| 摘 要： | 地球物理勘察是一种体积勘探，其观测值不仅与测点附近的物性、地质条件有关，而且还取决于装置以及物理场主要作用范围内物性体的分布。为了压制非目标因素，突出有效异常，采用适当的数学手段对观测数据进行处理是必要的。编制异常等级断面图就是一种行之有效的方法。详细叙述了异常等级断面图的编制程序和注意事项。实例介绍了在传统直流电法中的实际应用及其独特的地质效果。异常等级断面图适于在水文工程、环境物探中运用，其基本思路也可应用于其他诸多领域。

| Abstract: | Geophysical survey method is a kind of volume exploration.The observation is not only related to the geophysical condition near the observation points,but also dependent on the equipment and the physical body's distribution in the main action range of physical field.In order to inhibit non-object factors and give prominence to the efficient abnormality,it is necessary to adopt a rational mathematic method to deal with the observation data.It is effective to draw the abnormal class section.The authors depict in details the compilation procedures of abnormal class section and its points for attention.The example presents the application in electrical method of conventional direct current and the unique geological effect obtained.Abnormal class section is applicable in the fields like hydro-engineering and environmental geophysical exploration. |
