引言连续振动(可控振源)技术二十余年的经验说明,著名的、由连续振动系统创始人提出的扫描信号(Crawford et al,1960)不仅十分适应于地球的物理性质,而且适用于那时采用的技术设备。今天,它仍然不乏支持者。虽然已经提出了许多别的形式的信号,但还没有一个比得上扫描信号,特别是在考虑到野外 INTRODUCTION The experience of more than twenty years of continuous vibration (controlled vibration source) technology shows that the famous scanning signal proposed by the founders of continuous vibration systems (Crawford et al., 1960) is not only well adapted to the physical properties of the Earth but also to At that time using the technical equipment. Today, it still has no shortage of supporters. Although many other forms of signals have been proposed, none of them is comparable to scanning signals, especially considering the field
