Micro-gas turbine engine(MTE) rotor is an important indicator of its property, therefore, the manufacturing technology of the microminiature rotor has become a hot area of research at home and abroad. At present, the main manufacturing technologies of the MTE rotor are directed forming fabrication technologies. However, these technologies have a series of problems, such as complex processing technology high manufacturing cost, and low processing efficiency, and so on. This paper takes advantage of micro electric discharge machining(micro-EDM) in the field of microminiature molds manufacturing, organizes many processing technologies of micro-EDM reasonably to improve processing accuracy, presents an integrated micro-EDM technology and its process flow to fabricate MTE rotor die, and conducts a series of experiments to verify efficiency of this integrated micro-EDM. The experiments results show that the MTE rotor die has sharp outline and ensure the good consistency of MTE rotor blades. Meanwhile, the MTE rotor die is applied to micro extrusion equipment, and technologies of micro-EDM and micro forming machining are combined based on the idea of the molds manufacturing, so the MTE rotor with higher aspect ratio and better consistency of blades can be manufactured efficiently. This research presents an integrated micro-EDM technology and its process flow, which promotes the practical process of MTE effectively.- 中国机械工程学报文章来源: 万方数据

Structure design and fabricating methods of three-dimensional(3D)artificial spherical compound eyes have been researched by many scholars.Micro-nano optical manufacturing is mostly used to process 3D artificial compound eyes.However,spherical optical compound eyes are less at optical performance than the eyes of insects,and it is difficult to further improve the imaging quality of compound eyes by means of micro-nano optical manufacturing.In this research,nonhomogeneous aspheric compound eyes(ACEs)are designed and fabricated.The nonhomogeneous aspheric structure is applied to calibrate the spherical aberration.Micro milling with advantages in processing three-dimensional micro structures is adopted to manufacture ACEs.In order to obtain ACEs with high imaging quality,the tool paths are optimized by analyzing the influence factors consisting of interpolation allowable error,scallop height and tool path pattern.In the experiments,two kinds of ACEs are manufactured by micro-milling with different too path patterns and cutting parameter on the miniature precision five-axis milling machine tool.The experimental results indicate that the ACEs of high surface quality can be achieved by circularly milling small micro-lens individually with changeable cutting depth.A prototype of the aspheric compound eye(ACE)with surface roughness(Ra)below 0.12?m is obtained with good imaging performance.This research ameliorates the imaging quality of 3D artificial compound eyes,and the proposed method of micro-milling can improve surface processing quality of compound eyes.- 中国机械工程学报文章来源: 万方数据

基于NET平台的中医药防治传染病知识系统构建研究与思考
以现行国家法定传染病分类标准,建立基于NET平台的中医药防治传染病知识系统多媒体网站.建立基于NET平台的中医药防治传染病知识系统,可在一定程度上为公众提供已有的传染病相关知识,减少不必要的恐慌;还可提供相关疾病的中医药常用预防思路与方法,满足这方面的需求.建议在此基础上,以各地专家的临床经验为依据,建立中医药防治传染病的名医工作室,逐步体现因人、因时、因地的个体化治疗特色.但要真正实现对中医辨治信息进行有效的数据挖掘,中医外感热病证素的标准化、规范化是急需解决的问题.周晓平,马勇,陈金辉 - 长春中医药大学学报文章来源: 万方数据 -

聚醚砜微图案膜的模板法制备及性能表征
以聚醚砜(PES)为基质膜材料,利用微图案硅片为模板,通过非溶剂致相分离法(NIPS)制备PES微图案膜,研究制膜条件对膜表面微图案及膜结构、性能的影响,考察图案化前后PES膜的水通量、接触角、孔隙率、拉伸强度性能差异.结果表明,以模板法制得的PES 膜表面呈现规整的微图案,且膜表面微图案的规整性随铸膜液中PES浓度的增加而提高.接触角、孔隙率和水通量测试表明,相对于PES原膜,制得的微图案膜具有较高的接触角和较高的孔隙率及水通量;机械性能测试表明,图案化前后膜的拉伸强度变化不大.万伟娜,张玉忠,林立刚,丁晓莉,李泓 - 膜科学与技术文章来源: 万方数据 -
