常見例句雙語例句There is zero leading-edge suction, and the lift and induced drag are simply .平板機(jī)翼沒有前緣吸力,并且升力和誘導(dǎo)阻力都比較簡單。The cause of the reduction of lift lies in that, the losses of suction at upper surface are more than the increases of pressure at lower surface.升力系數(shù)的減小主要是由于地面效應(yīng)引起流場改變,下翼面壓力的增加量小于上翼面吸力的減小量引起;www.jasp.com.cnThus, in the worst case of zero leading-edge suction, the drag-due-to-lift factor K is simply the inverse of the slope of the life curve (in radians), as previously determined.因此,零前緣吸力的最壞情況是:由升力引起的阻力系數(shù)K是前面確定的升力曲線斜率的倒數(shù)(弧度制)。 返回 suction lift
