Microstructure and oxidation behavior of carbon fiber reinforced SiC composite (Cf/SiC) with Mo–57Si–10B oxidation protection coating

Mo–57Si–10B (at.%) coating was prepared by the spark plasma sintering (SPS) technique on a 2D woven C_f/SiC composite, and the oxidation behavior of the bare and the coated C_f/SiC samples at 1300 ?°C were investigated. The coating was composed of a fine MoSi₂/MoB/SiO₂/Mo₂B₅ out layer and the inner SiO₂ interface layer. The mass gain percentage was approximately 0.25% after oxidation at 1300 ?°C for 100 ?h. The coated C_f/SiC substrate was effectively protected, owing to the rapid formation of the dense and protective borosilicate layer on the coating, the excellent microstructure stability of the coating and the inner SiO₂ interface layer.     

STUDY OF THE EQUILIBRIUM HCP CRYSTAL SHAPE BY THE ISING MODEL

The Ising model is used to investigate (0001), (10 10), (10 1l) interfaces, etc. , for the hcp lattice. The system studied here have the nearest-neighbor (NN) and next-nearest-neighbor(NNN)pair interactions. The interface energy, interface phase transition at zero temperature and roughening temperature are used to analyse the properties of these interfaces. As a special case of the hcp crystals, we give the equilibrium shape of the~4 He crystal at T=OK.     

录相机-微机图象处理系统接口电路设计

本文主要讨论微机图象处理的图象输入的硬件系统.与一般的图象输入系统不同之处是,本系统用价格便宜、性能可靠的录相机代替了磁带机作为记录与回放设备.下面以超声电视测井系统为背景来说明系统的构成.图1是系统框图.从录相机中回放的图象数据经放大整形、同步提取后经接口电路输入微机.由于放大整形及同步提取已在另文中介绍,所以本文仅讨论接口电路的设计.

A Design and Implementation of Multicrypt Solution for DVB Receiver

Conditional Access (CA) System is the essential basis of a Pay-TV System to charge the subscribers. This paper first introduces the standards and mechanisms for a Set-Top-Box(STB)to receive programs scrambled by different CA systems. Then, according to DVB multicrypt solution, a design in detail for such a DVB receiver, i.e. STB is presented. Decoder manufacturers provide STBs with the standard DVB common interface and CA system providers provide detachable CA modules to plug into the STBs through Common Interface. This solution allows broadcasters and customers to change CA system without replacing the STB. Such a design has been implemented in a decoder based on LSI SC2000, and is proved to be an open and secure solution for conditional access.
