结果表明，平原区浅层土壤内Cd、Pb、Zn元素的分布明显不同于物源区及平原区深层土壤，在元素之间的典型相关关系及元素富集的分布特征上，均表现出明显的人为源特征。

Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.

利用SAS的SQL和MACRO等语句编写了大量的程序，以拟合优度检验结果为标准，不断地变换八种分布的参数变化范围，通过宏程序的不断循环，逐步缩小参数的范围，最后达到预先设定的标准，从而可以发现八种分布中哪几种分布能比较好地拟合给定的实际频数资料，我们再根据拟合优度检验的结果判断出哪种分布拟合实际频数资料最好，最终获得该频数资料的最佳的理论分布函数形式。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

In this paper, photoelastic coating method and strain-gauging method were used conjointly to study the stress distribution of the column of cross wedge rolling machine. The result of study deepened the understanding of this complicated problem and there is certain reference value on improving the stress distribution of the column.

本文利用光弹性贴片法，辅以电阻应变片法，对楔横轧机机架模型的应力分布规律进行了研究，研究结果深化了对这一复杂问题的认识，得到了一些有价值的结论，对于采用合理设计来改进机架的应力分布也有一定的参考价值。

Normal distribution in statistics is based on the probability density function in the form of representation, and set up a continuous random variable X, the probability density function f has the form of Figure 1, where a, b are constants and were known as the average value and standard deviation,π, e, respectively pi and natural constants, claimed that X subject to parameters a, b of the normal distribution.

正态分布在统计学中是以概率密度函数的形式表述的，设连续型随机变量X的概率密度函数f有图1中的形式，其中a、b为常数，分别被称为平均值和标准差，π、e 分别为圆周率和自然常数，则称X服从参数为a，b的正态分布。

Temperature of corresponding bar conductors is the same in both change way and distribution so as that temperature of all bars is restricted within the same value and distribution scope by decalescence of medium evaporation.

与此相应的线棒导体温度具有相同变化和分布，从而将绕组所有线棒温度以介质蒸发吸热方式限制在相同的分布和量值。

Part two is about the analysis of theoretical basis for the social assistance legal institutions,which includes their department classification,their analysis of basic concept,their theoretical support and their analysis of value,and so on.The author holds that they regulate the redistributive economic relations requiring state intervenes appropriately and reflected by the actions of social assistance,they reflect and determine the implication and distribution of the redistributive economic relations,meanwhile they reflect and determine the distribution and direction of the benefits of social assistance intervened by state appropriately.Their appearance expresses the legal connection created for the poverty phenomena between state and the poor,so these legal institutions should be classified into the department of social distributive law in economic law which reflect the essence of economic law that state intervenes the economic relations required intervention appropriately.

第二部分是社会救助法律制度的理论基础分析，其中包括社会救助法律制度部门归属辨、社会救助法律制度的基本理念剖析、社会救助法律制度的理论支持以及社会救助法律制度的价值分析等内容，认为社会救助法律制度规制了由社会救助行为所反映出来的这种需要国家适度干预的再分配经济关系，反映并决定了这种再分配经济关系的牵连和分布，同时反映和决定了在国家适度干预下相关社会救助利益的分配和流向，其出现媒介了国家和贫困者之间因为贫困现象而生成的法律关系，这一法律制度归属于经济法部门中的社会分配法律制度子部门，明显地体现着经济法的本质属性——国家对需要干预的经济关系的适度干预。
