Methods Retrospectively analysis 32 cases (32 eyes) of primary retinal detachment which had accepted surgery under indirect ophthamoscope with no hand-held condensing lens.

回顾性分析32例32眼原发性视网膜脱离术中局部巩膜抵压法压陷后，不用手持聚光透镜而在间接检眼镜直视下进行巩膜外冷凝、垫压或环扎手术，临床观察统计手术效果。

Chimney for high strength, thermostable Philippine your glass lens, condenses the effect well, the radiation distance is farther, is the aviation obstruction light first choice.

灯罩为高强度、耐高温的菲涅尔玻璃透镜，聚光效果更好，辐射距离更远，是航空障碍灯的首选。

Otherwise, we design several shapes of the TFT devices, like symmetry structure、non-symmetry structure、differential channel width and length of the TFT devices、micro lens array lie on top of the TFT devices.

除此，利用不同的薄膜电晶体光感测元件设计，如对称式的、非对称式的、不同通道的宽度及长度或是电晶体上方制作微小的聚光透镜等方式。

The results show that the maximum resultant displacement of the Fresnel lens occurred at the corners of the arrays of photovoltaic concentrators for the given HCPV system at all elevation angles.

模拟分析结果显示，对於给定之聚光型太阳能发电系统在任何仰角中，聚光透镜最大之位移量将发生於各个集光器角落之聚光透镜上，并随著风速的增加而增加。

Ed spot/projector light adopt foreign high power led bulb,it is equipped high-efficiency Condenser lens,beautiful Lamp shape,High-brightness, Low power ,Low calorie,Impact resistance,shakeproof,lifespan is can be 2000 hours long.

ED投光灯采用进口大功率LED，配有高效率聚光透镜，精美的灯具外型，具有高亮度，低能耗，低热量，耐冲击，防震，无紫外和红外辐射，低电压下工作安全可靠，寿命长达20000小时。

Fresnel lens is a lens branch, as it compared with other lens is small in size, light weight, the advantages of compact structure. At the same time, it will have no worse than other lens in Condenser and imaging performance. Therefore, it is widely used in various fields such as defense, aviation, space, industrial production and civilian.

菲涅尔透镜是透镜的一个分支，由于它同其他的透镜相比，具有体积小，重量轻，结构紧凑的优点，同时它拥有不逊于其它透镜的良好聚光性和成像性能，因此在国防、航空、空间、工业生产和民用等各个领域获得广泛的应用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
