For retarded time-delay systems, the stability can be determined by the rightmost characteristicroot.
为延迟时间延迟系统的稳定性可以通过最右边的特征根。

In this paper, we discuss the locally topological structures of nonlinear homogeneous systems with one zero characteristicroot, and give a criteria by the right-hand polynomial coefficients.
本文讨论了具有一个零特征根的非线性齐次系统的局部拓扑结构，并给出利用系统右端多项式系数的判断准则。

Chinese universities had a limited research role in the past, but the value of associating research with graduate education, characteristic of the Western model, has taken root.
