A pivotal problem to recognize of the precise position of laser facula has been solved in the process of design work: Firstly the method of background-subtraction is used to eliminate or weaken the affect of background light. Secondly the image threshold segmentation operation and morphologic operation are used to locate the sketchy position of laser facula ; Then the new method of Extracting Edge are designed based on character of laser facula , by using this method in the search area the edges of laser facula can be extracted effectively; At last the optimum picture of laser facular is selected by using the triggering function of hardware and function of software. The exact result can be obtained only by image processing to optimum picture.

在设计过程中解决了精确确定激光斑中心位置这一关键问题：首先利用减背景法，消除或减弱背景光的变化对确定激光光斑中心的影响；再对减完背景后的图片进行阈值分割和二值化处理以确定激光光斑的粗略位置；根据本文激光光斑的特征，设计了一个有效的边界提取算法，对指定区域进行提取激光光斑边界操作，精确的确定激光斑中心位置；最后利用硬件的触发功能和软件编程实现了激光光斑最佳图片的判读，只有对最佳图片进行图像处理得到结果才是准确的。

The management under the modernity make the chair in university become a quantitative posatition,the posation generate power through symbol,the formulable academic posation generate strong discipline power.Academic creation become a plan project,individuals face a giant engineering structure,the individual moral sensitivity ebbed away.

Academic estimation become a shortterm action.

现代性之下大学的管理使得大学的学术职位演变为一个数量化的位置，这一位置利用符号产生力量，&公式化&的学术位置制造了强大的规训力量；学术创造变成规划性工程，个人时刻面临着非个人的巨型工程结构，个体的道德敏感性泯灭其中；激励与惩罚在现代性之下分界线模糊，对学术激励的过分使用使学术激励其演化成了学术惩罚；大学内学术在货币指挥下正不断地制造差异与竞争，学术货币化；学术考核则演变成一种短期行为。

Foreign atoms were placed over the sheet at several symmetrical positions, namely, over a carbon atom, over a C-C bond, over the center of a pentagonal, hexagonal, and heptagonal ring. The following conclusions have been drawn: The cohesive energy of adsorbate and perfect sheet at all three adsorption sites is always lower than that on a sheet with a Stone-Wales defect embedded at all five sites.

得到的主要结论如下：所有外来原子在含有Stone-Wales缺陷的石墨烯片上不同位置上吸附的结合能都大于在其在完整石墨烯片上不同位置上的结合能，因此在碳管中引入Stone-Wales缺陷能够提高原子在碳管上的吸附能力，同时提供了很多稳定的吸附位置。
