针对典型形状微通道(微缝隙)在滑移边界条件下，利用粘性流体运动方程和动量方程，推导出速度场和流动阻力。
Aimed at typical shape micro-channel (fissure) under slip confine condition, it used dauby fluid motion equation and momentum equation, derived pace bout and running resistance.
舞者要阻止从空中掉落的惟一方法便是中止自己的动量，而这需要一个反面的来自一个平面的阻力。
The only way a dancer can stop dropping through the air is by stopping the body's momentum, which requires an opposing force-the ground.
他们选择什么样的阻力级别，这个我不关心；如果他们的运动量呈下降趋势，或者如果他们走向旁边与女友闲聊，我希望他们能够重新养成之前没有养成的好习惯。
I don't care what resistance level they're on, if they're on an incline, or if they're walking sideways talking to their girlfriend, I want them to pick up habits that they haven't before.
