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.

WIt wasn't till several years ago that the idea of returning to nature overwhelmed society. As the world progressed, the demand for better interior design increases. It is no more European or American splendour nor is it traditional designs that take precedence in today's interior designs. Instead, there is a heightened demand to fuse these unique elements and to recreate spaces that emphasise togetherness. The interaction of space, hence, becomes an important aspect in conceptualisation. Showflats are artificially conceived spaces built to evoke inspiration for interior design. At the same time, it takes a confidential peep at others'"perfect" private room by looking at the showflat as the reference of their lives.

直到几年前，回归自然的概念开始充斥着整个社会；随着世界的进步，人们对室内设计的要求也越来越高；如今室内设计不再追求欧美的华丽风或是传统风格，相反的，而是要将这两种单一的元素融合在一起来形成统一的空间；因此，空间的相互作用将变成设计概念上重要方面；样板房是一种能唤起人们对屋内设计灵感的一个人为设计的空间，它的魅力在于能够通过样板房窥视他人的生活的完美空间来作为自己室内设计的参考。

The virtual construction training flow is introduced. Before construction, technicians can rehearse the whole construction process again and again in virtual environment, until they master every detail of the whole construction process. Therefore, that ensures the complicated construction would go with a swing in the construction site.

本文对建筑结构虚拟动态设计方法进行了探索，该方法强调设计人员利用现有的设计和分析软件，沉浸在三维可视化虚拟环境中，对模型进行结构动态优化设计，充分发挥设计人员的想象力和创造力，使设计人员的经验和科学计算完美地结合在一起。

The process features and shape features of the electronic part are classified and defined, and then the feature model library is built, which enables rapid input of the part information. The rules and methods of stamping process design are summarized to build the stamping process library, so that the stamping process can be designed rapidly and intelligently. Furtherly, the process design rules and methods in process station layout of multi-station progressive die as well as the methods of decompounding and compounding process and the expression method of the process station layout are concluded and summarized, and then the rule library and case library of process station layout are built. Designing the process station layout rapidly is carried out based on rules and cases. At last the rapid design function of process station layout is validated through simulating the rapid designing layout system of multi-station progressive die on Pro/E 3D platform.
