研究了具有独立分量的线性（循环）连续k-out-of-n：F系统的随机比较问题。给出了一个循环连续k-out-of-n：F系统的寿命在n中随机递减的充分条件.此外，还建立了具有独立同分布分量的线性（循环）连续k-out-of-n：F系统寿命的似然比序，并给出了一些反例说明这些序一般不成立.
Stochastic comparisons of linear (circular) consecutive k-out-of-n:F systems with independent components are studied. A sufficient condition is given under which the lifetime of a circular consecutive k-out-of-n:F system with independent and nonidentically distributed components is stochastically decreasing in n for fixed k. Furthermore, the likelihood ratio orderings of the lifetimes of linear (circular) consecutive k-out-of-n:F systems with independent and identically distributed components are also established, and some counterexamples are given to show that these orderings are not true in general.
