ocl

Carbon support with a smaller diameter and thickness is beneficial to the OCL performance.

较细的碳载体直径会适当改善催化层性能.

Object Constraint Language ( OCL) is the sub-standard of UML, which can be used not only in constraint and query on models, but also in defining transformation rules and modeling language.

首先对模型转换语言的特性和现有的主要模型转换语言进行了简要的说明和分析，然后对对象约束语言（OCL）作为模型转换语言进行理论相关分析。

基于OCL技术的Oracle数据库数据快速存取研究

As previously mentioned, the UML API does not allow evaluating OCL expressions on a model level.

如上所述，UML API并不支持在模型层次上评价OCL表达式。

If with the OCL way work, uses the single power source power supply.

若用OCL方式 工作, 则采用单电源供电.

Constraints are specified using oAW's Check language ( essentially a streamlined OCL)

约束可以使用oAW的Check语言（本质上是一个简化了的OCL）来指定。
