The trajectories of particle movements in a standing wave acoustic field are recorded by fast-speed video camera. 采用可视化实验的方法,拍摄可吸入颗粒在驻波声场中的运动轨迹。
VSWR.Abbreviation for Voltage Standing Wave Ratio. VSWR电压驻波比的缩写。
VSWR? Voltage Standing Wave Ratio? 电压驻波比?
By measuring the acoustic pressure at two points along the tube, the standing wave sound field in the resonator could be separated into incident and reflected components. 在该方法中，只要测量沿程两点的声压，便可将管内平面驻波声场分解为入射波和反射波两种分量。
