槽波成因的简要分析
|
摘要
介绍了槽波勘探技术的发展历史,指出大部分专著及文献中对于槽波形成成因的表述不当。结合波的干涉和波的叠加理论以及斯奈尔定律,对槽波的成因进行定性分析,分别从波的干涉的3个条件进行分析,阐明了不管是Rayleigh型槽波还是Love型槽波,都符合波的叠加理论,而非波的干涉;通过公式推导,再次印证了槽波的形成符合波的叠加原理,是由波的叠加形成,只有少量频率成分的槽波是由干涉形成。
The development history of ISS exploration technology was introduced,and it was pointed out that most of the monograph and literature do not express the cause of formation of ISS.Then,combining the theory of wave interference and wave superposition,and Snail′s law,qualitative analysis of the cause of slot wave was made.The three conditions of wave interference were analyzed respectively,and it was clarified that both Rayleigh-type and Love-type slot waves conform to the superposition theory of waves,not to the interference of waves.Lastly,through the formula,it was proved again that the formation of groove wave accords with the superposition principle of wave,and it was formed by the superposition of waves,and only a small number of frequency components were formed by interference.
