利用打靶法的數值結果說明了當系統平衡點不再發生穩定性切換時，源自這些臨界時滯處的解支的穩定性在整個解空間的穩定性具有不可判定性，這也說明由多尺度法所得高階近似判定的解支的穩定性事實上只表示解支在局部中心流形上的穩定性，而非在整個解空間中的穩定性。As a result, ( i ) let k ( x ) be the function assign to each point x of m the infinimum of the sectional curvatures of m at that ponit, if k ( x ) satisfies, then m is totally umbilical.
