本文利用元件寿命独立同分布时的相对老化次序，对相干系统进行随机比较。利用特征码刻画了相干系统的结构，得到了具有相同大小的比较系统在相对老化意义下可排序的几个充分条件.特别地，我们提出了一些场景，其中一个连贯的系统是，它的年龄越快。此外，我们还讨论了对偶系统的相对老化问题。给出了几个数值例子来说明理论结果。(c)2017 Wiley Periodicals，Inc.海军研究后勤64：345-354，2017
In this article, we carry out the stochastic comparison between coherent systems through the relative aging order when component lifetimes are independent and identically distributed. We make use of the signature to characterize the structure of coherent systems, and derive several sufficient conditions under which the compared systems with the common size can be ordered in the sense of relative aging. Specially, we present some scenarios wherein the better a coherent system is, the faster it ages. Moreover, we discuss the relative aging of dual systems as well. Several numerical examples are provided to illustrate the theoretical results. (c) 2017 Wiley Periodicals, Inc. Naval Research Logistics 64: 345-354, 2017
