The thesis presents an effective way to return market to shift dilemma between trade and environment through the contract linkage to environment negotiated and signed by both trade parties.

文章分析了环境联接合约签订的基础和作用,并对其条款进行了设计。

With the aid of MATHEMATICA, the direct reduction method was extended and applied in 2+1_dimensional variable coefficient generalized Kadomtsev_Petviashvili equation(VCGKPE).

借助于MATHEMATICA软件 ,将直接约化法推广并应用到 2 +1_维变系数广义Kadomtsev_Petviashvili(VCGKP)方程 ,获得了VCGKP方程的若干相似约化 ,其中包括PainleveⅠ型、PainleveⅡ型和PainleveⅣ型的约化

First, with the help of Mathematica,three kinds of reductions of MDWW equations areobtained by using direct reduction method.

借助Ｍａｔｈｅｍａｔｉｃａ，采用直接约化法获得ＭＤＷＷ方程的３种对称约化。
