英文摘要：

The definitions of coefficient matrix and characteristic matrix for a central arrangement are given.We obtain the conclusion that the rank of a central arrangement equals to the rank of its coefficient matrix.Calculating characteris-tic matrix can be changed into calculating the rank of the sub-matrices of the coefficient matrix.The algorithm of char-acteristic polynomial of a central arrangement is provided.We study some properties of a modular element, and give a equivalent condition of judging a modular element, which simplifies the procedure of looking for a modular element. Based on this result, the algorithm of supersolvability of a central arrangement is offered.
