不同的特性进行了讨论，如密度和压力。

Archimedes' Principle is the law of buoyancy.

阿基米德的原则是法律的浮力。

取胫骨上端骨标本，拍摄完整骨和松质骨块的X光片，做X光片的微机图象分析测量骨端平均相对矿物质密度和不同部位的相对矿物质密度。

Hydrostatics - Archimedes' Principle - Fluid Dynamics - What Makes Your Boat Float?

流体静力学-阿基米德原理-流体动力学-是什麼使你的船浮著？

"These flood gates are unique because they use stainless steel. According to wind speed and Archimedes' principle of buoyancy, they can rise quickly to the surface of the sea, making a barrier. It can even go up to three meters above sea level to keep out floods."

「这个水闸门的特色，是不锈钢做的，根据风速和阿基米德浮力原理，让它可以快速升降在海平面上形成一座堤防，甚至可以高达海平面三公尺的高度，来防止水患。

Theresistance to a rising object is one order magnitude greater than that to a settling object. The efficient buoy-ancy on a flaky object, which lies flat on the gas distributor, is much less than that calculated according tothe Archimedes' principle.

物体上浮时受到的阻力要比下落时大一个数量级，平躺在气体分布板上的扁平状物体受到的浮力比理论计算值小得多。

The floating gates, which have a hollow cavity inside, work according to Archimedes' principle of buoyancy. When compressed air is pumped in, emptying the gates of water, the buoyancy of the giant panels will be greater than their weight, and in just 30 minutes the barrier will float above the surface. The gates are attached to the seabed with hinges, which are designed to absorb the force of waves and keep the barrier in place. The gates will only be raised when waves are higher than 1.1 meters, to reduce interruption of the sea currents to a minimum.

这些中空的水闸门，主要依照阿基米德浮力原理操作，当闸门内注入高压空气排水后，闸门受到的浮力大於闸门重量，只要三十分钟就能浮出水面，闸门底部则用轴承固定在海底，再透过细部结构设计能够悉受波动力量，保持闸门的稳定性，而水闸门只有在浪高超过110公分的时候才会升起，把对海水交换的干扰降到最低，其他维护潟湖生态的措施也获得欧盟肯定，所以在2009年4月，取消摩西工程违反自然保育法的决议。

Its concept in measuring body fat is based on Archimedes Principle .

它在测量身体脂肪的概念是基于阿基米德原则。

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。

The density of potassium fluotantalate and its mixed melt salt system with sodium chloride, potassium chloride, sodium fluoride and potassium fluoride are measured by Archimedes principle .
