我国东南部地区是经济最发达、人口最稠密的地区,地质、物探工作程度高,出露于现代剥蚀面的、易发现的矿床均已做过工作,但对该区江河下游大面积的普遍覆盖区,小而富的隐伏矿床有待发展.这方面地质和物探的理论和方法技术也有待于发展.根据武汉地院所作的工作表明,在二层断面、均匀外电场的条件下,第二层介质中的球(柱)状极化体在地面产生的极化率异常极大值η_s~max 见下表:
The southeastern part of our country is the most economically developed and densely populated area with high degree of geology and geophysical exploration. Most of the easily discovered mineral deposits exposed to the modern denudation surface have done their work, but large areas of the lower reaches of the Yangtze River are common According to the work done by Wuhan Institute, it shows that under the conditions of the second-level section and the uniform external electric field, the second Pole-like polarizers in the medium have anomalous maximum polarizability η_s ~ max as shown in the following table:
