浮力

Consider neutral buoyancy your most valuable technique.

把中性浮力看作你最宝贵的技巧。

In the fan delta plain, the sediments, with relatively large grain sizes, jump forward with the thrust of water flow, while, in the front slope, the sediments have relatively small grain sizes, weltering and depositing a-long the slope under the force of gravity, forming typical normal grain size gradation.

扇三角洲平原以水流推力作用为主，沉积物以滚动、跳跃方式搬运，粒度最粗；前缘斜坡以重力作用为主，沉积物顺坡向下滚动、沉积，粒度略细，且具有明显的正粒序特徵；前扇三角洲以浮力作用为主，沉积物为悬移质沉降，粒度最细。

The lever-ball float type trap employs the buoyancy and leverage principles: to make the ball float ascend or descend by the change in the liquid level and then the ball float drives the lever to make the valve disc depart from or touch the valve seat to realize drainage and close the block vapor.

Moderate buoyancy could be used as favorable load, while an excessive depth of underground water table will cause hazard.

适度的地下水浮力可以作为有利荷载加以利用，而过量则会形成危害。

For flying birds that also dive, such as Auks, this low density skeleton means that birds must work hard to overcome considerable natural buoyancy when diving below the water surface.

而对于那些也需要潜水的鸟类来说，如海雀，那种低重力就意味着它们在潜到水下时，必须承受相当大的浮力。

The surface tension of silicone oil can be reduced to 12 to 14 ergs/cm2 by the absorption of lipoprotein.

我在沙发上说的硅油有钝性分离作用，不仅仅是表面张力，或者浮力的作用。

Among it wrap up surface auxiliary that cover,-COOH,-OH, sulphur base S032~ sour hydroxyl carboxyl , etc. group last the not facilitating last aluminium the buoyancy of floatings of the powders, and C-C chain , alkyl phenyl R-C6HU fatty alcohol base fatty acid base R-COO, R-0- long in structure, etc. base group kiss not oily, base these group add , facilitate aluminium powder water build rise of area.
