文章通过对新郑地区四处两周墓地日用陶器墓的研究,从陶器组合、墓葬大小及葬具等三方面,观察到日用陶器墓呈现出三种不同的等级差异。等级差别揭示出郑国平民阶层内部身份等级再划分的事实,这种等级划分可能是军功爵制下的合法制度。 Through the study of daily pottery tombs in two cemeteries in Xinzheng area, the article observes that there are three different levels of pottery tombs in terms of pottery assemblage, size of burials and burial supplies. The differences in rank reveal the fact that the internal status of the class of civilians in Zheng Guo is subdivided. This classification of rank may be the legal system under the system of military power.
