在本文中，我们提出了先前提出的超流体 4He 随机模型的一些流体动力学结果。我们特别讨论了随时间演化的可能性，这种演化从旋转初始状态开始，导致涡量集中在奇异区域的渐近稳态解。这种渐近平稳解的一个例子是量化涡线解。我们还回顾了量子临界滑移速度的概念，并研究了自旋问题和涡线系统创建的一些可能后果。
In this paper we present some hydrodynamical consequences of a previously proposed stochastic model for superfluid4He. We discuss in particular the possibility of time-dependent evolutions which, starting from a rotational initial state, lead to asymptotic stationary solutions where the vorticity is concentrated in singular regions. An example of such asymptotic stationary solutions is the quantized vortex line solution. We also recall the concept of quantum critical slipping velocity and investigate some possible consequences on the spin-up problem and on the creation of systems of vortex lines.
