摘要
讨论了第三临界情形下的平面三次微分系统高次奇点附近的定性结构，给出由右端多项式系数的判断准则，并纠正和改进了［１］的某些结果．
The qualitative structure is discussed near the higher singular point of plane cubic differential system in the third critical case,a criteri on by the right-hand polynomial coefficients is given,and some results of the[1]are modified and improved.
