JOINING MECHANISMS OF β''''-Al2O3 CERAMIC AND PYREX GLASS TO Al MATRIX COMPOSITE

The bonding of β'-Al2O3 and pyrex glass to Al matrix composites by anodic bonding process is achieved. The microstructure of the bonded interface and the joining mechanisms are analyzed with scanning electron microscope (SEM), energy dispersive X-ray fluorescence spectrometer (EDX). It is observed that the bonding region across the interface consists of the metal layer, oxide transitional layer and the ceramic layer, with the transitional layer composed of surface region and sub-surface region. The bonding process can mainly be categorized into anodic bonding process and solid state diffusing process. The pile-up of the ions and its drift in the interface area are the main reasons for anode oxidation and joining of the interface. The temperature, voltage and the drift ions in the ceramic or glass during the bonding process are the essential conditions to solid state diffusing and oxide bonding at the interface. The voltages, temperature, pressure as well as the surface state are the main factors that influence the anodic bonding.     

电视导引头模型参考控制器设计

借鉴模型参考控制器的设计思想,采用经过线性二次型输出反馈控制后的系统作为参考模型,以它的输出作为期望输出,让实际输出跟随这个期望输出;二者的误差信号反馈到原系统的输入端,设计出一种模型参考控制器.经该控制器优化后,电视导引头系统的快速性可得到较大提高.参考模型可由RC网络或计算机软件来实现.     

氨氮监测中样品蒸馏预处理对结果的影响分析

氨氮监测采用预蒸馏处理后，比色测定结果明显偏低。在样品预蒸馏处理过程中，硼酸作为吸收液，使显色时溶液pH值偏低，导致显色不充分是其主要影响因素。通过采取增加显色剂加入量的方法，解决了显色pH值偏低的问题，得到满意的测定结果。     

The new structure of fibre glass reinforced plastics bolt

The develop actuality and direction of FRP (fibre glass reinforced plastics) bolt in the world are analyzed. The new type structure of FRP bolt was designed. Trial data indicate that, all kinds of capability target of this FRP bolt all achieve and exceed the country stand-ard, substitute present metal bolt, wood bolt and bamboo bolt and other side bolt, it can gain magnitude technology and economy benefit. FRP bolt mechanization product line produce ef-ficiency is high, its throughput a day are 750 base, this can meet demand of hit-small mining company.
