摘要：

This paper is concerned with the number of limit cycles of pla-nar piecewise linear systems for improper node-improper node and improper node-node types with a straight line of separation. We obtain some sufficient conditions for the existence and stability of limit cycles and prove that the systems have at least two nested limit cycles in some parameter regions.
