Abstract
It was studied the center conditions at the equator of a class of cubic polynomial system with no singular point at the infinity based on the method of a homeomophic transformation of the infinity into the origin(linear singular point).The first 18 singular point quantities were computed by Mathematica.At the same time,the conditions for the infinity to be a center were derived respectively.
