望远镜

One of the principal advantages of the reflecting glass is its complete freedom from chromatic aberration.

反射望远镜主要优点之一是它完全没有色差。

Since their introduction in the early 17th century, refractors have suffered from one major defect: chromatic aberration.

色差是折射式望远镜自18世纪初推广以来所具有的主要缺陷。

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light-years, which has already been observed by ground-based telescopes, and a previously unseen ring of diameter 260 light-years.

在圆规座的漩涡星系中的大部分气体都与两个具体的"环"有密切的联系。那个较大的，直径大约有1，300光年，它已经被地基望远镜观测到了。而先前，我们没有观测到的那个小"环"，直径大约有260光年。

Now an international team of astronomers has finally observed the acceleration of protons within a shock wave. Using the Very Large Telescope in Paranal, Chile, and NASA's Chandra spacecraft, they measured the visible light and x-ray emissions of the remnant of a supernova about 8200 light-years away in the direction of the constellation Circinus.

现在，一个由天文学家组成的跨国研究小组终于观察到激波内部质子的加速情况，他们利用智利帕拉纳尔的甚大望远镜和美国国家航空航天管理局的钱德拉太空船，测量到了圆规座方向大约8，200光年处一颗超新星残骸发出的可见光和 X 射线。

具有抛物面主镜和双曲面次镜的一种折射式望远镜；光线被集中到主镜中心的孔径。

Subsequent, longer exposure observations indeed show that the lenticular galaxy is surrounded by a clumpy, never-before-seen ring of stars.

由于地球大气层会吸收紫外线，捕捉紫外线的太空望远镜必须在外太空中运转。

CMG possesses many advantages such as large output torque, small size, lightweight, and better control performance.

为BST望远镜克服吊篮在水平面内摆动的影响提出了控制回路的补偿函数的设计方法。

One of my last thoughts was of the captain, who had so often strode along the beach with his cocked hat, his sabre-cut cheek, and his old brass telescope.

最后想到的是船长，他总是沿着海滩跨着大步往前走，我想起他的三角帽，他面颊上的刀疤，还有他的旧黄铜望远镜。

Schorr had become interested in Schmidt's horizontal mirror and coelostat telescope and ordered one to be built for his observatory.

schorr已成为有兴趣在施密特的横向一面镜子， coelostat望远镜，并下令一要兴建，他天文台。

As a coelostat, MA tracks the motion of celestial objects observed at their meridian passages.

MA 作为定天镜跟踪天体的运动，望远镜在天体中天前后进行观测。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
