Studies on the fatty acids in the kernel oil of Prunus divaricata ldb .

樱桃李核仁油脂肪酸组成分析。

The synergistic mechanism of LDB may be related to the immuno-regulation of bystander effect of suicide gene therapy .

【结论】六味地黄丸可能通过自杀基因疗法旁杀伤效应的免疫机制或其他机制对肿瘤自杀基因疗法起到增效作用。

Ldb file is not deleted because it contains information about who was using the database at the time the database was marked as corrupted .

时然后，.ldb文件不删除因为它包含有关谁已使用数据库同时信息数据库已标记为损坏。

In multidatabase , access to global view will be decomposed to several sub-operations to several LDB , and perhaps also need data schema translation and query processing .

在多库系统中，对全局视图的存取操作要分解为针对多个LDB的子操作，可能还要对数据模式及查询语言进行转换。

In this article , local discriminant basis ( LDB ) algorithm based on wavelet packet transform ( WPT ) is utilized to implement feature extraction and emitters recognition .

本文基于小波包变换，采用局部判别基（LDB）方法进行辐射源信号特征提取与识别。

Meanwhile , the time requirement of DB2 and LDB is about the same as that of Document Frequency , Mutual Information or CHI Statistics , but obviously smaller than that of Information Gain .

同时，在时间上也具有相当的优势，DB2与LDB的时间代价与文档频次、互信息、CHI统计大体相当，但明显低于信息增益。

Because of the characteristics of multidatabase , for example , local database in multidatabase has autonomy and transaction in LDB is unaware to global transaction manager , and so on , transaction management in multidatabase is very difficult .

由于多库系统自身的固有特点，如底层数据库具有自治性、LDB的局部事务不为全局事务管理器所知等，使得多库系统中的事务管理一直是一个难于解决的问题。
