一、引言视电阻率(ρ_s)曲线变化常常是多种多样的,引起异常的原因也是极其复杂的,因而对视电阻率异常很难作出肯定判断。82年4月中旬以来,渡口视电阻率产生了十分有趣的异常变化,引起了省内外地震工作者的密切注意。笔者会同渡口中心站的同志赴现场考查后,提出可能是灌水影响的一种解释。 I. INTRODUCTION The variations of the apparent resistivity (ρ_s) curve are often varied. The cause of the anomaly is also extremely complicated, so it is difficult to make a positive judgment on the apparent resistivity anomaly. Since mid-April of 82, there has been a very interesting and unusual change in apparent electrical resistivity at the ferry crossing, causing close attention of earthquake workers inside and outside the province. After going to the site with my comrades at the ferry terminal, I put forward an explanation which may be the impact of irrigation.
