1、drag coefficient of the aft wetted area of vehicle also decreased with the ventilated cavitation number.───通气空化数的减小，超空泡航行体尾部沾湿区域阻力系数也逐渐减小。
2、ventilated cavitation number decreased with the ventilation flow rate by exponential law at constant velocity.───在流速恒定情况下，随通气率的增大，通气空化数逐渐减小，呈指数规律衰减。
3、paraboloid cavitation pattern is an isolated type; and the initial cavitation number is 0. 2 or so.───渥奇段的空化为体型分离型，初生空化数约为0．2左右。
1、Some factors of effect i. e. cavitation number and inlet pressure are discussed and the decompositional regular is proposed.
2、The drag coefficient of the aft wetted area of vehicle also decreased with the ventilated cavitation number.
3、The ventilated cavitation number decreased with the ventilation flow rate by exponential law at constant velocity.
4、The unsteady supercavity shape and length is calculated by using the finite difference time discretization when cavitation number changes.
5、The total noise changes complexly. When the bubble cavitation turns on the sheet cavitation, the total noise will reduce suddenly although the cavitation number becomes smaller.
