论文摘要：研究了光的磁场在光与介质相互作用中的行为，建立了电子云导体模型：介质中一个电子的电子云可以看作一个微小导体，光变化的磁场与电子云导体间的电磁感应作用导致光与电子云导体之间能量交换。

选取40位受试者，正视者右眼20只，屈光参差者20位，其中屈光参差者高度数眼20只，屈光参差者低度数眼20只，在屈光完全矫正的基础上用主观的测量方法测量其调节幅度、正负相对调节和调节滞后量。

When the power was 40J/cm2, the situation was similar to that with 30J/cm2 but more severe.CONCLUSION:① the blue light intensity in 30J/cm2 and 40J/cm2 could both induce the acute retinal light injury,② AcrySof one piece IOL and other PMMA IOLhave no obvious effect no retina comparing to direct eradiation,③AcrySof Natural can weaken the injury of blue light to some extent.

30J/cm2与40J/cm2蓝光光照强度均可造成新鲜离体猪视网膜的急性光损伤；Acrysof一片与直接光照相比对视网膜的光损伤形态学没有明显改变：Acrysof Natural与Acrysof一片相比具有减弱光损伤的作用。

Results based on experiment and measurement data indicate that, when 244 nm argon ion laser emits 40 mW UV light, the curve of refractive index changes in single mode hydrogen loading fiber is exponential type (Ac=1.632×10-6 t 0.76912), exponential growth is obvious in the beginning, a very good linear region is following, and then refractive index increments reach saturated.

结果表明， 244 nm氩离子倍频激光器输出光功率为40 mW时，普通载氢光纤光致折射率变化量随曝光时间总体上呈现指数分布关系Ac=1.632×10-6 t 0.76912；在曝光时间较短时，造成的光栅强度较弱，光致折射率变化量有明显的指数增长趋势，之后是一段较好的线性区域，这时两个测量模型的结果得到了很好的印证，随着曝光时间的继续增加，光致折射率变化量达到饱和。
