The main contributions of this dissertation are In chapter 2, we propose a scientific visualization system modal which is based on large-format display technology and Client-Commware-Server structure. In chapter 3 and chapter 4, we accomplish two large-scale scientific visualization systems. In chapter 5 and chapter 6, we propose HFFT on hexagon and parallel dodecahedron domains, and reduce the computational complexity from O and O to O and O . Lastly, we propose a parallel HFFT on distributed memory computers.

本文的主要贡献如下：提出了使用大屏幕显示技术、适用于大规模科学计算可视化系统的Client-Commware-Server模型；实现了油藏数值模拟和分子模拟两个大规模科学计算的可视化系统；给出了二维三方向六边形区域、三维四方向十二面体区域上的HFFT算法，将变换的计算复杂度分别从直接计算的O和O量级降到了快速算法的O和O量级；最后，本文给出了一种基于分布式存储的并行HFFT算法，并对影响、提高并行算法的若干因素进行了分析。

Peptide nucleic acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked. PNA is uncharged, highly stable in chemical and biological environments, and binds complementary DNA and RNA targets with remarkably high affirnity and specificity.
