论文摘要
已经重新研究了七十年的流体和血浆放松问题。已经提出了一种消失的非线性转移的新原理，以发展中性流体和等离子体的湍流的统一理论。与以前的研究不同，新原则使我们能够在不经过任何变化原则的情况下明确地找到放松的状态。发现本文获得的一般松弛状态可自然支持与几个数值研究一致的压力梯度。放松的状态将减小为贝尔特拉米型对齐状态，在压力梯度忽略不足的情况下。
A seventy year old problem of fluid and plasma relaxation has been revisited. A new principle of vanishing nonlinear transfer has been proposed to develop a unified theory of turbulent relaxation of neutral fluids and plasmas. Unlike previous studies, the new principle enables us to find the relaxed states unambiguously without going through any variational principle. The general relaxed states obtained herein are found to support naturally a pressure gradient which is consistent with several numerical studies. Relaxed states are reduced to Beltrami type aligned states where the pressure gradient is negligibly small.
