Summary

THE VARIATIONS IN THE CONDENSATION STATES MEASURED SIMULTANEOUSLY BY HIGH SPEED AND VIDEO CAMERAS ARE SHOWN FOR BOTH TRANSITION MODES. THE CONTACT ANGLES OF SUBSTANCES DURING CONDENSATION WERE COMPARED. THE VARIATIONS IN THE CONDENSING STATES WERE GENERALIZED AND TABULATED. THE MECHANISMS OF THE TRANSITION WERE DISCUSSED. THE CONTACT ANGLE AND THE VISCOSITY OF THE CONDENSATE WERE THE CONTROLLING FACTORS IN THE CASE OF CONTINUOUS MODE TRANSITION, AND THE CURVE SHAPE OF THE JUMPING MODE WAS SIMILAR TO THE CONTINUOUS ONE, EXCEPT FORAN UNCONNECTED PART BETWEEN THE JUMPING AND FILM POINTS.
