Substitute teacher is our primary school principals, he is a very old man's Bugouyanxiao that he had a double eagle eye, often on the natural course of my time on the very nature, I do not like this so I stifled the atmosphere, there is a very old man in particular Habits, with his glasses, I do not know if the old flowers or short-sighted glasses, not all the glasses on the bridge of the nose through the glasses with a man he did not, his eyes with a sharp nose, the man's time Head, above the framed glasses from the preview, this action has been very much afraid of me, the more quiet at a time when I knew that he would not issue a noise, and then the eagle eyes of my immediate aim, and then we all turned to see me ...... And for a long time ago, more and more like I do not like him, and he would seem to have any grudges against me more and more quickly verify my guess.

代课老师是我们的小学校长，他是一个很不苟言笑的老头子，他有一双鹰的眼睛，每每上自然课的时候我就很不自然，我不喜欢这个让我窒息的气氛，老头子有一个很特别的习惯，他带着的眼镜，不知道是老花还是近视的眼镜，不像大家把眼镜带着鼻梁上透过眼镜看人，他不，他把眼睛带着鼻子尖上，看人的时候低着头，从眼镜框子的上面瞄，这样的动作让我一直很惧怕，越在安静的时候我会发出不自知的噪音，然后鹰的眼睛马上就瞄准了我，然后大家都会扭头看我……久而之久，我好像越来越不喜欢他，他也好像也越来越跟我有仇，很快就验证了我的猜想。

In view of the demand of computerized eye-glasses-wearing system, an approach to match two dimensional (2D) human head images with 3D glasses frame graphics in 3D space has been proposed. First, the operator points out three or six key points, which are used to locate 3D eye-glasses frame, on the human face image displayed on the computer screen interactively.

论文针对计算机化眼镜配戴系统的要求，提出了一种在三维空间匹配二维人头图象和三维眼镜图形的方法，即通过人机交互方法，由操作者在显示于计算机屏幕上的二维人头图象上，指出确定三维眼镜位置的三个或六个关键点的二维坐标及其三维对应点，从而可以近似求出人面朝向及视点坐标，再用相应位置上的三维通用人头图形替换二维人面图象，计算人面和眼镜间的遮挡关系并显示，从而完成二者的空间匹配。

The results of Raman, SEM and EPMA tests show that the microstructure defects of the chalcogenide glasses play an important part in their second-order nonlinear optical properties. The glasses show large SNOP because of Sb2S3 microcrystal or the mental antimony in the glasses even before they were polarized. After the electrical/thermal polarized, GeSbS glasses show larger SNOP with the increase and growth of the microcrystal. The glasses show larger SNOP because of the existence of Sb2S3 microcrystal or the mental antimony in the glasses.

通过研究玻璃的拉曼光谱、扫描电镜和电子探针显微分析后发现，硫系玻璃内部的微结构缺陷对其二阶非线性光学性能有显著影响，玻璃体系内存在的Sb2S3微晶或金属锑颗粒能使硫系玻璃在未经极化处理前就具有较大的二阶非线性光学性能；经电场温度场极化处理后，随着微晶的增多和进一步长大，导致GeSbS玻璃具有更高的非线性光学性能；由于Sb2S3微晶或金属锑的存在，导致玻璃具有较高的二阶非线性光学性能。

X=0, 11, 22, 33, 44, and 55 borophosphate glasses series have investigated, and it is found that:(1) both the covalency bonding between Yb〓 ion and oxygen ion and the asymmetry in local structures surrounding Yb〓 ion have strong effects on integrated absorption cross section ∑〓 and emission cross section σ〓 of Yb〓 ion in borophosphate glasses;(2) the borophosphate glasses and borate glasses appear superior as Yb-gain media to the phosphate glasses, although the phosphate glasses have been demonstrated as the most appropriate Ndgain media.

在第二章中，我们对〓（x=0，11，22，33，44，和55）系列的掺Yb〓硼磷酸盐玻璃的吸收光谱和发射光谱特性进行了研究，结果表明：（1）在硼磷酸盐玻璃中，Yb-O键的共价键成分和Yb〓离子周围的近邻结构的对称性两个因素对积分吸收截面∑〓和受激发射截面σ〓的影响都很大；（2）尽管磷酸盐玻璃是最合适的掺钕激光增益基质，但是作为掺镱的激光增益基质，硼磷酸盐玻璃和硼酸盐玻璃都要优于磷酸盐玻璃。

The transmission ratio exceeded 95% in near-infrared range, so the LCAS:Tm(superscript 3+) glasses can be used as high transmission optical glasses. The integral emission cross-sections outclassed 10^(-18)cm, the fluorescent ratios were higher and the radiative lifetimes were lenger, to the glasses are possible to be used as new laser function materials. The new strong and broad emissive bands for 400nm to 680nm emerge in the emission spectra of the another glasses samples.
