摘要
证明了 DMRL偏序关系在平移和尺度变换下的不变性 ,并获得了一个充分必要条件 .同时考虑了 DMRL序与 IFR及
It is proved that the DMRL ordering is maintained under the translation and scale transforms. A sufficient and necessary condition for DMRL ordering is presented. The relationships between the DMRL ordering and the IFR ordering or IFRA ordering are investigated as well.
