折射

Refractors have been criticized for their relatively high-degree of residual

折射望远镜曾经因为高度残余的

I noted no astigmatism, and no issues with pinch or cooldown (things that seem endemic with medium level refractors these days).

我在观测的时候没发现有散光现象，压力和降温对观测也没有什么影响（现在只有个别中等水平的折射望远镜才会存在这类问题）。

By 1933 Zeiss had manufactured several proven refractors of the "E","A" and "AS" achromatic doublet designs, and apochromat triplets of the "U.V."

1933年，蔡司生产了&E&，&A&和&AS&等几款使用消色差镜头设计，并经过实际使用验证的折射望远镜，还有&U.V。&

Also as closer the beam come to the focus as hotter it gets. We have long time practical experience in using Herschelwedges in Refractors up to 10 diameter without additional front filter, yes its safe!

长久以来，我们在实际经验中，在大至10英吋(254mm)口径折射镜上使用Herschelwedges而不加任何前置滤滤，证明它是安全是！

Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.

使用标准配件中的K20 目镜，可以得到45倍放大率，这时候很容易看到仙女座星系，还有较小的星系M32；和60毫米口径的折射望远镜相比，114 EQ可以看清更多猎户座星云的细节；瞄准英仙座双星团，看到的星体数量更多，显得更加壮丽；对于球状星团，比如M13，甚至可以显出其中少数独立的恒星；在K20 目镜下（放大45倍）的土星显得相当小，但换成我自己的7.5毫米焦距的目镜(得到120倍)，可以轻松的看到光环在土星上的投影，甚至可以瞥见土星光环内的卡西尼缝隙。

The design principle of refractive microlens arrays with different microstructures is proposed on the basic of refractive microlens arrays fabrication using thermal reflowing method and ion beam etching technique.

探讨了通过光刻热熔法及离子束蚀刻技术制作具有不同微面型结构的折射微透镜阵列的设计原则。

So the image of love being a painful thing is still prent.

所以，过去&爱情是痛苦的&的观点，在今天的中国仍被广泛地折射出来。

This polywater, made by ex posing very fine glass capillanes to a saturated atmosphere of water vapor, was very viscous, dense and had a refractive index similar to that of glass.

通过将非常纤细的玻璃毛细管放在饱和的水蒸气中产生的这种&聚合水&的粘滞性和密度都很大，其折射系数与玻璃的相似。

Examples of such devices are polarizers and compensators,switches etc.

在研究晶体中的光传输问题时，晶体的双折射效应决定了光传输的特殊性，所以在设计光电元件时光场的矢量性质是不可忽略的。

Moreover, oriental and western features are turning Maizidian into a melting pot as for culture.

这里是一面镜子，折射的是麦子店的成长；麦子店是一面镜子，见证的是区域国际化的繁荣。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
