Abstract:The turbiscan analyzer based on the multiple lightscaterring , which can be used to detect the sta－bility of food emulsification system directly , rapidly, and accurately.This paper introduced the working principle of turbiscan analyzer firstly.Then reviewed majorly its application and research process in evaluation of destabili－zation adopting four methods , which included the backscattering (ΔBS), transmission (ΔT), turbiscan stability index ( TSI), milk analysis index, and particle size.The aim is to provide the reference for the study on the sta－bility of turbiscan analyzer in the food emulsification system.

Abstract:By an analysis of the operation of heat sink, a new method is proposed for the calculation of thermal resistance for air - cooling heat sink of power semiconductor parts. For the calculation, there are 2 steps ： internal heat transmission and the surface heat diffusion. The basic formulae for each step are provided, and the results are verified by using the heat sink thermal resistance curve provided by the manufacturer. The calculation result shows that this method is easy and accurate.

Abstract:As one of the most important devices in academic area,classification algorithm is analyzed and compared with current ones well recognized,and its property is provided for the present application and future improvement.

Abstract:This paper analyzed the main content and characteristics of claims service , pointed out that the claims service status of insurance company is needed to be improved and indicated the importance of service quality evaluation index system .The fuzzy comprehensive quality evaluation model was used .The service quality evaluation index system with recursion order hierarchy structure of insurance company was established .Compre-hensive evaluation method of secondary indicators and first -level index through analytical hierarchy process .Fi-nally , according to the index evaluation method and the reality of insurance claims , a series of solutions were put forward .

Abstract:Multi－motor cooperative control system was applied to printing machine,paper machine,traction of high speed train and so on.In this paper,first of all, the development status and research significance of multi－motor cooperative control are introduced. What′s more,the structure and characteristics of multi－motor coop-erative control strategies such as parallel control, master －slave control, cross －coupling control and virtual spindle control are introduced respectively. They are simulated in MATLAB/SIMULINK, and their advantages and disadvantages are compared. According to the response characteristics of different control strategies, the most suitable control methods for production system are summarized.
