望远镜

The beam conversional properties of Gaussian beams through a telescope-lens system were deduced based on parameter q and ABCD law.

During the total eclipse of Epsilon Aur, 18 and 6 spectra in the Hα region were taken in rapid succession on March 9 and 10, 1983 respectively by use of the Beticon at the Coude focus of the McDonald Observatory 2m telescope.

用美国麦克唐纳2.7米望远镜折轴分光仪的Reticon对H_α附近光谱区进行连续18次(3月9日)和6次(3月10日)观测，用计算机绘图和处理，得到了金属线的视向速度，H_α线的轮廓、视向速度、等值宽度的短时标变化。

But when the telescope is dallying at a specific point in the sky, there is no point in recording on a single frequency for an extended period of time.

当望远镜在空中某个特定方向上停了下来，在一个频率上记录一大段时间就没什么用处了。

But I was not content with this Discovery; but having now more Courage, and consequently more Curiosity, I takes my Man Friday with me, giving him the Sword in his Hand, with the Bow and Arrows at his Back, which I found he could use very dextrously, making him carry one Gun for me, and I two for my self, and away we march'd to the Place, where these Creatures had been; for I had a Mind now to get some fuller Intelligence of them: When I came to the Place, my very Blood ran chill in my Veins, and my Heart sunk within me, at the Horror of the Spectacle: indeed it was a dreadful Sight, at least it was so to me; though Friday made nothing of it: The Place was cover'd with humane Bones, the Ground dy'd with their Blood, great Pieces of Flesh left here and there, half eaten, mangl'd and scorch'd; and in short, all the Tokens of the triumphant Feast they had been making there, after a Victory over their Enemies; I saw three Skulls, five Hands, and the Bones of three or four Legs and Feet, and abundance of other Parts of the Bodies; and Friday, by his Signs, made me under stand, that they brought over four Prisoners to feast upon; that three of them were eaten up, and that he, pointing to himself, was the fourth: That there had been a great Battle between them, and their next King, whose Subjects it seems he had been one of; and that they had taken a great Number of Prisoners, all which were carry'd to several Places by those that had taken them in the Fight, in order to feast upon them, as was done here by these Wretches upon those they brought hither.

我做出一想到这种罪恶勾当就要呕吐的样子。然后，我向他招手，叫他马上走开。他立即十分驯服地跟着我走了。我把他带到那小山顶上，看看他的敌人有没有走。我拿出望远镜，一眼就看到了他们昨天聚集的地方。但那些野人和独木舟都不见了。显然他们上船走了，并且把他们的两个同伴丢在岛上，连找都没有找他们。我对这一发现并不感到满足。现在，我勇气倍增，好奇心也随之增大。因此，我带了我的奴隶星期五，准备到那边看个究竟。我给了他一把刀，让他拿在手里，他自己又把弓箭背在背上--我已经了解到，他是一个出色的弓箭手。另外，我还叫他给我背一支枪，而我自己则背了两支枪。这样武装好之后，我们就向那些野人昨天聚集过的地方出发了，因为我很想获得有关那些野人充分的情报。一到那里，呈现在我面前的是一起惨绝人寰的景象，我血管里的血不由得都冰冷了，连心脏也停止了跳动。那真是一幅可怕的景象，至少对我而言实在惨不忍睹，可是对星期五来说，根本不当一回事。那儿遍地都是死人骨头和人肉，鲜血染红了土地；那大片大片的人肉，有的吃了一半，有的砍烂了，有的烧焦了，东一块西一块的，一片狼藉。总之，到处都是他们战胜敌人之后举行人肉宴的痕迹。我看到一共有三个骷髅，五只人手，三四根腿骨和脚骨，还有不少人体的其他部分。

And the diffractive telescope can satisfy these requirements.

衍射望远镜可以满足上述要求。

A rotating tube, which can turn in its cradle to orient the eyepiece more where you prefer, is therefore a nice plus in a small reflector and almost mandatory in a large equatorially mounted one.

一个可旋转的目镜盘会带来许多便利，因此它已几乎成为了望远镜的必备附件。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
