The technology of modern auto maintenance demands more and more high technology,and the hightechnical characters in the modern auto maintenance are reflected from the employment of the electronic product in the automobile,the application of modern auto diagnosis equipment, the use of Internet in sharing of auto maintenance information to the role the maintenance management software plays in the auto maintenance company, etc.
OpsCon is used as the in-terface driver,iHistorian as the historical data platform and iFIX as the configuration software. In-foAgent is applied in assisant decision-making functions,such as real-time and historical data anay-sis,equipment status monitoring and malfunction diagnosis,equipment reliability and life manage-ment etc.
Interface transfer chip MC33290 and K-line configuration for vehicle diagnosis are introduced in this paper, and diagnosis program based on KWP2000 is developed, finally experiment is carried out through common rail system. One portable diagnosis equipment is chosen based on KWP2000 in order to meet the requirements of market.

In this paper, two methods of Abel inversion are applied to two different test profiles. The effects of random errors of input data, position uncertainty and number of points of input data on the inversion accuracy have been investigated. The two methods are compared in all aspects.
This paper introduces the survey of ultrasonic diagnostic instruments in our country and abroad and analyses small model two-dimensional uultrasonic diagnosis instruments in detail. The writer putsfo rward the opinions about development of this kind of the instruments.
In order to study the behaviour of plasma generated by laser beam in hohl-raum targets. we have performed a series of experiments in the Past three years, The experiments were conducted on a Nd: glass laser facility. The laser pulse parameters were as follows: wave length 1.06um. energy of laser pulse 150J-450J. pulse duration 0.7-1 ns. ratio of signal to noise 105 -106. energy of amplified stimulated spontaneous emission< 0.8mJ. beam angle drift<5", beam angle divergency<0. 1m rad and wavefront radius 300m.
