摘要
软件企业随着业务的积累与规模的增加,其所积累的领域知识与开发过程材料也变得愈加丰富。这些知识对于企业的发展有重要的意义,但由于内容庞大,难以转化为对当前工作的支持。为了解决这一问题,提出使用中文分词相关技术对企业知识自动提取关键词、摘要、技术要点等以此达到快速检索企业已有知识的目的,最大程度提高软件的可重用性,为软件整个开发过程控制与信息化管理提供支持。
This paper studied the impact of trace boron on the microstructure and performance of C100 drive gear and the influence of both surface quenching and plasma nitriding on the performance were investigated. The results showed that the addition of trace boron can improve the hardenability of gear materials and the grain refinement of hardening layer. The quenching layer of the sample of boron containing about 0. 003% was the thickest and the grains of this sample were finer. The depth of the hardened layer was close to that of the 16 -hour -nitrided layer, but the hardness of high frequency quenching was higher.
