%X 本文研究了两个有界线性算子和的Drazin逆的问题.利用算子的预解式展开的方法，得到了（P+Q）D的具体表达式，并将其应用到四分块算子矩阵M=[CADB]的Drazin逆上，推广了文献[14，15]的结果.<br>In this paper, we investigate the Drazin inverse for the sum of two bounded linear operators. Using the resolvent expansion of the operator, the explicit representation of the Drazin inverse (P+Q)D is given. Then, we apply our results to the Drazin inverse of the operator matrix M=[CADB], which generalize the results in [14, 15]
