Direct Factor Analysis With Discrete X-Ray Diffraction Patterns

In this paper,we put forward a method of direct factor analysis with discrete X-ray diffraction patterns, which was supported by the experimental measurement with the mixture containing 2,3,4,5 phases respectively. The detailed discussion was also given to its principles,errors and criterion.     

CALCULATION OF TNE END-EFFECT FACTOR OF SYNCHRONOUS MOTOR WITH CYLINDRICAL SOLID ROTOR

This paper presents the end-effect factor of Synchronous motor with cylindricalsolid rotor offered by analysing the 3-D electromagnetic field and using the Poynting vector.To ap-ply it in an actual calculation,the end-effect factor is proved correct and applicable.     

Concrete Evidence Reseach to the Aacepting Insurance Ability of China''s Non-life Insurance Companies

Owning to the ability of accepting insurance enough,it is the foundation for insurance companies to operate in a long-term and steady way,a method to develop sustainably,a reflection of an insurance company's comprehensive competition ability and also a premise for an insurance company to realize developing strategy.Accepting insurance ability is very important in the development and strategic planning for an insurance company.The quantitative analysis is used to analyze the ability of accepting insurance of our country's insurance companies,in another word,the factor(analysis),which belongs to the analysis of diverse statistic,is used.Using the method to give a concrete evidence analysis to the ability of accepting insurance of our country's non-life insurance companies,so that the insurance companies can understand very well to the advantages and disadvantages of the ability of accepting insurance to each other,and as well as supplying a strategic reference for the insurance companies themselves to make decisive planning.

The Algorithm of Searching out the Least and Most Loops by Making Use of Direction Factor

Based upon the conception of the least loop,the most loop and direction factor presented by the author firstly,the algorithm of searching out the least and most loops has been designed.By building the adjoining matrix, confirming the start-point of searching,vectorizing the searching sides,calculating the direction factor of adjoining sides,we can search out the next side of the least loop or the most loop rapidly.With a valid searching side being confirmed at every searching and the searching scope being reduced by forming degenerate graph,the time compexity of the algorithm is much less. In the research of the automatic calculating system of construction quantities, the problem of houses partition and out-wall partition had been solved succesfully by utilizing this searching algorithm.     

玉米穗腐病导致产量损失的品种和气候因素分析

1986～1990年的研究结果发现,在玉米穗腐病流行年份,抗病和感病玉米自交系的严量损失分别比常年高21％和35％。在气候因素中,日照时数对发病和产量损失影响较大。同一气候条件下感病系比抗病系产量损失大52％～82％。感病品种因穗腐病造成的玉水产量损失比不利的气候因素更为严重。     

三维复合材料复合裂纹特殊边界元法

利用两相复合材料位移基本解，将受复合载荷作用下复合材料三维裂纹问题，归为求解一组超奇异积分方程，并分析了对裂纹尖端应力奇性和方程组求解理论方法；进而以反映裂纹前沿应力奇性的密度函数基本解表示位移间断，根据Taylor积分及其特征展开特性，给出方程组数值求解方法；最后，以三维矩形裂纹为例，讨论了应力强度因子（SIFs）收敛性及其变化规律。
