英文摘要：

A regular （0, 1）-matrix is a （0, 1）-matrix which has constant line sums. In order to better understand the combinatorial properties of regular（0,1）-matrices, the row coincidence number problem of regular（0,1）- matrices is studied, upper and lower bounds for the row coincidence number of regular（0,1）-matrices are given, which shows that the upper bound is precise in some cases. Moreover, the determinants and singular values of the regular classes of （0, 1）-matrices are determined whose row coincidence numbers are 1.
