【摘要】 本文建立了一种条件,在这种条件下,隐式的Oldroyd本构方程是等价于微分型本构方程。并且解释了这些条件的物理意义。最后给出了Maxwell型及Oldroyd型本构方程显式化的微分算符形式。更多还原

【Abstract】 We have established the conditions under which the implicit Oldroyd type constitutive equation is equivalant to a differential type constitutive equation. Physical interpretations of these conditions are given. Finally some explieit form for Maxwell type and Oldroyd type constitutive equations are given as illustrations.更多还原
