gravity circulation

基本解釋

The liquid level must be high enough to assure the gravity circulation of liquid. In the jet pipe, the flowing gas holds a turbulent state.
要求液面高度能保證凈化液的自流，射流管內(nèi)氣體處于湍流狀態(tài)，混合氣流速度應(yīng)達(dá)到連續(xù)射流所需的臨界速度。
Westinghouse says the technology is safer because it uses a simpler design that relies on passive mechanisms such as gravity and the natural circulation of water to prevent accidents.
西屋電氣稱，這種技術(shù)更加安全，因為它采用了更加簡單的設(shè)計，利用重力和水的自然循環(huán)等被動機制預(yù)防事故。

The turbidite deposits are of both gravity flow and traction flow, forming not only fan-shaped lobes and dendritic channels, but also high tortuous channel systems by its inner circulation flow.
濁積水道的形態(tài)主要受地形坡度控制，其中高彎度水道主要發(fā)育在緩坡地段。
