过程驱动法实现协议栈软件有限状态机的分析

文章主要分析实现有限状态机(FSM)的方法:“过程驱动法”。有限状态机的抽象构建及实现是网络通信协议栈软件设计的基本方法。以GPRS协议移动台侧的子网相关汇聚协议层(SNDCP)为例,分析了用过程驱动法实现的程序复杂度、运行效率。文章最后提出用过程驱动法实现的主要数据结构。

Comparison between the theoretical models and experimental structures of some oc tacoordinated Ln(Ⅲ)-bis-dipyridyl-bis-dichloroacetato-diaquo complexes and their phenanthroline analogues

The title complexes were modeled using the semiempirical MOPAC and the newly developed SPARKLE paramerters of the lanthanides. The calculated bond dis tances and angles agreed well with those found from crystal structure measuremen ts. This technique allows us to screen a large number of molecules and get struc tural information within a very short time.
