望远镜

Some telescopes do not use a lens at the front. They use a curved mirror at the back. A curved mirror is better than a lens in some ways.

一些望远镜的前部不用透镜，而在后面装上一个曲面镜，曲面镜在某些方面要比透镜好。

The bright star in the Cygnus X-1 system is visible with a small telescope.

天鹅座X-1系统内的蓝色亮星，用小型望远镜就能看见。

Cylindrically shaped Hubble weighs 11 tons.

圆柱状哈勃太空望远镜重量11吨。

A cystoscopy is an examination of the inside the bladder using a thin telescope passed along the urethra.

1膀胱镜检查是一个考试的膀胱内使用薄望远镜通过沿尿道。

In Danzig, Johannes Hevelius developed a refracting telescope150 feet long.

在但泽，约翰尼斯·赫维留斯制作了一架150英尺长（约46米）的折射望远镜。

Then there is Mr Bryson himself, amusing as ever, poking through the archives and memorabilia, picking out his favourite pieces, which include Newton's death mask and one of his handcrafted telescopes.

还有Bryson本人一如既往的风趣，翻遍存档文案和名人记录找出他的最爱作品，包括牛顿的死亡面具和Bryson的手工制作的望远镜。

The image is very wide with about 72 degs. apparent field of view.

88式望远镜视野开阔，视场宽度为315英尺/1000码。

Angle of view: With 60 degs. apparent angle of field, the DF and the IOR are the only wide angle binoculars in this test.

视角：在本评测中，DF和IOR有60度表现视场，是仅有的广角望远镜。

Angle of view: These are low light binoculars and one should not expect excessive wide fields of view. Closest to 'wide angle' comes the IOR with 60 degs. apparent angle, which is sufficient to avoid the tunnel-view of its contenders.

视角：这些都是低亮度望远镜，不能期望有极宽广的视角，最接近"广角"的当属有60度表现视场IOR，远离了只有管窥视野的其它两款。

The remaining three contenders display a rather narrow angle (tunnel-view), and I believe that fields as narrow as 50 degs. or less are no good choice for military binoculars, where the surveillance of large areas is among the most common applications and much easier achieved with reasonably wide angles.

其它3款表现了明显的窄视角，我认为是50度甚至更小的视场对军用望远镜不是好选择，因为大面积的监视是最常见的应用，拥有适度的宽视角更容易完成任务。

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