查询词典 refractors

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）。

Refractors are unstable or even missing in the middle and there is an abnormal near surface belt in the east.

中东某稀疏三维工区表层条件复杂，工区中部折射层不稳定且部分缺失，工区东部有一地表异常区带，模型静校正和折射静校正都未能很好地解决该区的静校正问题。

Since our telescope mirror has an edge the impinging starlight gets diffracted at this edge of our telescope mirror (refractors do this to!).

同理，我们镜子的反射镜也有一个边，在这里也会造成衍射。

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。

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.
