If the surface is cooled and the air above it warmed, there is less tendency for air from near the surface to rise; reduced convection will tend to lead to fewer clouds and reduced rainfall.

假设地表降温而其上的空气升温，那么地表的空气要向上升腾就变得不那么容易；而对流减少导致的将会是趋向于减少的云层生成和降雨。

The efficiency of this process depends on the surface area of the sorbent, and an easy way to increase the surface area is to spray a liquid sorbent into the air as a fine mist.

这一过程的效率取决于吸收材料的表面积，我们可以通过将液态的吸收剂以细水雾的形式喷入空气中，就能轻松的扩大接触面积。

It has a long way to go to operate an air wing, provide air, surface, and sub-surface defenses for the carrier, supplying the carrier, and training the personnel to operate it. That is many years off.

形成空中作战联队，为航母提供空中，表面，次表面的防御，航母供给以及人员培训和操作等方面都还有很长的路要走。

These include: eight sophisticated diesel submarines, advanced SU-30 fighter aircraft, modern air-to-air and air-to-surface weapons, supersonic anti-ship cruise missiles and as many as 350 short- and medium-range ballistic missiles.
