二次式时滞差分系统的稳定区域

Stability Region of Quadratic Delay Difference Systems

初步建立了二次式时滞差分系统定量的稳定性理论，即在一定的条件下，不仅可以断言零解的一致稳定性和一致渐近稳定性，且可以估计出相应的稳定区域和渐近稳定区域．所得结果既是定性的又是定量的．

For quadratic delay difference systems,a preliminary quantitative stability theory is established.That is,under certain conditions one can not only confirm the uniform stability and uniform asymptotic stability of the zero solution,but also estimate the corresponding stability region and asymptotic stability region.Therefore,the obtained results are qualitative as well as quantitative.
