摘　　要：主要介绍了地磁场相对强度研究的两种方法:常规归一化方法和假-Thellier方法的基本原理和做法,探讨了前者选择不同归一化参数的一般原则,并对比了两种方法的差异,指出地磁场相对强度研究方法在目前海洋沉积物定年研究中的应用方向和前景。Two main types of methods for relative paleointensity study are introduced in this paper. One is traditional normalization method and the other is pseudo-Thellier method. First, general principles and procedures of the two methods are summarized, then selections of different normalizers in traditional normalization method are discussed, and also comparison is done for the relative paleointensity results from the two methods used, especially in Ontong Java Plateau （OJP） sediments. It is predicted that there is broad perspective of relative paleointenslty study in dating marine sediments and probing the interior of the Earth.
