查询词典 rectangular prism

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。

Since 1988, the phase-correction coating (also called P-coating) was implemented, which shifted the level of contrast to that of the better Porro prism binoculars. The present sample was made around that time and already contains the P-coating.

从1988年起，phase-correction 镀膜被应用，相对更好的保罗棱镜望远镜的镀膜，它拉近了等级，当前样品就是那时生产的并且使用了P镀膜。

A unique 946 nm and 473 nm single-frequency non-planar ring cavity constituted of a thermally bonded Porro prism and a corner cube is proposed .

提出并实现了由热键合直角棱镜与角锥棱镜构成的新型946 nm及473 nm单频非平面环形激光器。

Whoever is searching for a current line high end 8x50 will probably fail to find a decently priced Porro glass, but end up with a roof-prism design such as Leica's Ultravid or Swarovski's SLC and will have to pay a premium.

谁若在搜寻当前生产的高端8x50，将无法找到合适价格的保罗镜，只能找到屋脊镜如Leica's Ultravid或者Swarovski's SLC，并且要付出更多费用。

When Zeiss Jena in 1985 introduced a new high-end line of Porro Prism binoculars, which originally included the 8x50 Octarem and the 12x50 Dodecarem, they did something very smart: They returned back to the classical design with a long body shape, allowing for longer focal lengths and therefore relaxing the technical requirements inherent in the Nobilem Super without the need to sacrifice optical performance.

1985年Zeiss Jena生产了一款新的高端保罗望远镜，最初包括8x50 Octarem和12x50 Dodecarem，它们在下面事上做的很聪明：返回到了长身躯的传统设计，允许更长的焦距，于是放宽了Nobilem Super固有的技术要求，也不需要牺牲光学性能。

By thermally bonding the YAG crystal with 2 mm thick Nd∶YAG crystal,the Porro prism supplies multi-functions such as laser amplification,closuring the light path,polarization sensitivity to the 946 nm and so on.

直角棱镜由无掺杂的YAG晶体和2 mm厚的Nd∶YAG晶体热键合形成，可提供激光增益、光路闭合及对946 nm激光起偏等多种复合功能。角锥棱镜由熔融石英材料构成，在环形永磁铁作用下，提供法拉第旋转作用。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
