The result indicates that the output power oscillates and weakens along with increasing input power,and its oscillation period depends on the distance between the medium and beam focal point.Limiter′s limiting ability will decrease if waist size of the incident Gaussian beam and the aperture size increase.With a fixed input power scope,medium′s best limiting position will move towards the focal point if waist size of Gaussian beam and the aperture size increase,but the best limiting position will change a lot with different input power scopes.

结果表明：限幅器的出射功率随入射功率的增加衰减振荡，其振荡周期取决于介质相对于光束焦点的位置；限幅器的限幅能力随入射光束腰半径和光阑孔径的变大而减弱；入射功率范围固定，入射光束腰半径和光阑孔径增大时，介质的最佳限幅位置向入射光束的焦点靠近，但是在某些入射功率范围内会存在多个最佳限幅位置；光限幅器的箝位输出功率随光阑线性透过率的增加存在线性增加和非线性增加两个不同区域，实际应用中应在线性增加区域确定光阑孔径的大小。

People always eradicate and polish old wall during the reconstructing of old houses, and they often use angle grinding machine to polish old metope manually , labor intensity is very great and the wall is not even after polishing .this paper designs a metope-polishing robot, it can polish old metope automatically ,it substitutes order polishing of machine for out-of-order polishing of manpower ,so it can improve labor circumstance and prevent from polluting environment, and it can improve the efficiency remarkably and alleviate labor intensity of manpower.

在旧房改造时通常要对旧墙面进行铲除抛光，目前普遍使用角磨机进行人工打磨，其劳动强度大，打磨后的墙面不平整。本文设计出了一种墙面抛光机器人，它可全自动的实现对旧房墙面的打磨抛光，以机器的有序抛光代替人工的无序抛光，改善了劳动环境，防止了环境污染，并可大幅度提高效率，减轻人工劳动强度。

EL company owned by the production technology is imported from the United States, and engineering and technical personnel after several years of continuous research and development, improve and increase the current production of luminescent EL-has been widely used in watches and clocks, backlight, LCD backlight modules, Instruments, meters panel backlighting, remote control, PDA, cell phone backlight, fire exit routes backlight, night-light, and through the surface rich in color and flashing circuit to become animation and advertising, the ideal gift toys decorated backlight.

But the sun's rays then reach us despite having passed, first, through an enormous thickness of the higIT strata of the air, the minute dust of which reflects maximum of the higIT strata of the air, the minute dust of which reflects maximum of the blue rays away from us, leaving the complementary yellow light to pass on, Then, the somewhat coarser dust reflects the green rays, leaving a abundance orange-coloured light to pass on; and finally some of the yellow is reflected, leaving almaximum pure red.

这就充分呈现了低空尘埃的数量之大。但是太阳的光线终于到达了地面。它们先是穿过厚度极大的高空大气层，其中的细微尘埃把大部份蓝色的光反射掉了，让补色的黄光继续通行。然后，粗粒尘埃又反射掉绿色的光，让偏橙色的光继续通行。最后，部份黄色的光也反射掉，剩下几乎是纯红色的了。

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.

交际能力和语法的关系应该是目标与途径的关系。
