Abstract:Based on the perturbation theory, it was proved that the ratio of changes of frequencies is the function of structural damage location. Taking a uniform cross-sectioned simply supported beam for example, the ratio of changes of frequencies between the damaged and intact beam was used to locate and qualify beam damage. For different extents of damage, the changes of frequencies and ratio of changes of frequencies were studied and the effects resulted from the omission of second order items were discussed. Finally, the deficiency of this method was pointed out.

Abstract:Based on the definitions of air conditioning period, dehumidifying period and heating period, this paper puts forward the exchanging conditions and psychrometric process of ventilation system in residences. Because of the remarkable humid climate in hot summer and cold winter regions, the ventilation dehumidification becomes a more important part of the air treatment system. In order to improve the indoor thermal environment quality, new strategies must be founded to control both temperature and humidity of ventilation system.

Abstract:In this paper the low-temperature hydraulic floor heating system of a residence in Chongqing was tested. The influence of this system and the heat pump air conditioning system on indoor thermal comfort and operation cost was analyzed and compared. The effect of heat dissipation by radiation and convention of the floor was analyzed. It shows the feasibility and advantage of floor heating system in Yangtse River Region.

Abstract:Based on analysis of the function of dummy arrow in network diagram, this paper provides some methods to determine and delete additional arrows. It will be helpful to personnel in engineering network planning for determining and deleting the additional dummy arrows quickly and correctly.

Abstract:In China, the spare commercial housing area is continuously increasing at present. But most people don't satisfy their present living conditions, they want to enlarge the housing areas and to ameliorate their living environment. So there has a contradiction between the people's living level and their requirement. In this paper the whole process marketing strategy system of real estate was put forward to solve the problem. That is, a series of marketing strategies such as pricing strategy, promotion strategy etc were suggested.

Abstract:The new listed real estate companies will greatly influence the real estate stocks in Shenzhen and Shanghai Stock Exchanges. Based on this special background, this paper established an operable model by comprehensively applying the Grey Theory, DEA Appraisement and its sequence arrangement method to compare various values of real estate stocks.

Abstract:According to enterprise's running environment and economic level, great housing industry group should be formed with concentrated intelligence, skill and fund as well as specialization and integration. Different establishment models can be adopted by housing industry group to realize housing industry modernization and promote the development of national economy.

Abstract:制备高性能混凝土所用的细集料应首选中、粗砂，而特细砂乃至比特细砂更细的粉砂不利于配制高性能混凝土，本文利用粉砂，在大量试验基础上，成功配制出塌落度≥200mm,扩展度≥600mm,28d抗压强度≥100MP的粉砂高性能混凝土。

Abstract:This paper introduces some common harmonic damage of power usage in civil building and analyzes some reasons for it. Then, some practical and simple restraining methods are suggested and some calculating methods are given as reference for electric engineering technicians.

Abstract:In this paper the common submersible pump and the foul water submersible pump were compared with the submersible sand pump. Then, the principle and structure features of the submersible sand pump were introduced. The hydraulic pattern of submersible sand pump was designed according to two kinds of fluid theory. There is an air room at submersible sand pump added. The motor axle of submersible sand pump was extended from the air room. Inside the motor there is a small reservoir and the drop of water can be collected. The working condition of submersible sand pump was improved. The submersible sand pump can work longer time.
