劳脫巴赫(Lauterbach)等人自1952年起在微磁測量(Mikromagnetik)方面进行了一系列的工作并发表了有关的文章。他所指的微磁測量是在比較小而典型的地段里(10×10至50×50米)进行很密的測量,測点距离一般都在5米以內。因此所要求的精密度往往就比較高。这样就能取得比一般磁测細致得多的磁性强度的变化,面积小到1×1米的磁性异常也能在測量結果中反映出来。这个方法适用于測量露出地表或者埋藏深度小于5—10米的岩层或岩体。被測的岩体表面的起伏不可十分强烈而且盖层的微磁变化也不可太大。他使用两部范謝劳式线秤(faderwaage Hach Prof.Fauselau),一部固定在一个測点,另一部在其他測点进行測量并不断地同固定的一部进行校正。他們所測量
Lauterbach et al. Have conducted a series of work and published articles on micro-magnetic measurements (Mikromagnetik) since 1952. He refers to the micro-magnetic measurement is relatively small and typical of the lot (10 × 10 to 50 × 50 meters) for a very close measurement, measuring points are generally within 5 meters. Therefore, the required precision is often higher. In this way, it is possible to achieve a much greater change in magnetic intensity than the general magnetic measurement. Magnetic anomalies as small as 1 × 1 m in area can be reflected in the measurement results. This method is suitable for measuring rock or rock mass exposed to the surface or buried at depths of less than 5-10 m. The undulation of the surface of the rock mass under test can not be very strong and the micro-magnetic changes of the cover layer should not be too large. He used two Faderwaage Hach Prof. Fauselau, one fixed at one measuring point and the other measuring at other measuring points and constantly calibrating with a fixed one. They measure
