Surface tension holds water droplets together and would make them spherical in the absence of other forces such as gravity, because a sphere has the smallest surface to volume ratio. Many animals take advantage of surface tension on ponds. Common insects called water striders, or pond skaters, ...
The feathers of aquatic birds must therefore be highly water repellent to prevent the displacement of the air layer. This study investigated the effects of hydrostatic pressure, which is related to body mass and behaviour, and water surface tension on the wettability of adult contour feathers of ...
Clotting is efficient because of the high value ofsurface tensionof water. 由于水的表面张力很高,血液得以凝固. 期刊摘选 Surface tensionis one of the important control parameters of the ceramic squeegee oil. 表面张力的控制是陶瓷印油产品的主要控制指标之一. ...

The contact angle formulation on the ideal homogeneous and smooth surface was derived by the Young's equation13, which relates the intrinsic contact angle to the surface tension between the three phases. $${ \gamma_{sv}}{ - }{\gamma_{sl}} = {\gamma_{lv}}\cos \theta .$$ (1) Con...
