摘要

摘要: 本文对演化方程进行了讨论,从而能够唯象地描述微观结构行为,如Maxwell气体的部分可逆流动、恢复性、结构松弛以及从光散射和分子动力学得到的其它实验结果。讨论所得结果涉及Zaremba补充式(ansatz)的重新评价,可用来解决输运方程中具有显着非线性的问题。

Abstract: In the paper the evolution equations are discussed so as to enable a phenomenological description of microstruchtral behaviour e.g. partially reversible flow of Maxwellian gas, recovery structural relaxation and other experimental results coming from light scattering and molecular dynamics.The result deals with the revaluation of Zaremba's ansatz.It leads to resolution of problems with substantial and available nonlinearities in the transport equation.
