求翻译：When the threshing drum rotates the rasp bars and the coverings cause an air-flow. To avoid grain being blown onto the straw walkers this air-flow should be less than the terminal velocity of the grain. The tests showed that roughly 10% of threshed grains had a terminal velocity less than是什么意思？ 待解决
