摘　　要：本文研究了一般状态跳过程的ｈ骨架的不变代数、尾代数之间的关系，并由此证明具有正则对的非常返跳过程存在成功耦合的充要条件是跳过程的所有有界调和函数都是常数。In this paper, the relation between invariant -algebra and tail -algebra ofjump processes in investigated, and from which, it is obtained that sufficient and necessaryconditions for existence of successful coupling for jump processes with regular q-pairs is thatall bounded harnionic functions for jump processes are constant.

关 键 词：尾σ代数 调和函数 成功耦合 跳过程 充要条件
