Manufacturing Communication： DCOM-MMS-based Approach for Flexible Manufacturing System

A design approach of manufacturing communication is presented for flexible manufacturing system in this paper. The primary objective aims at making the flexible manufacturing ,control system provided with interoperability and reconfigurability. Based on describing manufacturing message specification （MMS） and distributed component object model （DCOM）, a client/server manufacturing communication model is built with MMS standard and DCOM middleware, and the communication interfaces between MMS client and MMS server are designed with Microsoft interface definition language （MIDL） and abstract syntax notation one （ASN. 1） of MMS services. As a result, DCOM and MMS integration leads to such client/ server communication capabilities independent of different operating systems and manufacturing devices in flexible manufacturing automation environment. Finally, to verify the new design approach, a prototype system of robot control system has been implemented in MS 2000 Server/Professional Operating System and VC ＋ ＋ 6.0 Developer Environments.     

GaN/Al_xGa_(1-x)N量子点中类氢杂质位置对激子态的影响

利用有效质量方法和变分原理,考虑内建电场效应和量子点(QD)的三维约束效应,研究类氢杂质对GaN/AlxGa1-xN量子点中激子态的影响.结果表明:量子点中心的类氢杂质使激子的结合能升高,基态能降低,QD系统的稳定性增强,发光波长红移.杂质位于量子点上界面时,激子的基态能最小,结合能最大,系统最稳定.随着杂质从量子点的上界面沿着Z轴移至下界面,激子基态能增大,结合能减小,带间发光蓝移.

Rare earth effect of yttrium on formation and property of Cr_2O_3 oxide film formed on Co-Cr binary alloy

The isothermal oxidizing kinetics of Co-40Cr alloy and its yttrium ion-implanted samples were studied at 1000 ℃ in air by thermal-gravity analysis (TGA). Scanning electronic microscopy (SEM) was used to examine the Cr2O3 oxide film's morphology after oxidation. Secondary ion mass spectrum (SIMS) method was used to examine the binding energy change of chromium caused by Y-doping and its influence on formation of Cr2O3 film. Acoustic emission (AE) method was used in situ to monitor the cracking and spalling of oxide films formed on both samples during oxidizing and subsequent air-cooling stages. Theoretical model simulating the film fracture process was proposed to analyze the acoustic emission spectrum both on time domain and on AE-event number domain. It is found that yttrium ion-implantation can remarkably reduce the isothermal oxidizing rate of Co-40Cr and improve the anti-cracking and anti-spalling properties of Cr2O3 oxide film. Reasons for the improvement are mainly that the implanted yttrium can reduce the grain size of Cr2O3 oxide, increase the high temperature plasticity of oxide film, and remarkably reduce the number and size of Cr2O3/Co-40Cr interfacial defects.
