Having reviewed both domestic and international dissertations about resource pricing theories, compared domestic with foreign practices, stepped on the base of domestic realities, the author of this dissertation analyzes the pricing system of mineral resources both from theories and from its practices:First, analyzed China's current governmental pricing system and its effect on the market, and found some regulation problems such as inadequation and excession. Second, compared different mineral resources pricing methods and its effects on the market, and suggested new mineral resources pricing system for China. Third, raised some suggestion on how to regulate and manage through government administration in this new pricing system.

论文中借鉴国内外成熟的资源定价理论，对比国外通行做法，立足于国内实际，从理论和实践两方面对矿产资源的定价体系进行研究：一是分析了现行中国矿产资源政府行政定价的制度及其对市场的影响，找到部分调控影响不到、不力或过度的问题；二是比较了国内外现行不同的矿产资源定价体系及其对市场的影响，提出了适应我国经济社会发展的新矿产资源定价体系；三是科学地提出了我国在应对未来资源提价过程中如何合理发挥政府调控手段的建议。

Of development economics. The famed Indian scholar Sudisen remarked "Deng Xiaoping is the greatest contemporary economist of the development economics", and I reckoned that Deng propelled the development economics to one fully new stage from various aspects and left inerasable influence on the historyof development economics after my comparatively entire, systematical and deep research.

Hypercube has many advantages, such as smaller diameter, simple routing algorithm, many parallel paths between any two nodes, and fault-tolerance, on the other hand that the Hypercube nodal degree increased logarithmetically to the number of nodes has limited network population. So we propose a constant nodal degree hierarchical topology to remedy the weakness of Hypercube and take advantages of Hypercube most. Given the definition of FCCN we analyse the basic properties including nodal degree , number of links , extensibility and diameter (maximum network communication delay). Also we proposed a simple and self-routing algorithm applied in FCCN. Although the self-routing algorithm is not optimal, but at more than 82% case it can get the shortest path, and the percent is larger and larger increased with network levels. By the self-routing algorithm the internodal distance is calculated to evaluate the network communication delay more clearly. The average internal distance is in order of the cubic root of the network population that is almost same as logarithmetically relation in a few thousands. FCCN is a highly scalable network due to its recursive construction.

首先在比较了基本互连网络的基础上，看到超立体网络的杰出性能，包括网络直径小、寻路算法简单且为自寻路算法、容错能力好等等，但是由于其节点度随网络的规模的增加而按对数关系增长，使得超立体网络的应用规模受到极大限制，所以为了能最大限度利用超立体网络的优点的同时弥补其节点度方面的不足，作者提出了节点度等于常数4的FCCN网络结构，来最多地利用立方体网络的优点；然后在对FCCN网络进行严格的定义后，分析了网络的节点度、链路数、延伸特性、网络的直径（决定网络的最大通讯延迟）等，并提出了适于FCCN网络的简单的自寻路算法，计算自寻路算法可得到最短路径的比例，看到在多于82％以上的情况自寻路算法都是最优的，而且比例随网络层数的增加而增加；应用所提出的自寻路算法计算了可以更加准确反映网络通讯延迟的参数—网络平均节点距离，计算得到此参数与网络大小的立方根成正比，此比例关系在网络的规模在几千节点以内与对数关系的网络几乎一样；FCCN网络是一高度可扩展结构，这是因为FCCN的递归构成方式，使得网络在增加节点时其原有的拓扑结构可以保持不变，不需对网络进行重新设计，为网络的实用扩展提供了条件；理论分析得出FCCN网络是一种高度可扩展高性能网络的结论。

Chapter 8: We discuss the acceleration of multigrid by Krylov subspace approaches, and recognize the reason for slow convergence of algebraic multigrid methods is that error reduction is significantly less efficient for some very specific error components which may cause a few eigenvalues of the algebraic multigrid iteration matrix to be considerably closer to 1 than all the rest. However, the eigenvectors belonging to the few isolated eigenvalues can be expected to be typically captured after only a few conjugate gradient iterations, which accelerate algebraic multigrid algorithms. Theoretical analysis and numerical results of some practical problems show the iterant recombination accelerates algebraic multigrid convergence.
