On the basis of the datum in the expe riment,it studied the transverse and longitudinal mode due to liquid conformation instability, analyzed the vibration characteristic of two-phase flow in the well. It also set ground to the next simulation. This paper shows the importance of research on two-phase flow in the well-washing craft of gas jet.   Key words: Well-washing machine;Two-phase flow;Mechanism;Vibration
