- 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. 噪声总声级的变化较为复杂，由泡空化状态转换到片空化状态，空化数虽然减小，但总声级会突然降低。
- This paper studies measures for depressing valve lip cavitation,Compares virtue and short coming of Version improvement measures,bas ed on increasing Working Cavitation number. 笔者从提高空化数的角度出发，研究了减免阀门底缘空化的措施，并比较了各种改善措施的优劣.
- There are the optimal geometric parameters and operating conditions in the system and the degradation rate of rhodamine B increases with decreasing the value of the modified cavitation number. 试验结果表明:水力空化对若丹明B确实有降解作用,处理系统中存在最佳的孔板几何参数和操作运行条件,并且若丹明B的降解速率随修正空化数的减少而增大。
- With the decreasing of cavitation numbers, the vorticity value lowers since there is in large grad of the velocity in the cavitation area. 随着空化数的降低，空化区域的流场混合得更为均匀，从而使涡量的峰值逐渐减小；
