典型同源A-I模型的整体解

Global solution for typical A I model with common sources

利用比较定理及上下解方法，首先给出了典型的同源Ａ－Ｉ模型解的下界估计，再由能量积分方法和Ｇｒｏｎｗａｌ不等式得到了解的先验估计，并结合“反馈”技巧证明了典型的同源Ａ－Ｉ模型整体解的存在性．

By the comparison theorem and monotone method, the lower bound is first given for the solution of the typical A I model with common sources, and energy integral method is used to obtain aprior estimate. The global existence for the solution of the model is then proved.
