摘　　要：给出实数域上次正定阵的若干判别准则、行列式不等式；指出文［１］的错误，给出几个重要反例。In this paper, we prove some properties on the matapositive definte matrices, and give anecessary and sufficient condition for that a matrix is metapossitive definite. Some determinant megualitiesfor the matapositive definite matrices are proved, some errons in [1] are pointed out, some examples are gave.
