应用正交曲线坐标系下的二维水深平均数学模型对大型泵站的引水河道流场进行了数值模拟。
The 2_d average water depth mathematical model in orthogonal curvilinear coordinate system is used for the numerical simulation of the flow field in the diversion channel of large pumping station.
即使这样,水位还是下降了很多:在瓦拉纳西,恒河曾经平均水深197英尺(60米),但是有些河段现在只有33英寸(10米)。
Even so, water levels have fallen steeply: the Ganges once had an average depth of about 197 ft. (60 m) around Varanasi, but in some places it is now only 33 ft. (10 m).
港区水深大,平均水深为12.2米,万吨级的远洋巨轮可以全天候进出港口。
Port depth, average water depth of 12.2 meters, ton ocean liners can be all-weather port.
It reminds me of a joke about the statistician who drowned in a pool with an average height of 10 inches.
这让我想起一个统计学笑话,在一个平均水深为10英寸的游泳池里,谁会被淹死。
You see you cannot tell the height or the depth rather of a pool based on the average.
只知道平均值,并不知道游泳池的水深。
