论文摘要
作为流体的物理特性,粘度反映了对汉密尔顿方程描述的混沌微观运动的平均效果。举例来说,提出,不可压缩的流体的固定状态可以通过几个合奏来描述,并以平衡统计力学的严格类比来描述。
Viscosity, as a physical property of fluids, reflects an average effect over a chaotic microscopic motion described by Hamiltonian equations. It is proposed, as an example, that stationary states of an incompressible fluid subject to a constant force, can be described via several ensembles, in strict analogy with equilibrium Statistcal Mechanics.
