Archimedes' this experiment is the embryo of "hydrostatics".

阿基米德的这个实验，就是"静水力学"的胚胎。

Archimedes did important work not only in geometry, but also in arithmetic, mechanics, and hydrostatics.

阿基米德是古希腊数学家、物理学家、天文学家。

The unit of hydrostatics takes the concept of buoyant force as its base, the Archimedes theory as its kernel, and the condition of sink or emerge as its representation.

"浮力"是流体静力学中应用性较强的基础知识之一，也是初中物理教学的重要内容。

The list starts with Archimedes and Kepler, whose three laws of planetary motion were not, incidentally, called "laws" by either him or Newton.

这些定律的名单起始于阿基米德和开普勒，后者的行星三大运动定律可不是被他自己或牛顿偶然地称为"定律"的。

In the paper, on the basis of aggregation of previous studies, the development of optical technology and development trends at home and abroad are introduced, the principle of Fresnel lens is summarized. In accordance with its principle, circle equidistant steps Fresnel lens design is described. And on this basis, based on Fresnel design, also based on a continuous upward spiral of the plane curve concept, incidence surface and the backlight is set up to greet Archimedes - Fresnel lens design formula and the Second parabolic type Fresnel lens design formula, and on this basis, the advantages and disadvantages of the three designs is discussed.

本文在充分了解非球面光学技术在国内外的发展状况和趋势的基础上，同时从菲涅尔透镜的光学原理出发，并根据它的工作原理推导了圆环等距菲涅尔透镜的设计步骤，并在此基础上依据菲涅尔的设计思想，同时依据平面曲线的连续又呈螺旋的构思，推导出了迎光面和背光面阿基米德型菲涅尔透镜的设计公式和二次抛物面型菲涅尔透镜的设计公式，并在此基础上讨论了这三种设计各自的优缺点。

However, logarithmic spiral can be used to substitute for the Archimedes curve to solve such problems and guarantee the stability of cutter machinability .

传统的阿基米德螺线齿背的铲齿成形铣刀在重磨前刀面后，切削刃上各点的后角将发生变化，从而影响刀具切削性能的稳定。

However, logarithmic spiral can be used to substitute for the Archimedes curve to solve such problems and guarantee the stability of cutter machinability.

若改用对数螺线作为铣刀铲背曲线，则克服了阿基米德螺线的不足。

He was drawing in this circle geometrical lines, and seemed as much absorbed in his problem as Archimedes was when the soldier of Marcellus slew him

他正在圆圈里划几何线，那神态就象阿基米德当马赛鲁斯的兵来杀他时的那样全神贯注。

He was draw in g in this circle geometrical l in es, and seemed as much absorbed in his problem as Archimedes was when the soldier of Marcellus slew him

他正在圆圈里划几何线，那神态就象阿基米德当马赛鲁斯的兵来杀他时的那样全神贯注。

At the same time,Archimedes gives an exact proof on the formula of area of circle,with the method of exhaustion method depending on the Cyclotomic.

刘徽之前，希腊的阿基米德用穷竭法也证明了圆的面积公式。其中，刘徽的证法强调计算的程序性和构造性，而阿基米德则倾向于演绎的严谨性。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
