摘　　要：研究了一类包含临界指数的椭圆问题.利用山路引理证明了拟线性椭圆方程非平凡解的存在性,并给出这个非平凡解的一个估计.In this paper,an elliptic equation involving the critical exponent is discussed. The existence of nontrivial solution for an elliptic equation is proved by virtue of mountion pass theorem. On the other hand,an estimate of a nontrivial solution is given, which plays an important role in the study of elliptic problems with critical Sobolev-Hardy exponents.
