Experiments were conducted at temperatures of 260, 266, 270, and 276 K and at nitrogen concentrations in the solution of 0.5 and 1.5 mol%. Pressure decrease rates were taken in the range 0.01–0.1 MPa/s. Distribution functions of liquid boiling-up events in dependence on pressure have been obtained allowing one to determine the most probable (attainable) pressures of liquid boiling-up and the nucleation rate. The results are interpreted in terms of nucleation thermodynamics and kinetics in liquids on a solid surface containing inclusions that initiate the boiling-up processes. It is shown that for realizing homogeneous nucleation it is not necessarily required that the wettability is close to the ideal one. The reasons for the discrepancy between experimental data and predictions of homogeneous nucleation theory at nucleation rates J 3 × 106 s−1 m−3 are discussed. Доп.точки доступа: Pankov, A.
