给出了分块矩阵(ACB0)在满足ADBC =0,ABCAπ =0时的Drazin逆表达式,推广了[12]的结论；并且也给出了分块矩阵(ACB0)在BCAAD =0,AπBC =0时的Drazin逆表达式.
給齣瞭分塊矩陣(ACB0)在滿足ADBC =0,ABCAπ =0時的Drazin逆錶達式,推廣瞭[12]的結論；併且也給齣瞭分塊矩陣(ACB0)在BCAAD =0,AπBC =0時的Drazin逆錶達式.

The representation of the Drazin inverse for block matrix (ACB0) is given under conditions ADBC =0,ABCAπ =0,which generalizes the result of Chunyuan Deng in[12].Also,the representation of the Drazin inverse for block matrix (ACB0) is given under conditions BCAAD=0,AπBC=0.
