relational matrix

In the database subsystem, the retrieved documents are represented by the fuzzy relational matrix of index-terms-documents, for each index term is weighted by a numerical weight according to its presence frequency in the document.

在数据库子系统，用索引词&文档模糊矩阵表示待检索的文档，对每个索引词，根据其在文档中的出现频率大小，引入了数值权重；

The combustion of emulsion explosive matrix is nearly relational with the temperature of the environment, the delayed-action time will extend when the non-adiabatic semenov parameter is around the critical value.

其燃烧与环境温度有着密切的关系，当非绝热semenov数处于亚临界和临界值时，爆炸延滞期延长。
