刻画了图的弱自同态幺半，群的结构，通过刻画图的弱自同态幺半群的格林关系，给出了弱自同态是正则元的充分必要条件．
刻畫瞭圖的弱自同態幺半，群的結構，通過刻畫圖的弱自同態幺半群的格林關繫，給齣瞭弱自同態是正則元的充分必要條件．

In this paper, we characterize the structure of the weakly endomorphism monoids of graphs. Furthermore, we present the necessary andlsufficient conditions for,a weakly endomorphism to he a regu- lar element.
