摘    要：论述了用低频电阻率微测深法无损检测厚度为几厘米至几十厘米的混凝土覆盖层的原理,重点讨论了其检测仪器设计中频率选择、高接地电阻条件下的观测精度、直读视电阻率和供电电源轻便化等问题。

Abstract: The theory of non-damage measurement for the concrete covering-layer by the low frequency resistivity microsounding is expounded in brief,whose thickness is several or tens ofcentimetres. The problems in the design of the measuremerit instrument are discussed, especially on the frequency selection,measuring accuracy under the high earth-connection resistance, directly-reading resistivity and lightening the supply .
