英文摘要：

Based on the qualitative theory of differential equations,a class of systems withmulti-molecular reversible biochemical reaction a second-order saturation gets further investi- gation, it is shown necessary and sufficient for the existence of unique limit cycles and global- ly asymptotic stability of the positive equilibrium of this system.
