本文系统地介绍了利用~(13)C-NMR数据库系统统计法建立带有键属性亚结构与~(13)C-NMR化学位移相关表(结构解析专家系统的约束知识库的一个组成部分)的过程。在亚结构的选择上作了深入的探讨。在亚结构检索上提出了加权码值计算方法。
In this paper, we systematically introduced the establishment of a 13C-NMR chemical shift correlation table (a component of the constraint knowledge base of structural analysis expert system) using the 13C-NMR database system statistical method. the process of. In the sub-structure of the choice made in-depth discussion. In the substructure search, a weighted value calculation method is proposed.
