质量特征
Examples
- Numerical simulating test on joint rock mass properties in three gorges project
三峡节理岩体力学性质的数值模拟试验 - Especially in aircraft ' s mass property management and calculation , it ' s inefficient and unacceptable to manage and calculate it by hand
尤其是在飞机质量特性的计算与数据管理中，传统的手工计算和管理已远不能达到设计技术要求，而且效率很低。 - The computation of mass properties adopts the discrete integration combined with the graphic construction of the srm structure , assuring the internal data coherence
对于质量特性的计算采用了离散积分的方法与发动机结构的图形构造结合起来，从而保证了数据的内在统一性并可以达到较高的计算精度。 - It is proved that the system ' s structure model is correct , the database model is proper and effective , and the result is accurate by building up and managing one aircraft ' s whole mass properties database
通过对已有飞机型号完整的质量特性数据库的建立和管理，表明系统的结构模型是正确的，数据库模型合理有效，质量特性计算准确、快速。 - This paper integrates rdbms ( relational database management system ) into aircraft ' s mass property management and analysis , solves some key problems of it , presents its data models and function models , designs its management frameworks and realizes them
本文将关系数据库管理技术与飞机质量特性分析计算相集成，有效地解决了质量特性分析与管理系统中的关键技术，提出了系统的功能模型和数据模型，设计了系统的管理框架并给予具体实现。
