阿基米德

When Archimedes discovered the principle of specific gravity by observing his own displacement of water in a bathtub, he leaped out with delight, shouting,"Heureka, heureka!""I have found it, I have found it!"

当阿基米德从观察自己身体在浴缸中排水的现象中悟出比重原理后，他兴奋地跳出浴缸，高喊&我发现了，我发现了！&

We assumed that there were forces of attraction between molecules which varied rapidly with the distance so that the attraction between molecules that were more than a few ten millionths of a millimeter apart was very small but became c**iderable when the molecules approached more closely.

当固体浸没到液体中时，固体会失去它所排出的液体的那部分重量，这就是现在通常所谓的阿基米德原理。有关这一发现的故事说法众多，下面的故事就是其中之一。

Depending on the type of sailboat, often the weight of the ballast can be 30% or 40% of the total displacement of the boat. Heeling of the monohull will create water drag and will create necessity of a wider hull beam that will also in turn limit the speed, thing that was remarked by Archimede 220 years ago.

取决于船只的不同类型，通常压仓物的重量为船排水量的30%。220年前，阿基米德就曾指出过，独体船的倾斜会产生拖水现象和更宽的单体宽度，这样会导致速度受限。

Then some scholars believe the existence of the DEA model involving the Non-Archimedean infinitesimal and others do not.

对于含非阿基米德无穷小量DEA模型，学者分成了两派，一派肯定它的存在性，另一派否定它的存在性。

After 3800 Death of the World's top math problems -- Ruler as "arbitrary angle trisection, turning round to square, fold the cube, as is 7-gon, as is 9-gon, as are 10 side of the form, as are 13-gon," The world, where people called mathematicians have challenged the "seven problems" Archimedes Newton Gauss, etc., Are hard to understand in the end.

历经3800年世界顶级数学死题——尺规作&任意角三等分、化圆为方、倍立方体、作正七边形、作正九边形、作正十一边形、作正十三边形&，全球，凡称得上数学家的人都曾挑战过这&七大难题&，阿基米德、牛顿、高斯等等，均以不得其解而告终。

An assessment of hydropower potential and environmental impact is vital to a decision whether it is feasible and valuable to reinstall a waterwheel, a turbine or an Archimedian screw for Gordleton Mill on the Avon Water, New Forest District, England.

摘 要：水能和环境影响的评估，对于判别英格兰新福里斯特区埃文河Gordleton磨坊重新安装一台改良水车或一台水轮机或一台阿基米德式螺旋水轮机的可行性和经济性是至关重要的。

He asks Archimedes appraisal crown is bullion, but forbid bang up crown.

他请阿基米德鉴定王冠是不是纯金的，但不准弄坏王冠。
