斯林格兰姆法和突拉姆法一样,都属于低频电磁感应法,不过斯林格兰姆法采用偶极的发射线框,是一种动源的感应法,在苏联称作偶极剖面感应法.目前所用的标准仪器有瑞典的探矿枪、电磁枪、有加拿大的SE-600电磁水平(垂直)线框探矿仪.仪器的结构都相同,只是仪器的电子线路和工作频率有少许差别.仪器包括两只轻便的线框.一只是发射线框,另一只是接收线框.两只线框按不同方式排列,构成各种不同的线框系统.其中最常用的是共面的水平线框系统,即两线框相隔一定距离平行地面在同一水平内安放,在此情况下发射线框建立的一次场垂直地.面地下导电矿体中产生的涡流在空间形成二次场.此二次场的垂直分量可以分解成一个与一次场相位相同的分量(即 Similar to the Slungram method and the Sudram method, all belong to the low-frequency electromagnetic induction method, but the Slingamme method uses a dipole launch wireframe, which is a moving source induction method. In the Soviet Union, it is called dipole section induction France currently used standard instruments are Sweden’s prospecting gun, gun, Canada’s SE-600 electromagnetic horizontal (vertical) wireframe prospecting instrument.The structure of the instrument are the same, but the instrument’s electronic circuit and the operating frequency of a little difference. The instrument consists of two lightweight wireframes, one for emitting wireframes and one for receiving wireframes. Two wireframes are arranged in different ways to form a variety of wireframe systems, the most commonly used of which are coplanar horizontal wireframes The system, that is, the two wire frames are spaced apart from each other at a distance parallel to the ground and placed in the same horizontal plane. In this case, the primary field established by the transmitting wire frame forms the secondary field vertically in the space. The vertical component of a field can be decomposed into a component of the same phase as the primary field (ie
