【摘要】 用MT方法对一维地质体的探测能力进行研究。结果表明 ,在合适条件下MT方法的探测深度可达几千公里。但具体探测深度与异常体的电性、规模、围岩电性有关。一般来说 ,异常体规模越大 ,可探测深度越大 ;异常体与围岩的电性差越大 ,可探测深度越大

【Abstract】 In this paper the detecting ability has been studied for 1D electrical body with MT method. The results show that in proper condition detecting depth is several thousand kilometers with MT method. But clear detecting depth is relating to resistivity and size of abnormal body, and resistivity of wall rock .In generally , the more of the size of abnormal body, the more of detecting depth. The more of electronic difference between abnormal body and wall rock, the more of detecting depth.
