然后采用IFFT算法和自适应数值积分算法计算二维积分，得到了低音速、跨音速和超音速移动荷载作用下动力响应的数值结果。
Coupled IFFT algorithm and adaptive quadrature algorithm was employed to compute double integrals in the analytical solutions. All the subsonic, transonic and supersonic cases were computed.
如果飞得太快的话，升力的中心会向机翼后部移动，使飞机的机头朝下，导致飞行速度增加，直到飞机接近音速。
If you go much faster, the center of lift moves back on the wing, pushing the nose down and increasing velocity, until you soon approach the speed of sound.
