| 摘 要： | 主要对2个随机变量X和Y在常用随机序下的情况进行了研究,验证了在一定的条件下,普通随机序可推出失效率序、反失效率序、平均剩余寿命序,以及增凸序可推出平均剩余寿命序,是对随机序之间相互关系的推广及完善.

| Abstract: | The relations between common stochastic orders are studied.It is proved that under some certain conditions,the hazard rate order,reversed hazard order and mean residual life order can be derived from common stochastic orders and the increasing convex order can result in the mean residual life order,thus promoting and perfecting the relations between stochastic orders. |

| Keywords: | common stochastic order hazard rate order reversed hazard order mean residual life order |
