As to the levels of the public organization,the middle levels will reduce step by step and the public organization will be flatten,but the change of the number of the middle management is uncertain,it is possible to decrease、keep and increase the number of the middle management. As to the form of public organization,it will become networked、virtual and flexible. As to the distribution of the power of decision-making,the information technology improves the ability of decision-making of whole public organization and cause the redistribution of the decision-making power,recentralization and decentralization can coexist in the public organization,which depends on many factors.

The hardware and software is designed, including the formation and design of hardware system, visual instrument software architecture, program design for instrument driver, high speed real-time data collection. In the dynamic test program, the idea of"software is instrument"was applied to meet the diverse test demands. Last, it is proposed that the VXI test system be developed to more totalization and networked. The basic theory of system identification was introduced briefly at first. The principle of spectrum analysis system identification based on Wiener-Hopf equation was expatiated. and the questions in applying Peusdo Random signal as spectrum analysis methods stimulate signal was studied, The generation principle of the peusdo random signal is researched, the characteristic of peusdo random are analyzed from time domain and frequency domain, the inverse repeat peusdo random signal is brought forward to make up the shortage of ordinary peusdo random signal. And a new chaos genetic algorithmis presented to solve the unprecise problem of the traditional method. In the servo valve dynamic characteristic test system, the spectrum analysis methods was applied successfully, the servo valve dynamic characteristic could be acquired rapidly and exactly, the test results were analyzed and the ameliorate methods were brought forward at last.
