Abstract:In this paper,some commonly used sine wave modelling measuring methods are reviewed,they are sine ware curve\|fitting method,histogram statistical analysis method,FFT method and beat frequency method.The typical applications and their characteristics of these mehtods are described in detail.

Abstract:The method of aerial camera auto\|focussing by area\|array CCD intersection measurement in conbination with the edge characteristics of the image wavelet transform is suggested.The design scheme of the hardware and software of the test system is proposed.

Abstract:The paper mainly describes the general procedure of object\|oriented modelling system simulation from object\|oriented modelling and system simulation modelling;With this procedure, the modelling simulation environment for flight control system is set up.

Abstract:An accurate power amplifier composed of thick film integrated power amplifier and fixed amplitude circuit is presented.Its stability,frequency response and waveform distortion are all reached a very high level.

Abstract:Fiber\|optic cable sensor is a kind of new sensor technology developed in recent years.The structural principles and the applications in different fields of two different types of new fiber\|optic cable sensor are presented in this paper.The vast application prospect of the fiber\|optic cable sensor in measuring field is introduced also.

Abstract:With a designed special verification tool and making the two thermocouple bunches installed from two directions meet the requirement of the verification regulation,the efficiency of verifying TC is greatly raised under the situation without increasing any new equipment.

Abstract:Through the analysis of the effect on the linearity of carriage moving of the universal measuring toolmaker microscope,the repair method has been proposed.And the main reasons effecting linear deviation and angle deviations are expounded respectively.

Abstract:This paper introduces several optimization methods for C51 program of series 51 single\|chip computer.The program and data storage space can be reduced efficiently through these methods,so that the limited hardware resource within the single\|chip computer can be fully exploited.These methods can be adapted to the other C language programs.

Abstract:Around the variety and the completeness of the developing tools and operating system of the 51 series single\|chip computer product,the vital phenomenon of 51 series single\|chip computer is presented,even though the situation of all flowers bloom together has been presented already.The new number of the 51 series single\|chip computer,ADuC812,is introduced briefly in this paper.

Abstract:The design method of realizing automation of verification process with using single\|chip computer for the control of the lever force standard machine is introduced.The hardware construction and software programming are described emphatically.

Abstract:The paper introduces metrological certification and assessment related issues improved by measurement & testing centre in unclear industry and great changes brought by the issues.
