| Abstract: | This paper discusses the problem of thc stability of a nonlinear system of n first-order differential equations in the case that the characteristic equation of its first approximation has m-multiple zero roots,and arrives at criterions that can be respectively used to judge the trivial solution of the system stable or not. |

| Keywords: | critical case characteristic root characteristic vector stability |
