Since mechanical properties play important roles in the design and fabrication of the micro components, accumulation and perfection of the library has become one of the most important fundamental projects. 微机械力学性能对微机械的设计、加工等具有重要作用,积累和完善微机械力学性能库已经成为进行微机械研究的重要基础课题。
By summarizing the experiences of the campus mechanical factory of Shanxi Institute of industrial and vocational technology, this article takes the position that the pricing system perfection, management enhancement, and middling-segments reduction are effective resolutions for marking down procurement price 总结了山西工业职业技术学院机械厂的实践经验,认为完善价格机制、健全管理制度、减少中间环节是降低采购成本的有效措施
The mechanical properties of thermoplastic rubber depended on the content of PE and, to a lesser extent, on the crystallinity and perfection of crystallization. 热塑橡胶力学性质依赖于聚乙烯含量,同时,它与聚乙烯的结晶度及结晶完善程度有关。
