May 10 , 2005 ? we ' re smarter and more creative lying down than standing up , says a researcher who believes this helps to explain archimedes ' eureka moment 科学家说，我们躺下来的时候可能比站著的时候更聪明、更有创意，这可能也可以解释为何阿基米得是在躺在澡缸里的时候才想通浮力定理。
What is new is the application , which by an inversion of the energy flow in its operation , turns the archimedes screw trough pump into a power generator for the extraction of energy 水力螺旋发电机的独到之处在于对水流能量进行逆向利用，把阿基米德螺旋泵转变成一个可以从水流中提取能量的发电机。
It is interesting to note that the first calculation of the diameter of the earth was made following a nice experiment by eratosthenes , a contemporary of archimedes in the second century b . c 有趣的是，对地球直径最早的计算是由eratosthenes的一个很好的实验进行的，他生活在公元前二世纪，与archimedes同时代。
This paper develops iterative formula of sine and cosine function in document [ 40 ] , and presents new pixel - level algorithms for generating archimedes and involute curves which are widely used in engineering 本文推广了文献[ 40 ]中正弦、余弦函数的递推公式，对工程绘图中常用的阿基米德曲线和渐开线设计了新的逐点生成算法。
The development of the method of exhaustion beyond the point to which archimedes carried it had to wait nearly eighteen centuries until the use of algebraic symbols and techniques became a standard part of mathematics 几乎18个世纪以后，直到代数符号及其算法成为数学标准算法的一部分时，穷竭法的发展才超出阿基米德应用范围。
This paper researches the basic algorithms of computer graphics including the algorithms of an efficient algorithm for polygon clipping and pixel - level algorithm for generating archimedes and ivolute curve 本文的工作是对计算机图形学中的基础算法进行研究。包括一个有效的多边形裁剪算法，以及阿基米德曲线及圆的渐开线的逐点生成算法。
This paper presents the basic construction and movement rules of the coordinator gyrorotor with reticle of archimedes spiral reticule pattern , also , it explains the principles and methods of dynamical balance to damp the vibration and forced nutation 阐述了具有阿基米德螺旋线图案的位标器的基本原理及其运动规律，并说明这种陀螺转子的振动与绕动的平衡原理与方法。
Starting on july 26th , researchers at the stanford synchrotron radiation laboratory in california , led by uwe bergmann , will attempt to read the final pages of the oldest known manuscript of archimedes ' s work , the archimedes palimpsest 在尤.伯格曼的带领下，加利福尼亚的斯坦福同步加速器辐射实验室的研究人员将于7月26日尝试阅读目前所知的最早的阿基米德著作的手稿- 《阿基米德》重写本-的最后几页内容。
Lipnicki said there is historical evidence for his finding in the case of the greek mathematician archimedes , who worked out while lying in his bath that the amount of water that overflowed his tub was proportional to the amount of his body that was submerged 李普尼基说，他的研究结果也有历史证据可以支持，像是先前提到的希腊数学家阿基米得，就是躺在澡盆里的时候才想清楚，从他的澡盆里溢出的水量，和他泡在水下的身体体积成正比。
The thesis mainly investigated the bati _ 4o _ 9 ( bt _ 4 ) , which has the lowest dielectric loss in ba - ti system , and ( ba , sr ) tio _ 3 , the a position substitute compound of batio _ 3 . the dielectric properties of bt _ 4 / bst with different preparation way and different elements doping were investigated . a archimedes method , xrd , sem , impedance analyzer , network analyzer and hakki - coleman method were used to investigate the density , phase formation , microstructure , dielectric properties and doping mechanisms 本论文以在ba - ti系中具有最低介电损耗的bati _ 4o _ 9 ( bt _ 4 )高频介质陶瓷和batio _ 3a位sr取代而得的( ba , sr ) tio _ 3 ( bst )高频介质陶瓷作为研究对象,对不同粉体制备方法制备的bt _ 4 / bst高频电介质材料进行不同元素的掺杂,运用阿基米德方法, x射线衍射分析仪,扫描电子显微镜和阻抗分析仪,网络分析仪, hakki - coleman法等方法手段和测试仪器测试烧成样品的密度,相组成情况,微观结构和介电性能,探讨造成介电性能起伏的形成机理。
