此外,静电力对沙粒运动轨迹的影响要明显大于空气升力,Magnus力的影响主要由沙粒角速度决定,当角速度很小时,其影响可以忽略,当角速度很大时,其影响非常显著。
The influence of Magnus force is determined by the angular speed of particle , therefore when the angular speed is small , the influence can be neglected .

足部的缺失以及双翼的角度不禁让人对这种设计的空气动力升力产生猜测。
The lack of legs , and the angle of the wings has lent to speculation about the design 's capability of aerodynamic lift .
