电磁slinggram法可同时提供三类信息：(1)地面视电阻率；(2)其表观敏感性；(3)埋藏金属物体的特征特征。要建立具有这三种测量能力的仪器，需要选择适当的参数，包括频率、线圈间距和线圈方向，以及考虑到地面电阻率和磁化率的计算。两个例子表明了slinggram方法在考古应用中的价值：(1)用减少采样的宽网格技术测量了一个加洛罗马陶器车间的表观磁化率；(2)对位于沼泽中的青铜窖藏遗址的研究。通过使用多个接收器的装置的进一步研究，可以提高slinggram方法的能力，这将增加调查的深度。使用几个频率会超过……
The electromagnetic Slingram method can provide three types of information simultaneously: (1) the apparent resistivity of the ground; (2) its apparent susceptibility; and (3) the characteristic signatures of buried metallic objects. To build an apparatus with these three measurement capabilities requires an appropriate choice of parameters, including frequency, coil separation, and coil orientation as well as calculations which take into account the electrical resistivity and the magnetic susceptibility of the ground. The value of the Slingram method for archaeological applications is shown by two examples: (1) a Gallo‐Roman pottery workshop investigated with measurements of the apparent susceptibility using a reduced sampling wide mesh grid technique; and (2) the study of a Bronze hoard site located in a marsh. Capabilities of the Slingram method may be improved by further study of an apparatus using several receivers which would increase the depth of investigation. Use of several frequencies would over...
