This paper gives the concept of-memory of S-rough sets and its-memory structure, puts forward-memory chaintheorem, -memory loop theorem and the knowledge complementary principle of F-memory chain.
F-memory characteristics of S-rough sets, F-memory theorem of S-rough sets and the knowledge loss principle of F-memory chain are presented.
利用这些概念,提出S粗集的f记忆特性,S -粗集的F -记忆定理,F -记忆链上知识丢失原理。

In this paper a theorem on translating DHMM into Homogeneous Markov Chain is presented. The theorem offers a method of using Homogeneous Markov Cain which is perfect in theory to study DHMM.
