在10,000 ~ 90,000的高雷诺数范围内，测量了流动摩擦系数、局部和平均对流换热系数。
In high Reynolds number range of 10,000 ~ 90,000, the flow friction factor, local and average convection heat transfer coefficients were determined.
风向在城市里也会改变，因为建筑物增加了它们周围流动的空气的摩擦力。
Wind movements are also modified in cities because buildings increase the friction on air flowing around them.
“几十年前，冰川坐落在这道海脊上，其摩擦力阻止了冰川流动，”他解释道。
"Some decades ago, the glacier was sitting on this ridge and the friction of the ridge was restraining the flow of the glacier," he explained.
