  3. The discussing process follows the steps below : first, suppose the system ( 1 ) has only one finite singular point ( 0, 0 ). then we can assume b50 = 0, which special direction is determined by equation g ( 0 ) - 0, introduce poincare transformation to discuss infinite singular points, according to the coefficient conditions, list all possible infinite singular points and special directions, judging their type, drawing out all kinds of phase portraits

    本文主要內容為:一、假設系統( 1 )只有唯一的有限遠奇點( 0 , 0 ) ,則不妨設b _ ( 50 ) = 0 ,其特殊方向由示性方程g ( ) = 0給出,引進poincare變換研究無窮遠奇點,再根據各定理中的系數條件,列出系統所有可能的無窮遠奇點和特殊方向,並判斷其類型,由此畫出系統的各種可能的全局相圖。
