the spilers of the partial differentiation, which offers the convenience for the partial differential operation.
