最近，我们在连续相场晶体(PFC)方法的框架内导出了任意泊松比的各向同性和各向异性晶格系统的一般模型[R.Prieler，J.Hubert，D.Li，B.Verleye，R.Haberkern，H.Emmerich，J.Phys.：Condens]。Matter 21(2009)p.464110]，并展示了它的参数如何从经典的密度泛函理论中得到[M.A.Choudhary，D.Li，H.Emmerich和H.Löwen，J.Phys.：Condon]。Matter 23(2011)第265005页]。在这里，我们提出了一种模拟任意泊松比各向异性材料系统的一般方法。这样，我们可以第一次识别任意泊松比的PFC解，从而将PFC方法的适用性扩展到更大类的材料系统。
Recently, we derived a generalized model for isotropic as well as anisotropic crystal lattice systems of arbitrary Poisson's ratio within the framework of the continuum phase-field crystal (PFC) approach [R. Prieler, J. Hubert, D. Li, B. Verleye, R. Haberkern, H. Emmerich, J. Phys.: Condens. Matter 21 (2009) p.464110] and showed how its parameters can be derived from classical density functional theory [M.A. Choudhary, D. Li, H. Emmerich and H. Löwen, J. Phys.: Condens. Matter 23 (2011) p.265005]. Here, we present a general procedure to model anisotropic material systems of arbitrary Poisson's ratios. In that way we can for the first time identify PFC solutions of arbitrary Poisson's ratios and thereby extend the applicability of the PFC method to a larger class of material systems.
