摘　　要：可控震源输出信号的畸变问题由来已久,引起的争论也最多。针对震源输出信号的畸变,作者2007年在物探装备上发表过一篇文章:从分析畸变参数的引入、畸变控制以及结合地球物理勘探的需求,并通过一个研究实例来研究对震源输出信号的畸变控制原则及实施方法。十年过后,特别是低频地震技术的推广应用,有一些问题需要进一步澄清,使更多的应用人员通过分析可控震源输出信号的畸变变化,探讨如何更科学地选择可控震源的激发参数、更合理地评价震源的激发质量及对可能出现的震源故障问题提前预警。The distortion of the vibrator output signal has a long history,and the controversy has been the most. On this issue,the author ever published an article on Equipment for Geophysical Prospecting in 2007. From the analysis of the introduction of distortion parameters and the control of distortion, combined with the needs of geophysical ex- ploration,and through a research example, the principle and implementation method of distortion control of source output signal are studied in the article. Ten years later, the popularization and application of low frequency seismic technology, there are some problems needing to be further clarified, so that more applications can analyze the vibrator output distortion and discuss how to choose the excitations of the vibrator more scientifically, evaluate the excitations of the source and predict the possi- ble source failures.
