查询词典 prism

As the tetrahedral grids exist in the majority area, the pentahedral prism grids are adopted near the boundary, which meets the SST model's requirement of mesh in the boundary layer. Pressure recovery factors under different number of grids are calculated so as to decrease the error from coarse mesh, then the suitable number of grids is obtained.

流场大部分区域为四面体网格，在边界附近采用加密的五面体棱柱型网格，满足了SST模型对边界层网格的要求；为了减少网格过粗引起的汁算误差，还通过计算不同网格数下尾水管的压力恢复系数来优选出合适的网格数目。

By computer simulation, we analyze the influence of the incidence plane, incidence angle and thickness of air gap on transmittance, and the dependence of the transmittance on wavelength is given in the spectral range which is required by the instrument system using Sellmeier dispersion equation. The transmittance of Grand-Taylor prism is tested in experiment, and the results are in good agreement with the theoretical results, so the correctness of the theory is verified.

论述了自行设计研制的偏振干涉成像光谱仪的工作原理，分析了其核心部件格兰-泰勒棱镜的分光机理；运用光线追迹方法，推导出了格兰-泰勒棱镜全视场角透过率计算公式；通过计算机模拟分析了入射面、入射角和空气隙厚度对该棱镜透过率的影响，并利用方解石Sellmeier色散方程，给出了该棱镜在仪器系统要求的光谱范围内透过率与波长的关系曲线；实验测试结果与理论计算公式相符，验证了理论公式的正确性。

Because of its own figure characteristics with the plane is a triangle, the surface of the building mainly use transparent film-gilt glass to strengthen the pure feeling of the cubage and the quality, and give prominence to the own form of tri-prism.

由于塔楼建筑平面为三角形，本身具备一定的体型特点，因此建筑主体外表面主要用透明镀膜玻璃组合，加强体量的纯粹感，突出本有的三棱柱体型。

Both the polarizer and analyzer settings and the position of the prism can be varied.

偏振镜和分析器以及梭镜的位置均可变动。

General often see the combination is Porro prism series.

一般常看到的组合棱镜是Porro系列。

But the good Roof Design Series optical imaging and Porro series only, not better, but Roof prism of the more dense, relatively light weight.

不过设计的好的Roof系列光学成像只和Porro系列一样，也没有比较好，但是Roof的棱镜结构较为密实，重量比较轻。

Whether or series of Porro Roof Series, binoculars prism of this combination, its ultimate purpose is to do a series of light refraction, the final out of the light from the eyepiece for the formation of legislation is like.

不论是Porro系列或是Roof系列，望远镜的这一组合棱镜，其最终目的就是将光线做一连串的折射，让最后从目镜出去的光线形成为正立像。

I hope that once upon a time a manufacturer decides to pick up this design and produces a modern 8x50 Porro prism binocular, with a reasonable price tag (which could be around 700 Euro), and on a quality level of this old Zeiss.

我期望先前某厂家决定再启用这个设计生产现代化的8x50保罗镜，有一个合理价格（应该大约700欧元），并且质量水平和这个老Zeiss镜一样。

This is the rule of thumb for anybody who is looking for a second hand binocular with maximum performance: If it is a Porro, it should have been made after 1980 (availability of multi layer coating), if it is a roof prism, then not earlier than 1990 (phase-shift coating).

所以对二手镜子光学表现有要求的买家而言，这里有一条基本原则：要是买保罗镜，最好是1980年以后的，如果买屋脊镜，就别买1990年以前的。

Without any doubt, the Swarovski Habicht delivers the best optical performance of this competition. This is a high tech Porro prism binocular with almost perfect optics and accurate mechanics.

毫无疑问，施华洛世奇的Habicht提供了本测试最佳的光学表现，这是一个高科技保罗棱镜望远镜，拥有几乎完美的光学和精确的机械性能，它只有一个弱点：单薄的视场。

Tired of marines soldiers, firefighters and volunteers rushed to care for refugees and help trouble for the reluctance of people to small liferaft, time and again these people transported to the high ground, where other modes of transport They picked up waiting.

疲倦的海军陆战队士兵、消防队员和志愿者们赶来照顾难民，帮助麻烦的、不情愿的人到小救生筏子上，一次又一次把这些人运到高地上，其他交通工具在那儿等着接走他们。

Desirable Knowledge of surface treatments such as: paint, coat galvanizing, metalized coating, etc.

具有表面处理知识的优先，如：油漆，镀锌，金属镀膜，等。
