它就像一道从天而降的瀑布，猛烈地阻隔河流中正常连续流动的水流。

It is the waterfall that interrupts violently the peaceful continuous flow of the river's water.

连续测量的水流速度是通过不同源距探测器计数率的比值来确定。

Water-flow velocity of continuous measurement was determined by the ratio of count rate value of different source spacing detectors.

在一个连续不断的水流中，比如在河水中，你得逆流瞄准你的目标：你的力气有些是花费在向着终点，有些力气是花费在对抗水流的。

With a continuous current, like in a river, you have to aim upstream of your target. Some of your effort will go into getting you closer to the finish and some will go into fighting the current.
