折射

Apochromatic refractors''' have objectives built with special, extra low-dispersion materials.

高度消色差折射镜'''使用特别的材料，特别低色散度的材料，来制造物镜。

It happened that we just had a Thomas Back 7 inch Apochromatic Triplet telescope by the side and so we AB compared the performance of the TMB and Maxivision.

我们刚刚有了一枝 Thomas Back TMB 7 英吋口径 f/8 复消色差折射镜在一起作此对比测试。

The new apochromats were rare instruments, however, as totally apochromatic reflectors began to dominate astrophotography.

然而，当这种新型复消色差镜还是很稀罕的时候，真正的全消色差折射镜正将主宰天体摄影领域。

Takahashi also makes observatory telescopes which include: 350mm hyperbolic astrographs, 300 and 400mm Cassegrains, 200, 250 and 300mm triplet apochromatic refractors and the large EM-3500 mounts to carry them.

高桥也制造天文台用的350mm双曲面镜，300和400mm的Cassegrains， 200，250和300mm的三片APO折射镜以及支撑它们的大型EM-3500赤道仪。

An arc of colored light in the sky caused by refraction of the sun's rays by rain .

雨后由于阳光的折射而引起的天空中的带有彩色光的拱。

One of the beauties of art is that it reflects an artist's entire life.

艺术的魅力之一在于它折射了一个艺术家的一生。

Towards the end of the 19th century, just as reflecting telescopes were coming into favor with professional astronomers, a new type of refracting telescope was built for the new field of astrophotography.

20世纪末，反射式望远镜正被专业的天文学家所青睐时，一种新型的折射式望远镜为天体摄影学制造出来。

In a special case when the boundary is perpendicular to one asymptotic line of the hyperbola, phase matching can not be achieved unless the 1DLHM is regarded intrinsically lossy.

在具有双曲线色散特性的一维各向异性异向介质界面上，当双曲线的渐近线垂直于界面时，平面波的折射反射行为只有在介质被考虑为有损的情况下才能得到合理的解释。

Attenuation induced by rain is prediceted with the equivalent complex refraction constant. The attenuation predicted is nearly consistent with that calculated by the formula recomended in ITU-R and measured results, which testifies that the method used in that paper is effective.

然后，利用所得公式计算得到的等效复折射指数预测了降雨衰减率，预测值与ITU-R推荐公式计算结果及实测值基本符合，说明文中所使用的方法是有效的。

If a P wave refracts out of the rock surface into the air, and it has a frequency in the audible range, it will be heard as a rumble.

如果一个P波折射出的岩石表面到空气中，它有一个频率的发声范围，这将是作为一个听到隆隆。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
