中文摘要：

文章结合文物及文献材料对明代颁赐藏僧象牙图章的特点、性质、渊源、使用的等级规范与功用等情况进行了探讨，认为这类印章是明朝官方颁给以喇嘛为主的低级藏僧的印信，在印文及款识方面具有官印和私印的双重特点，是明代新出现的印章类型。明代象牙图章的出现虽有历史渊源，但自成体系，与明朝赐封藏僧封号的规则及一类规谏、褒扬印有更直接的关系，并在现实中有实际功用。对象牙图章的研究能补明代印制之阙，还可窥探明朝治藏的政策与特点，意义重大。

They had the characteristics of both private and official seals in terms of the inscrip- tions on them and their design. They firstly emerged in the Ming Dynasty and a system of granting ivory seals were built then.
