摘要	本文的主要目的是研究一类带奇异权函数的椭圆方程组。通过运用锥上的不动点指数定理，我们得到了该类椭圆方程组在不同参数区间内正径向解存在性、多重性和不存在性的新结果。
Abstract	The goal of this paper is to study a class of elliptic systems with singular weight function. By using the fixed point index in a cone, we derive new results for the existence, nonexistence and multiplicity of positive radial solutions to this class of elliptic systems in different parameter intervals.
