The preparation,characterization and chiral separation of kanamycin-CSP in normal phase were discussed.
通过对卡那霉素CSP的制备、表征及在正相条件下对异博定、黄皮酰胺、萘乙醇等三种物质的手性拆分研究,探讨其手性拆分机理。
Some uninteresting rules can be avoided by using the lift to judge the positive correlation between the antecedent and the consequent of an association rule,while generating association rules from frequent itemsets.
在由频繁项集产生关联规则时,利用提升度判断规则前、后件之间的正相关性可以避免产生一些无意义的关联。
The result shows that a high positive correlation between tropical easterly current and.
结果表明:在阿拉伯海及孟加拉湾热带气旋生成数与100hPa东风气流强度之间存在极好的正相关关系,即东风气流加强热带气旋数目增多,反之减少。
This paper explains the positive correlation of employment and social stability:the guarantee function,the encouragement function,the security function,and the incorporation function the cooperation function,facilitate to realize the social stability.
就业与社会稳定的正相关:就业的保障功能的发挥、激励功能的发挥、融入功能的发挥、协作功能的发挥,都有助于实现社会稳定。
)stands for a point in R~N,then the following positive correlative property is ture:∫_(R~N)fgdP≥∫_(R~N)fdP∫_(R~N)gdP.
设N是自然数全体,{μn}n∞=1为R1上的任一概率测度序列,记P=∏n∈N上f(x1,x2,…,xn,…)与g(x1,x2,…,xn,…)关于每个分量是上升的,其中(x1,x2,…,xn,…)表示RN中的点,则有如下的正相关性成立:∫RNfgdP≥RNf∫dPRNg∫dP。
