棱镜

The visible spectrum of Mg-based alloy was studied with grating spectroscope and prism spectroscope based on simulated spectrum.

在计算机模拟基础上使用光栅看谱镜和棱镜看谱镜对镁合金基体及成分元素的可见光谱进行了分析，摄制了彩色图谱，研究了镁合金看谱分析方法。

The optical systems often consist of the optical accessories of the lens、prism、spectroscope、reflector and so on, their surfaces usually contain two classes which are sphere and plane.

一般的光学系统是由透镜、棱镜及分光镜、反射镜等光学零件组成，其面形通常是球面和平面两大类。

The characteristics of visible light spectrum used for spectroscopic analysis of vanadium in Ti-based alloy were investigated with grating spectroscope and prism spectroscope.

使用光栅看谱镜和棱镜看谱镜研究了钛合金中V元素看谱分析用可见光谱线特征，计算机模拟了V和Ti元素的可见光谱图，摄制了彩色图谱。

The spectroscopic analysis carried on Ni-based alloy visible spectrum with grating spectroscope and prism spectroscope and color spectrum had been taken, characteristic of visible spectrum was studied in Ni-based alloy.

摘要使用光栅看谱镜和棱镜看谱镜对镍基合金可见光谱进行看谱分析，摄制彩色图谱，研究基体元素镍和各成分元素的可见光谱特征。

Apparently, the oculars and the prism housings do not differ from the 6x30 model.

显然，目镜和棱镜室与6x30是同一规格的。

But wide angle oculars with long focal lengths have large field lenses, which require large prisms to be illuminated to the edges of the field, and this leads to an expensive and bulky instrument.

但宽视野又长焦距的目镜含有广角镜片，这需要大棱镜照亮视场边缘，导致价格昂贵和体积巨大。

Since today's trend goes towards low weight and compact binoculars, optical designers have become reluctant to offer wide fields of view which require larger prisms and expensive oculars with additional lens elements but: Check the No.

当前的趋势是低重量更紧凑的镜子，光学设计师不愿意提供大视场，这需要需要更大棱镜和更贵的需要增加镜片个数的目镜（但，核对 collected wisdoms 的第九条）。

The BPO is produced at KOMZ (Kazansky Optiko-Mekhanichesky Zavod) in the Autonomous Republic of Tatars.'B' stands for binocular,'P' for Porro prism, and 'O' stands for individual focus oculars.

BPO是位于Autonomous Republic of Tatars 的KOMZ (Kazansky Optiko-Mekhanichesky Zavod)生产的。B表示双筒望远镜，P表示保罗棱镜，O表示目镜分别调焦。

The best known is the Nicol prism, invented in 1828 by the Scottish physicist William Nicol.

最有名的是尼科耳棱镜，1828年由苏格兰物理学家尼科耳所发明。

The system is based on optical heterodyne structure, and use half wave plate, quarter wave plate and polarization beam splitter to improve the intensity of Doppler signal and signal-noise-ratio.

系统采用了外差式纵向激光多普勒测量结构，利用1/2波片、1/4波片与偏振分光棱镜相结合及外差式参考光结构，有效地提高了多普勒信号的强度与信噪比。

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。
