1、For the hot water storage tank to the water temperature stratification, such as the top of the hot water storage tank water use, should reduce the nozzle velocity.───对于需要水箱水温分层的储热水箱，如顶水使用的储热水箱，应降低管口流速。
2、physical differences between regions, such as currents and the stratification of the water column, will also complicate the response of food webs.───不同的地区，水的物理性质(如：水体的流动与分层)也会有所差异，这也将使得鱼类对食物网的反应复杂化。
3、Accurately deriving the true liquid flow velocity is the key for determining the stratification flow rate of oil and water and logging interpretation of liquid producing profile.───准确求取流体的真实流动速度是确定油水各相分层流量及产液剖面测井解释的关键。
