Development trend of azimuth aiming system of ballistic missiles abroad;

In order to solve the strong light interference during azimuth aiming process,an autocollimation angle measurement method based on moiré fringe was put forward combining the optoelectronic autocollimation principle with optical grating technique in dimensional metrology.

The location of aiming azimuth is an important part in the lunching procession of ground-to-ground missile,this paper based on the telemetry system and the error modal of IMU,acquired a new higher precision checking method and checking flow.

The Theory and Application of Benchmarking in Business Process Reengineering;

After analyzing the prospect of benchmarking in highway quality control,the paper mainly probes into enterprises benchmarking strategies and internal and external benchmarking methods in the selection phase of benchmarking and points out some key issues needing attention in the process.

This paper sums up the concept and origin of the theory of benchmarking, introduces five stages of the development of the theory of benchmarking, expounds the types of the benchmarking and the optimum flow of carrying out the benchmarking, and puts forward some problems needing attention in carrying out the benchmarking.
