Abstract
According the theory of the singular point value and the calculating method, the highest singular point of the origin- 5th degree is obtained and proved for a class of cubic system.The problems of stability and integral condition of the origin are also solved.At the same time,the function of limit cycle bifurcation and the specific form with 5 cycles are created.
