查询词典 refractor

For example, a small low-cost wide-field refractor like the 80mm f/5 "short tube" achromats cannot easily compete with the performance of an expensive 3 element Apochromat, nor should it be expected to. These inexpensive scopes don't generally perform as well at higher powers, but they were never designed to do so.

比如像80F5这种小的低成本宽视场折射镜和与价格昂贵的三片APO根本没法比，虽然这些廉价的镜子高倍表现不好，但是它的设计本来也不是为了上高倍。

You'll also need a diagonal and if this is your first apochromatic refractor, I'll recommend a 3-6 nagler zoom.

如果这是你的第一架复消色差折射望远镜，那么你还需要一个天顶镜。我推荐用3－6毫米耐格勒变焦的天顶镜。

Homas back is already regarded as the top performer in triplet apochromatic refractor.

MB 已被认为是最佳表现的三片镜片复消色差折射镜。

This was the apochromatic refractor.

这就是APO折射式望远镜。

The new FS series employs fully hard over-coated fluorite and low dispersion elements in an air-spaced f/8 doublet design that provides the highest contrast, brightest, and sharpest images in an apochromatic refractor today.

新的FS系列使用了完全硬镀膜和低色散透镜，两片空气间隔的透镜f/8能提供最大的成像对比度、亮度和锐度。

Although the production of relatively small achromatic and apochromatic refractor telescopes of up to 15cm, and catadioptic systems of up to 18cm, all with a variety of accessories at Jena would continue until 1994 when it was realized that Zeiss could not compete in the world market; the Zeiss "APQ" refractor telescopes optics were among the finest in the world but the inability to Zeiss to adapt these products promptly to the realities of a free marketplace assured their demise.

虽然耶拿厂可以生产相对小点口径的消色差和复消色差折射望远镜（口径最大可达15cm），还有口径最大可达18cm的反射折射望远镜系统，而且产品规格类型丰富，但蔡司在1994年还是意识到，不能在此类产品的世界市场上继续竞争了；蔡司的"APQ"系列折射望远镜产品确实属于世界顶级产品之列，但蔡司不具备在自由市场经济环境下，迅速调整改进此类产品的能力，所以决定此类产品停产。

Since the consistency of refraction measured by auto-refractor and retinoscopy was quite good in the survey in 1998, we only performed the auto-refraction after cycloplegia this study.

为了帮助工作人员熟悉工作流程、检查器械以及评价他们的工作质量，正式调查之前我们选择了207名非研究对象儿童进行了预试验和一致性检验。

After cycloplegia, NIDEK handhold automated refractor optometry results are consistent with retinoscopy optometry and phoropter subjective optometry, thus, it is a kind of valuable, convenient and reliable check tool for children refractive error.

睫状肌麻痹后，手持自动电脑验光仪验光和视网膜检影、综合验光仪主观验光有极高的一致性，在儿童屈光不正检查中是一种很有价值的、方便的、可靠的屈光检查工具。

The lens telescope, or refractor, was vastly improved when it became possible to manufacture high-quality lenses made from flint glass

透镜望远镜，或称折射望远镜，在人们能够制造出高质量的火石玻璃透镜以后得到了很大的改进。

The lens telescope, or refractor, was vastly improved when it became possible to manufacture high-quality lens es made from flint glass

透镜望远镜，或称折射望远镜，在人们能够制造出高质量的火石玻璃透镜以后得到了很大的改进。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
