Abstract:Clibrating turbine flow meter is traditionally static meter\|factor.This thesis introduces the theory and practice method of calibrating the dynamic character of turbine flow meter.

Abstract:This paper discusses some problems in the design of the gas flow probe on the satellite propulsion system.This probe suits the measurement of micro gas flow,which conforms with the theory of the differential\|pressure orifice flow meter,and it is designed light and handy and used conveniently.This probe can export current be transferred distorionlessly with long distance and this brings great convenience for measurement on the spot.

Abstract:A method of using the reflecting diffractive grating to measure the instantaneous strain is described in this paper.Using one dimension bar which is thin and long,named Hopkinson bar,the strain value and the sensitivity coefficient K of the strain have been got after measuring the absolute velocity of the end of the bar.The theory calculation and the experimental result are analysed.The conclusion on this method is given and the farther research orientation is pointed out.

Abstract:The verification method of ITS9000 series VLSI test system based on ITS9000MX VLSI test system is introduced in the paper,and its basic thought,principles and the key technologies are described

Abstract:This paper introduce the basic theory of the hot\|wire/film anemometer and the method to determine the flow velocity of calibration nozzle system.This calibration nozzle system is designed for the calibration of hot\|wire/film anemometer.A method to determine the uncertainty of this system is fully analyzed using uncertainty thoery in this paper.

Abstract:In this paper,the formula in the evaluation of standard uncertainty for the parameter in smooth change is derived from characteristics of random error.

Abstract:The article introduce a method to solve the problem of temperature conpensation for micro dynamic piezorsistive pressure sensor,including a set of computational formula.The main characters of this method are convise,simple and convenient

Abstract:The device introduced in the paper presents the solution on signal acquisition with lithium chloride humidity sensor by applying operational amplified digital circuit.For accurate measurement,correction necessary against temperature is alse made and introduced in the paper.The designing and methods can also be widely adopted on any linearised sensor.

Abstract:The application of index technology of precise terminal gear,the product developed by itself and the direction of technical development are introduced in this paper.

Abstract:The intelligent electric\|magnetic flowmeter,integrating the sensor,converter and integrator onto it,and displaying on the spot,is introduced in the paper.The advanced chip microprocessor and the chip are adopted in it and the on\|line signal acquisitions and data processings are realized.And the fault\|tolerant technique of software is also adopted,so that the reliability of meter and the accuracy of measurement are increased greatly.

Abstract:A data management system for the calibration of electronic total station is presented in this paper.The system is based on FOXPRO FOR WINDOWS and a module structure is adopted.It has functions such as data input and data correction,automatic conversion of data type,parameter calculation,query and display of data,so both the data management and data processing are realized.
