对区域性电法普查的一些看法

本文首先分析了区域性电法普查的必要性,认为它将可能带动物探的又一次大发展。其次讨论了区域性电法普查的可能性,指出电法探测中的一些方法及变种所探测的对象都是相同的,认为对各变种持“各有优劣,择优采用”的观点是实施区域性电法普查的思想障碍。然后对目前应用较广的各种方法进行了分析比较,得出了偶极装置的幅频激电方法是最适宜的区域性电法普查形式。最后对实施区域性电法普查的资金、组织等问题提出了一些看法。

SOME OPINIONS ON REGIONAL ELECTRICAL SURVEY

This paper begins with an analysis of the necessity of regional electricalsurvey, holding that this method might bring about another drastic developmentof geophysical prospecting. Then it discusses the feasibility of regional electricalsurvey, indicating that valieties of electrical procpecting techniques are all dire-cted at the same target, and thus the idea "every variety has its own meritsand demerits, and therefore better one should be adopted" hinders us from con-ducting regional electrical survey. Analysis and comparison have also been madefor various techniques and facilities widely used at present. On such a basis, it isbelieved that the amplitude-frequency IPtechnique with dipole device is themost effective means for regional electrical survey. In addition, some opinionsconcerinng the performance of regional electrical survey, such as fund and org-anization, are also given in this paper.
