小望远镜

The Galilean telescope's biggest disadvantage is its small field of view.

伽利略望远镜的最大缺点是它的视野小。

We need to observe lots and lots of stars because the probability of a geometric alignment is very small, something like one to 10 percent, she noted.

我们需要观察非常非常多的星星，因为它们对望远镜呈几何直线排列的概率非常小，也许只有百分之一到百分之十。她说。

All this Labour I was at the Expence of, purely from my Apprehensions on the Account of the Print of a Man's Foot which I had seen; for as yet I never saw any human Creature come near the Island, and I had now liv'd two Years under these Uneasinesses, which indeed made my Life much less comfortable than it was before; as may well be imagin'd by any who know what it is to live in the constant Snare of the Fear of Man; and this I must observe with Grief too, that the Discomposure of my Mind had too great Impressions also upon the religious Part of my Thoughts, for the Dread and Terror of falling into the Hands of Savages and Canibals, lay so upon my Spirits, that I seldom found my self in a due Temper for Application to my Maker, at least not with the sedate Calmness and Resignation of Soul which I was wont to do; I rather pray'd to God as under great Affliction and Pressure of Mind, surrounded with Danger, and in Expectation every Night of being murther'd and devour'd before Morning; and I must testify from my Experience, that a Temper of Peace, Thankfulness, Love and Affection, is much more the proper Frame for Prayer than that of Terror and Discomposure; and that under the Dread of Mischief impending, a Man is no more fit for a comforting Performance of the Duty of praying to God, than he is for Repentance on a sick Bed: For these Discomposures affect the Mind as the others do the Body; and the Discomposure of the Mind must necessarily be as great a Disability as that of the Body, and much greater, Praying to God being properly an Act Of the Mind, not of the Body.

现在，再接着说说我接下去做的事。我把一部分家畜安置妥当后，便走遍全岛，想再找一片这样深幽的地方，建立一个同样的小圈地养羊。我一直往岛的西部走，到了一个我从前从未涉足的地方。我往海里一看，仿佛看到极远处有一只船。我曾从破船上一个水手的箱子里找到了一两只望远镜，可惜没有带在身边。那船影太远，我也说不准到底是否是船。

About a Year and half after I had entertain'd these Notions, and by long musing, had as it were resolved them all into nothing, for want of an Occasion to put them in Execution, I was surpriz'd one Morning early, with seeing no less than five Canoes all on Shore together on my side the Island; and the People who belong'd to them all landed, and out of my sight: The Number of them broke all my Measures, for seeing so many, and knowing that they always came four or six, or sometimes more in a Boat, I could not tell what to think of it, Or how to take my Measures, to attack Twenty or Thirty Men single handed; so I lay still in my Castle, perplex'd and discomforted: However I put my self into all the same Postures for an Attack that I had formerly provided, and was just ready for Action, if any Thing had presented; having waited a good while, listening to hear if they made any Noise; at length being very impatient, I set my Guns at the Foot of my Ladder, and clamber'd up to the Top of the Hill, by my two Stages as usual; standing so however that my Head did not appear above the Hill, so that they could not perceive me by any Means; here I observ'd by the help of my Perspective Glass, that they were no less than Thirty in Number, that they had a Fire kindled, that they had had Meat dress'd.

我自从有了这些想法之后，平时就经常会想到这件事，可是因为没有机会付诸实施，因此一直都毫无结果。这样大约又过了一年半光景。一天清晨，我忽然发现有五只独木舟在岛这头靠了岸，船上的人都已上了岛，但却不知道他们去哪儿了。他们来的人这么多，把我的计划彻底打破了。因为我知道，一只独木舟一般载五、六个人，有时甚至更多。现在一下子来了这么多船，少说他有二三十人，我一个人单枪匹马，如何能对付他们呢！因此，我只好悄悄躲到城堡里去，坐立不安，一筹莫展。可是，我还是根据过去的计划，进行作战准备，以便一有机会，立即行动。我等了好久，留神听他们的动静，最后，实在耐不住了，就把枪放在梯子脚下，像平时那样，分作两步爬上小山顶。我站在那里，尽量不把头露出来，唯恐被他们看见。我拿起望远镜进行观察，发现他们不下三十人，并且已经生起了火，正在煮肉。至于他们怎样煮的，煮的又究竟是什么肉，我就不得而知了。

He sent this little instrument to the Royal Society, where it caused a sensation; it was the first working reflecting telescope.

他发出这个小文书，以英国皇家学会，在那里引起轰动，这是第一次工作反射式望远镜。

I looked through the telescope and saw a small boy with a bag over his shoulder.

我透过望远镜观察并看到肩上扛着一个包的小男孩。

Come and look through my tele scope,and you will see that I am right.

Most other radio telescopes are like telephoto lenses, zooming into a tiny region of space.

大部分其他的射电望远镜就像远望镜头一样，只能将太空中的极小一部分放大。

A method of measuring the linear expansion coefficient of metal is introduced, in which the temperature is recorded in real time with copper-constantan thermocouple instead of thermometer and the length of the metal bar is measured using reading telescope.

用铜－康铜温差电偶代替水银温度计对金属棒进行动态实时温度测量，用尺度望远镜同步读取棒长度示数，用最小二乘法进行线性拟合，从而得到金属线胀系数。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
