In this paper the conflicting discussion of scholastic view-point on seepage force which has lasted many years is stated. Then the physical concept of seepage force and its related forces including the resolved two components (a seepage force and a buoyant force) from seepage resultant force, the transformation between the seepage force and boundary pore water pressures, schematic diagram of forces acting on unit soil mass and the mathematic proof by Green theorem are described.

追述了多年來對滲透力學(xué)術(shù)觀點的爭論又黄又粗又长又硬又爽的视频，并再就此問題論述了滲透力的物理概念及其與之相關(guān)的各力（包括滲流作用合力及其分解成的兩個分力，滲透力與周邊孔隙水壓力的轉(zhuǎn)換關(guān)系及各力作用在單位土體的圖示www.13色哟哟；從數(shù)學(xué)上引用格林公式日韩高清自拍区视频在线观看，證明土體表面水壓力與土體本身滲透力之間的轉(zhuǎn)換關(guān)系。

Based on the theory of hydromechanics, this paper has proved that the resultant force of seepage force and buoyant force is identical to that of ambient pore water pressure.

文中以流體力學(xué)的基本理論為依據(jù)天天夜夜操2021，從滲透力概念定義的微觀源頭上欧美老妇乱子BBBBBBBW，證明了滲透力是一種等效力。

Buoyant force is not only the base of hydrostatics which has many applications, but also the key point of physics teaching in the middle school.

"浮力"是流體靜力學(xué)中應(yīng)用性較強(qiáng)的基礎(chǔ)知識之一啊嗯网站，也是初中物理教學(xué)的重要內(nèi)容在线视频亚洲。

buoyant force：浮力

其次,我們使用比較抽象的浮力(buoyant force)概念來敘述阿基米德原理:實證主義(positivism)早期的社會科學(xué)家,為了和形上學(xué)劃清界線,往往刻意避免使用較抽象的概念.

buoyant force：上壓力

bunk spike [車輛]轉(zhuǎn)面梁上的鐵齒 | buoyant force 上壓力 | burls figure 瘤狀花紋
