Eu/Tb codoped aluminoborosilicate glasses were fabricated by high temperature melting-quenched technique and their luminescence properties were investigated by excitation and emission spectra. Under 376 nm excitation, blue, green and red emission

南京信息工程大学　 实验（实习）报告 实验目的：练习图形几何变换的算法及实现 实验内容：给定多边形P的控制点为：{{-3,5},{-3,2},{2,-2},{2,1}, {6,2},{2,6}},对该多边形进行二维几何变换并画出变换后的图形。 实验要求： 1、　　试将坐标原点移动到多边形P的重心； 2、　　将多边形P绕(2,-2)点顺时针旋转60度； 3、　　将多边形P分别向x方向错切2倍，向y方向错切1/2倍； 4、　　撰写实验报告并附上所用变换矩阵、程序
