The key factors causing soil dried layers are great thickness and depth of membrane water zone under ground as well as small thickness of gravity water zone.

由降水少量决定的、埋藏深度小而厚度大的薄膜水带的存在是引起土壤干层发育的直接作用的因素。

Some areas in China are abundant in resources, but short of water source nearby, so the pressured gravity water transportation in long distance must be adopted.

我国一些地区资源丰富，但就近水源缺乏，不得不采用长距离有压重力输水。

The stepped low-pressurized water diversion system is a new type of gravity water supply system, which is simple in structure and water conservation weir is the pivotal structure.

分段低压输水系统是一种结构相对简单，采用分段降低水头的新型自流有压引水结构，而保水堰则是分段低压输水系统的关键建筑物。

And the idea was that gravity did work on the water and falling, and that work led to the generation of heat.

焦耳的想法是,重力对水，做了功。

New Orleans lies between the lake's water and the Earth's center where gravity wants that water to go.

NPR: Defying Gravity, and Odds, in New Orleans

Hydro dams can be reversed and pump water uphill so that the next day, when gravity pulls the water back down, the turbines spin to make electricity.

FORBES: A123 Bites the Dust Because They Forgot Their ABCs

It uses so-called passive systems for cooling, such as the gravity flow of water and natural circulation based on thermodynamics.
