折射

Luminaire using reflection and/or refraction to increase the luminous intensity within a limited solid angle.

在限定的立体角内采用反射或折射法提高光强的灯具。

The sonobuoy permits recording a refraction profile with only one ship.

声纳浮标允许只以一艘船来记录折射剖面。

Since 1982, the Institute of Oceanology, Chinese Academy of Sciences has conducted more than 20 sonobuoy refraction measurement in the area of East China Sea. In 1991, the IOCAS also conducted OBS measurement in the same area.

1982年以来，中国科学院海洋研究所在东海海域进行了二十多个站位的遥测浮标折射地震测量，1991年又在东海陆架区进行了OBS测量。

Sutpen's initiative journey, on which a boy denied of entry to a manor through a front door is shaped into a social cooperator of that caste society, mirrors the unique social development of the South, and his cognizance and identification of southern social structure reflects a boy's default of self-identity and defects of American Southernness.

中萨德本由一个富人门前"被拒绝的孩子"转变为"社会的合作者"的出行之路，实质上是对南方独特的社会发展历程的重新再现，他在路上的成长经历以及所表现出来的对南方社会的认知和认同，折射出一个南方少年"自我"身份的缺省和美国"南方性"的缺陷。

Since Kurosawa's samurai adventure "Yojimbo"(1960) was remade as "A Fistful of Dollars" and essentially created the spaghetti Western, and since this movie and Kurosawa's "The Hidden Fortress" inspired George Lucas'"Star Wars" series, it could be argued that this greatest of filmmakers gave employment to action heroes for the next 50 years, just as a fallout from his primary purpose.

自黑泽明的武士历险影片"用心棒"被翻拍成"荒野大镖客"以来，从中提炼创造出了意大利面条式的西部片，同时，这部电影和黑泽明的"战国英豪"，启发了乔治。卢卡斯，后者拍摄了"星球大战"系列，因此，有理由相信，这位最伟大的电影导演在下一个50年里，除了为众多动作明星提供在银幕上一展身手的机会外，还有，他的首要目标折射出的光芒，影响着一代又一代电影人。

The spectral property of the uniform fiber Bragg grating in the high-birefringence photonic crystal fiber are studied.

研究了具有高双折射的光子晶体光纤中均匀布拉格光栅的光谱特性。

On the basis of analyzing the principles of interleaver filters of the interference of polarized light and planar lightwave circuit-type lattice structure, the equivalent mathematical representation of the spectral transmittance of the two kinds of interlearers is revealed. The equivalent relationships of the structural parameters of them are given.

在分析比较双折射晶体偏振光干涉型和平面波导环形格子结构型光交错复用滤波器原理的基础上，揭示了两者在光谱透射率的数学上的等效性，给出了两者结构参量之间的等效关系，可以直接利用经简单傅里叶级数对比法获得的晶体的结构参量对平面波导环形格子结构型光交错复用滤波器进行结构设计。

This is a diffuse phenomena, its specular equivalent would be something like transparency or refraction.

这是一个漫的现象，它会像镜面等于或折射透明度。

METHODS: The mean preoperative spherical refraction was -3.66 diopters and the mean cylinder was -0.66 D for all eyes.

全部眼睛的平均术前球面折射为-3.66屈光度和平均散光为-0.66 D。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
