Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

In general, the traditional characteristics of Chinese films are as follows: the formula for artistic creation is dominated by realism; the ideographic method is inclined to conveyimplications; the narrative technique is characteristically an integrated story; the portrayal of the charaters' fate is based on dramaticism;the golden mean promotes moderate and implicit emotional exp ression; the ideology holds philosophical and instructional significance.

中国电影是我们这块土地黄皮肤子民的文化结晶，它的血液中流淌着民族挥之不去的深刻印记，搜捡中国电影艺术表现上的隐显标记，有助于现代电影的健康发展。就总体而言，中国电影传统特征包括以下几个方面：以现实主义为主导的艺术创作方法；言外之意的表意方式；追求故事完整统一的叙事性特点，以戏剧性为基础的人物命运塑造；中庸为度、节制含蓄的惰感抒情特征；充满哲理教化目的的思想倾向。

Classic rough set theory based on equivalence relation takes complete system as object of study , and divides the region into some non-intersect equivalence class; But, in the real life, because of the errors in data measuring, understanding of data, or the restriction in data collection , it can make the decision-making system incomplete, that is, value of attribution of some objects is unknown, which restrains development of the theory to practical direction.

经典粗糙集理论以完备系统为研究对象，以等价关系为基础，通过等价关系将论域划分为互不相交的等价类；然而，在现实生活中，由于数据测量的误差，对数据理解或获取的限制等原因，使得在知识获取时往往面临的是不完备系统，即可能存在部分对象的一些属性值未知的情况，这就极大地限制了粗糙集理论向实用化方向发展。

Then, the differential equations are solved by the Fourier expanding and Hankel integral transform method. Integral solutions of soil skeleton displacements and pore pressure as well as the total stresses for poroelastic media are obtained. Furthermore, a systematic study on Lamb's problems in transversely isotropic saturated half-space is performed. Integral solutions for surface radial, vertical and tangentical displacements are obtained both in the case of drained surface and in the case of undrained surface excited by vertical and tangentical harmonic resources respectively. Numerical results show the obvious difference between the model of isotropic saturated poroelastic media and that of transversely isotropic saturated poroelastic media.

其次，基于Biot波动理论，在圆柱坐标系下求解了横观各向同性饱和土的Biot波动方程：通过引入位移函数，在圆柱坐标系下将横观各向同性饱和土的Biot波动方程转化为两个解耦的6阶和2阶控制方程，然后根据方位角的Fourier展开和径向Hankel变换，求解波动方程，得到以土骨架位移和孔隙水压力为基本未知量的积分形式一般解，并用一般解给出了饱和土总应力分量的表达式；再以基本解为基础，系统地研究了横观各向同性饱和半空间体的Lamb问题，考虑表面排水或不排水两种情况后，首次得到横观各向同性饱和半空间体在表面竖向和水平谐振力作用的下径向、竖向和周向位移的解析解。

On the basis of the crystallography, however, systematic investigation on crystalline habit of oxide crystal synthesized by hydrothermal processing, including single crystals and crystalline grains in ultrafine ceramics powder, is also a noticeable subject with theoretical and applicable significance, which has been studied in this article according to plentiful data of experiments obtained in research on crystal defects in synthetic smoky quartz, preparation of amethyst quartz and ultrafine zirconia and alumina powder by hydrothermal processing.

但以结晶学为基础，较系统地研究水热条件下氧化物晶体，包括单晶和陶瓷微粉中的晶粒的结晶习性和结晶动力学仍是一个值得重视的、既有理论意义又有应用价值的课题。本文通过对水热法人工烟水晶中的缺陷、人工紫水晶的生长、水热法超细ZrO〓粉体和Al〓O〓粉体的制备等研究，以较为丰富的实验资料基础上，在这一方面进行了探讨。
