The holistic design of the system and resolved the designs of software and hardware based on VXI bus are put forward according to the demand of test system. 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.

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.
在流域输沙量动态模型的建立中,由于研究时段长、研究流域尺度大,对输沙量各影响因子进行全流域逐年动态监测十分困难,考虑输沙量的年际变化主要受降雨-径流水文条件和水土保持措施等土地管理活动的影响,首次提出与地表径流模数和治理时间相关的综合影响因子,并通过因次分析法和二元非线型回归法确定了具体的表达式。
