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。

Methods Fourty subjects, 20 anisometrope and 20 emmetrope, the AMP accommodation lag and NRA/PRA were measured after the distance refractive correction.

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。

After relection by wall,the light of projector in floodlighting is sent out to sky and causes light pollution larger and larger.

不断涌现的现代化建筑外表的镜面光泽度较大，使得泛光照明中投光灯的光经墙面反射后射向天空形成的光污染影响越来越大。

Development strategy and advantage integration measures of domestic sander products are discussed, the gap between the sander industry in China and international advanced level, the problems with the sander production in China as well as irrational distribution of product structure are pointed out and the gap between the sander product series in China and those in Germany are analyzed.

论述了国产砂光机产品的开发策略与优势整合措施，指出我国砂光机产业与国际先进水平的差距、砂光机生产存在的问题及产品结构分布极为不合理现状，分析了我国砂光机产品系列与德国的差距。

In this paper, by using the method of expanding the hard-edge aperture function into a finite sum of complex Gaussian functions, the recurrence propagation expression for the propagation of partially coherent beams through a multiple apertured ABCD optical system is derived, which provides a fast algorithm for simulating the propagation of partially coherent beams through hard-aperture optics.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
