The measured results of dropwise condensation curves for three organic vapors on a trilauryl trithiophosphite adsorbed copper surface were shown in the former report. Two different types of drop to film transition, continuous and discontinuous types, were observed. The variations in the condensation situations measured simultaneously by high speed and video cameras are shown for both transition types. Then, the contact angles of three substances during condensation are compared. The variations in the condensing situations in all cases measured are generalized and tabulated. Furthermore, the mechanisms of the transition are discussed. It is certified that the contact angle and the viscosity of the condensate are the controlling factors in the case of continuous type transition, and the shape of the discontinuous type curve is similar to the continuous type curve, except for a discontinuous part between the jumping and film points.
