地震道显示，以波形的形式显示地震剖面，非常有用。(draw seismic section)

This handbook is intended for anyone who wants a comprehensive survey of Fortran 90, including those familiar with programming language concepts but unfamiliar with Fortran. Experienced Fortran 77 programmers will be able to use this volume to assimilate quickly those features in Fortran 90 that are not in Fortran 77 (Fortran 90 is a superset of Fortran 77).

基于 的窗函数的各种窗函数的设计以及各个函数的性能参数分析以及仿真波形(Window function based on a variety of window function design and performance parameters of each function and the simulation waveform)

仿相环功能-锁频环鉴别结果-锁频环跟踪结果(Frequencylockloop-Identification results- frequency PLL frequency lock loop tracking results)

这是信号处理中循环谱密度的一个DEMO，有些文章中称其为循环平稳信号的组合切片(A demo of cyclic spectra density. it also can be called combinated splice on cyclostationary signal in some papers.)
