Cahn Hilliard equation

The author studies an explicit fully discrete spectral method and pseudo spectral method with weaker stability condition for the Cahn Hilliard equation.

设Ｇ是ｐ阶自补图，文中讨论了含悬挂顶点的ｐ＋４阶自补图与所有ｐ阶自补图的关系，给出了由ｐ阶自补图构造出ｐ＋４阶含悬挂顶点的自补图的方法及含悬挂点的ｐ＋４阶自补图的数目Ｎ１（ｐ＋４）。

Of all trees on given order n,diameter d and pendant vertices number s, which achieves the maximal spectral radius? Let Tn,d,s be a tree with order n,diameter d and pendant vertex number s obtained by spanning s-2 paths of almost equal lengths at r th-vertex of fixed path Pd+1,where r=r(d) is the integer part on(d+1)/2.

研究了在阶为n、直径为d且悬挂点数为s的所有树中,树具有最大的谱半径问题。

The numbers of physical cover of the cover system in NMM when the crack was extended were amended through the setting of hanging nodes.

探讨了基于三角形有限元网格的平面流形元覆盖系统;通过设置流形单元的悬挂节点来修改裂纹扩展时流形覆盖系统中的节点下标(物理覆盖编码),通过初始有限单元被物理网格再剖分后所生成的流形单元链表的设置提出了裂纹扩展时新生成的流形单元中物理覆盖编码(有限单元节点及下标)、悬挂节点信息和积分区域角点信息的生成方法,进而提出了裂纹扩展时流形元方法的物理覆盖和流形单元的生成算法。

In this thesis we investigate some graphic transformations and properties of extremal graphs on the Randic index among all trees with k pendant vertices, and use some of these transformations to study the problem of extremal values of the Randic index.
