高阶近似 meaning in English

high-order approximation

Through such a study , it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt , the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space , that is , their stability depends on cases . this phenomenon also implies that the stability of the periodic solutions on the bifurcation diagrams indicates only the stability on the local center manifo ld . some distinguished features of delay dyn
利用打靶法的数值结果说明了当系统平衡点不再发生稳定性切换时，源自这些临界时滞处的解支的稳定性在整个解空间的稳定性具有不可判定性，这也说明由多尺度法所得高阶近似判定的解支的稳定性事实上只表示解支在局部中心流形上的稳定性，而非在整个解空间中的稳定性。
