最近的地幔对流数值研究包括了板块构造的各种特征。本文介绍了三种方法建模板：通过材料特性，通过力平衡，并通过薄幂律片近似。所获得的结果进行了比较，使用每种方法的一系列简单的计算。从这些结果中，不同的参数化之间的标度关系的开发。虽然每种方法在表面板内产生不同程度的变形，但表面热通量和平均板速度在百分之几内一致。主要结果不依赖于板建模方法，因此代表了所建模的物理系统。
Recent numerical studies of convection in the earth's mantle have included various features of plate tectonics. This paper describes three methods of modeling plates: through material properties, through force balance, and through a thin power-law sheet approximation. The results obtained are compared using each method on a series of simple calculations. From these results, scaling relations between the different parameterizations are developed. While each method produces different degrees of deformation within the surface plate, the surface heat flux and average plate velocity agree to within a few percent. The main results are not dependent upon the plate modeling method and herefore are representative of the physical system modeled.
