Description: FORTRAN是一门在数值计算领域有着重要用途的高级计算机语言。本书深入浅出、循序渐进地向读者讲述如何使用FORTRAN进行程序开发。本书内容包括FORTRAN起源及发展、FORTRAN语法基础、简单输入与输出、常量和变量、种别和属性、常用内部过程、运算符及表达式、程序流程控制、FORTRAN中的数组、FORTRAN程序单元、高级输出与输入、文件操作、FORTRAN指针等内容。基本上涵盖了FORTRAN语言的方方面面。为便于读者进一步加深对FORTRAN语言的理解和应用，本书最后几章专门列举了一些FORTRAN的应用实例，具体讲解了常用数值算法、文件处理、搜索与排序等内容。-FORTRAN is a numerical calculation in the field of use has an important high-level computer language. This book in layman s language, the reader step-by-step how to use FORTRAN to program development. FORTRAN book covers the origin and development, FORTRAN syntax based on a simple input and output, constants and variables, and attributes of other species, commonly used within the process operator and expression, the program flow control, FORTRAN array of, FORTRAN program units, High output and input, file operations, FORTRAN pointer and so on. Essentially covers all aspects of the FORTRAN language. For the convenience of the reader to further deepen the understanding of the FORTRAN language and application of the final chapters of the book lists a number of specialized application of FORTRAN, the specific numerical algorithm on a common document processing, content search and ranking.

Description: 用相位移加实现速度纵横向变化、复杂陡倾地质模型的正流模拟，为复杂波场的地震、地质解释提供了精确、实用的方法。一般情况下，相位移延拓方法对徒倾斜地层成像精度高、稳定性好、计算快，但实现速度的横向变化困难；而频率、空间域的有限差分法算法简单、稳定性好、能适应速度的纵横向任意变化，但偏移陡断地层存在很多问题-Using phase shift and realization of vertical velocity variations, complex flow simulation of steep dip geological model, seismic and geological interpretation of complex wave field provides accurate and practical way. Under normal circumstances, phase displacement extrapolation method for imaging of tilted strata of high precision, stability, quick calculation, but difficulties of lateral velocity variations, and frequency and spatial domain algorithm of finite difference methods for simple, good stability, can adapt to the speed of longitudinal and lateral variation, but offset steep faulted strata there are many problems Platform: |
