笼效应 meaning in English

cage effect

By using dta , ir and xrd analysis , the result show that : in the gel glass of these two system , the phase change of the zirconia and the alumina are restricted because of the high content of silica which leads to the stabilization of the prepared materials . and the applications of these two materials is introduced briefly . by using absorption spetrum and fluorescence spetra analysis , the result show that : in the gel glass of the nd - doped sio2 - al2o3 gel bulk glass - ceramic , the strongest emmision is at about 1 . 06u m , the clustering of nd3 + ion is controlled by the addition of alumina which creates the " cage effect " to nd3 + ion
同时分别对凝胶进行了dta 、 ir 、 xrd分析，结果表明：对于此两个系统的凝胶玻璃-陶瓷，由于二氧化硅含量较高，使得氧化锆及氧化铝的相变受到约束，从而保证所制备材料的稳定化，同时对两种材料的应用也作了简单介绍；对掺钕sio _ 2 - al _ 2o _ 3激光玻璃-陶瓷进行了荧光及吸收光谱分析，结果表明：钕铝共掺杂二氧化硅玻璃的最强发射处于1 . 06 m左右，加入的少量氧化铝使钕离子产生“笼效应” ，阻止钕的团聚。
