我们给出了一类非理想多元格子Boltzmann模型的压强张量的理论，从而推广了X.Singh[Phys.Rev.E 77,066702(2008年)]适用于单组分流体。我们得到了直接作用在晶格上的压力张量的正确形式，所得到的平衡性质与数值模拟测量的结果非常吻合。并将结果与其他理论的结果进行了比较。
We present a theory to obtain the pressure tensor for a class of nonideal multicomponent lattice Boltzmann models, thus extending the theory presented by X. Shan [Phys. Rev. E 77, 066702 (2008)] for single-component fluids. We obtain the correct form of the pressure tensor directly on the lattice and the resulting equilibrium properties are shown to agree very well with those measured from numerical simulations. Results are compared with those of alternative theories.
