The accuracy and efficiency of finite element numerical analysis have close relationship with the mesh quality and density distribution. In order to ensure the hexahedral mesh transition gradually and conformably, a set of 8-refinement based density control templates is proposed newly. The corresponding date structure and template application techniques are also given.

This reflects that the continent is the piece-togrther block of many blocks and the continent was conserved, and evolved and suffered many times tectonic reworking, which made the integrated strength of the lithosphere with apparently differentness and variation in different tectonic units and different location of the same unit.

这也充分反映大陆是多块体的拼合体，长期被保存、演化，遭受多次构造变动使之总体岩石圈综合强度随不同的构造单元与同一单元不同构造部位具有明显的差异和多变，从而也反映了大陆形成、演化成因和结构与组成的特殊性与复杂性，区别于大洋岩石圈。

Origin, developmental changes and homologies of the stage morphostructures were considered according to their location in three morphogenetic fields. The first, or central, field forms at the prodissoconch I stage. It can be inherited by prodissoconch II and nepioconch stages in one taxa, or PD-II, N and dissoconch stages in others. The second, or postero-dorsal, field appears at the N stage, and the third field, or antero-dorsal, at the D stage.

主要对3个形态发生区域的阶段形态结构的起源、发育变化和同源性做了研究，其一，即中央区域，开始形成于前双壳I期，在某个分类单元它可以在前双壳II期和幼贝期形成，而在其它分类单元则在前双壳II期、幼贝期和双壳期形成；第二区域，即背部后区，在幼贝期出现；第三区域，即背部前区，出现于双壳期。

However it allows edges or elements to straddle between subdomains. In order to be used in conjunction with element-based Godunov algorithm, the RSB algorithm partitions the dual graph of the computational meshes, e.g.

为了将递归谱对分法与以单元为主的Godunov方法结合使用，本文将该方法用于Delaunay非结构网格的对偶图Voronoi图，然后再根据Voronoi图中的结点与Delaunay网格中的三角形单元之间的一一对应关系，得到Delaunay网格的分区。
