Abstract:The differential equation of the measuring system is described in this paper. Using the input and output data determines the dispersed transmitted function of its system. Because it can make up the defect that the accelerometer can't give the dynamic characteristics during the calibration of accelerometer sensitivity. The accelerometer's output signal can be returned to the "real" in-situ shock acceleration-time course by the dispersed transmitted function within a certain range of dynamic characteristics.

Abstract:According to the properties of TDICCD,the effect of optical system and pixel dimension on resolution is analyzed and the effect of CCD noise, speed-altitude ratio and exposure control on image quality is discussed. After adopting the correlated double sampling technique, automatic speed-altitude ratio and automatic and exposure control,the image quality of TDICCD camera has been improved.

Abstract:Starting from the point of view of information security, this paper researches the security mode in the Blutooth information transmission. An analyses of the Key Management of Bluetooth Technique was also given and the author's viewpoints are put forward as well.

Abstract:The design for automatic metrology and measurement of the tape recorders is described in this paper. It mainly introduces the designs of the program control multichannel signal selector (PCMSS) and GPIB interface of PCMSS. The design of the software of automatic test is presented briefly.

Abstract:In this paper, the problem of electro-magnetic compatibility in weight-measuring instrument is described. According to the practical requirment, some measures are adopted and the performance of electro-magnetic compatibility is improved.

Abstract:Four methods to determine the cam initial revolving angle during its calibration are introduced. And its usage is discussed as well.

Abstract:The VXI bus measuring system for the test of the engine stability is such a test system developed for the distortion test of the entering air flow field of turbofan/ turbine aircraft engine and the test device for studying the pneumatic stability. The system has achieved the internal advanced level. This paper introduces the function, constitution,operating principle and software design of the system.

Abstract:The structure, features and principle of the ZSZ series synchro/digit converter are introduced in this paper,and the practical interface circuit is also discussed in detail.

Abstract:The uncertainties of measurement of the single groove specimen calibrating device are analyzed in this paper. The uncertainty of the sigle groove specimen calibrated by this instrument is analyzed as well.

Abstract:This paper sketches out the component of the environment parameter data acquiring system. It mainly introduces the methods to acquire the temperatures of the air and ring gauge. Using ActiveX control component to realize RS232 serial communication,the methods of acquiring the atmosphere pressure and the air humidity are presented.
