论文摘要
在本文中，根据模型Schrödinger方程，我们考虑了液态氦气中空化的隧道机理，并获得负压的阈值作为3HE和4HE的温度的函数。提出了在Lenard-Jones相互作用电位的近似中获得的平坦和弯曲界面的表面张力系数的结果。结果表明，在自然界中，空化开始的临界压力的温度依赖性是逐步的。获得的临界压力值与实验数据达成满意的一致性。
In this paper, on the basis of the model Schrödinger equation, we consider the tunneling mechanism of cavitation in liquid helium and obtain threshold values of negative pressure as a function of temperature for 3He and 4He. The results of calculating the surface tension coefficients for flat and curved interfaces, obtained in the approximation of the Lenard-Jones interaction potential, are presented. It is shown that the temperature dependence of the critical pressure at which cavitation begins is stepwise in nature. The obtained critical pressure values are in satisfactory agreement with the experimental data.
