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。

When the elements required for a rhetorical situation are available,"the South-China Tiger Incident" has become a rhetorical incident triggered by an exigence, which is changed with the varied attitudes of the audience, who are influenced by "logos" and "ethos", as maintained by classical rhetoric.

Management Information System is a collection of information technology, economic management theory, statistics and research, database integration technology for the integrated system is a capital-and technology-intensive and labor-intensive, intellectual-intensive projects. China has a vast market and abundant human resources, technical accumulation and decades of accumulated experience, a certain advantages. Mis innovation can not sell, not self-assertive. We should seize the current favorable opportunity to network economy, China''s information technology and to achieve a leap forward of the information industry, give better play to the information industry to stimulate economic growth.

20世纪以来，社会生产力迅速发展，科学技术突飞猛进，人们进行信息交流的深度与广度不断增加，信息量急剧增长，传统的信息处理与决策的手段已不能适应社会的需要，信息的重要性和信息处理问题的紧迫性空前提高了，面对着日益复杂和不断发展，变化的社会环境，特别是企业间日趋剧烈的竞争形势，一个人、一个企业要在现代社会中求生存，求发展，必须具备足够的信息和强有力的信息收集与处理手段。

The results showed that the TiN andN films are polycrystalline phase. The properties and structure of TiN films are mainly determined by the N2 mass flow rate, and as the N2 mass flow rate increases, the structure of the TiN films transforms to f.c.c. type leading to better the properties of films. The presence of negative bias voltage can optimize the grain of TiN films, lower the defect proportion and denser the films, which improves the hardness of films. The TiN films conform to the free carrier absorption mechanism and there are many of free electrons with lower N content in TiN films. With the increase of N content, the quantity of free electrons and reflectivity of films decrease, and the plasma frequence shifts to the lower energy, which leads to the regular change of colors of films from silver, yellowy, golden to yellow-red, meanwhile the lightness of films decreases. The goldenN film consists of TiN and ZrN phase, but belongs to a sigle f.c.c. structure with (111) preferred orientation. The Zr-doping dosen't change the position of the valance band, conduction band and forbidden band ofN film, but leads to the presence of new energy levels, which is the reason thatN film remains golden. The transparent hard films with good corrosion resistance and high hardness have been prepared and the further reseachs showed that the grain size of those films is by far smaller than the wave length and the width of forbidden band of those films is very broad, is the reasons that those films are transparent.

研究表明：氮化钛和N 薄膜为多晶态，氮流量决定了氮化钛薄膜的结构和性能，增加氮流量能使氮化钛薄膜的结构向面心立方结构转变，从而得到性能良好的氮化钛薄膜；施加负偏压能优化氮化钛晶粒和减少薄膜中的缺陷，使膜层变得更致密，从而提高薄膜硬度；氮化钛主要遵循自由载流子光吸收，氮含量较少时薄膜中的自由电子数目较多，随着氮含量的增加，薄膜中的自由电子数目不断减少，反射率逐渐降低，等离子体频率向低能端移动，从而使薄膜颜色出现规律变化，由金属色银白色到淡黄、金黄再到红黄，并且薄膜亮度呈下降趋势；金黄色的N 薄膜中存在TiN 和ZrN 的分离相，但其为单一的面心立方结构并具有(111)面择优取向；相对于TiN 薄膜，Zr 掺杂后，并没有使薄膜的导带、价带和禁带发生变化，只是在TiN 禁带内增加了新能级，这也正是掺杂Zr 后，薄膜仍
