摘要: The invention relates to a method for determining deformation delay time constant of polymer solutions. mainly comprises the following steps: recording moving image liquid drop vibration by using an ultrasonic droplet suspended instrument and high-speed camera; carrying out interface identifying fitting on obtained image; taking as horizontal axis instantaneous amplitude vertical axis, so obtain curve along with change. each solution can be determined, is effective feasible, accurate in numerical value. Thus, parameters are provided experiments mathematic models related solution.
