地震波场数值模拟是研究复杂地区地震资料采集处理和解释的有效辅助手段,地震波场数值模拟的主要方法包括两大类,即几何射线法和波动方程法。有限差分法是波动方程法中非常重要的一种方法,它的主要优点是占用内存小,计算速度快。论文采用高阶交错网格差分技术对一阶速度-应力弹性波方程进行数值求解,并对差分方程稳定性条件、频散问题以及边界条件处理进行了讨论。(Numerical simulation of seismic wave is a effective auxiliary means for studying seismic data acquisition, processing and interpretation. The main methods of seismic wave numerical simulation include two major categories, namely, the geometric ray method and the wave equation. Finite difference method, which main advantages are the small memory and computing speed, is one of the very important way for wave equation simulation. Paper uses the high order staggered-grid difference method for numerical calculation of the first order elastic wave equation with velocity and stress. And the stability condition of difference equation, dispersion problems, as well as boundary condition are discussed. )
《柔性字符串匹配》的英文版,是目前讲解字符串匹配算法的参考资料中比较全面和前沿的,很有参考价值和收藏价值(" Soft string matching" in English, is the string-matching algorithm on the reference in a more comprehensive and cutting-edge, a good reference value and value to the collection)
数据的逻辑结构、存储结构及它们之间的关系和相应的基本操作运算的定义和实现。 本书围绕数据结构的三种基本结构:线性结构(第2-5章)、树形结构(第6章)和图形结构(第7章)展开讨论,研究解决如下问题:一个具体问题的逻辑数据结构是什么?适宜选用什么样的存储结构?采用什么样的操作实现算法效率更高? (Logical structure of data storage structure and the relationship between them and the corresponding basic operation and the realization of the definition of computing. The book data structure around three basic structure: a linear structure (the first chapter 2-5), tree-like structure (Chapter 6) and graphics structure (Chapter 7) initiate discussions to resolve the following issues: a specific problem What is the logic of the data structure? Suitable choice of what kind of storage structure? What kind of operation to achieve more efficient algorithm?)
