摘　　要：将亚正定阵引入到V o lterra系统,获得了判定该系统在正的平衡态全局稳定、扇形稳定及关联稳定的另一些新方法.从应用情况看,本文方法是有效的而且更为实用.Subpositive definite matrix was leaded into Volterra systems, and some new criterions for Volterra systems on overall situation stability, Sector stability and connection stability were acquired. According to the application, these methods are valid and more practical.
