A、pressure does not fluctuate rapidly B、pressure remains steady and unchanged C、brine density does not exceed 1~5 D、brine density is too low
A、Gravity siphon effect B、Higher vacuum in the second-stage C、Difference in brine density between first and second stages D、lower pressure in first-stage
A、in an area of high density the water's surface is lower than in an area of low density B、surface water flows from an area of high density to one of low density C、the lesser the density gradient the freer the water is to move D、it is the density differences that cause the currents to stay in the troughs
