回答: 船的螺旋桨(especially a submarine)为什么不可以和飞机那样装在前面? 由 HunHunSheng 于 2006-5-30, 10:03:30:

why the 船的螺旋桨 is spinning clockwise, but not counter clockwise instead? Of course under the current design, the counter clock spinning would push the ship backward, but not forward. But why is it not designed to push forward with counterclock pinning and backward with clockwise spinning?

Is it more HunHun-stylish? :))
