1.So the research on the output performance of the air PDM is of great significance for the gas drilling during the horizontal well drilling.
因此，研究气体螺杆钻具在井下的输出性能对水平井气体钻井有着非常重要的意义。
2.Product data management (PDM) is a new technology of data management, and is important means of enterprise improving self competition.
产品数据管理是一项数据管理的新技术，是企业提高自身竞争力的重要手段。
3.The relation and the necessity of system integration on PDM and ERP are discussed. The content between them is analysed.
论述了PDM与ERP系统相互联系集成的必要性，分析了其集成的内容。
4.Stage 2. PDM was applied to the inbound movement of materials, components, and subassemblies, generally known as " materials management" .
第二阶段：PDM应用于物流、部件和半成品的往返流转活动，通常称之为“物料管理”。
5.Separate distribution departments were to coordinate the management of all processes within physical distribution management( PDM).
分离的经销部门得协调与货物配送管理（PDM）相关的所有过程的管理。
6.PDM system was used to support product structure configuration, suitable for reuse of structures and modules of parts and components.
PDM系统支持产品结构配置，适用于零部件结构和模块的重用；
7.Very few PDM systems in the past were recognized as simple and easy to use.
过去很少有PDM系统被认为简单易用的。
8.Finally, summarized and described the main implement process of the integration of PDM and EDA by a illustrative application instance.
总结了PDM与EDA集成的主要实现步骤；通过实例描述了PDM与EDA集成的整个过程。
9.Ultimately, electronics components would be managed as inpidual items, just like mechanical parts, in PLM and PDM systems.
但是将电子元件作为一个单一项来管理，上述的好处都不能获得。
10.PDM manages the relationships between data elements to provide control of product components during the creation and revision processes.
PDM管理数据元素之间的关系，为在整个创建和修订过程中对产品组件提供控制。
