“别种”是民族史研究中经常会遇到的一个词,能否对它正确理解,对判定一个民族的族属问题至关重要。它有“分出的种”、“不同的种”两个含义。前者主要体现包含关系,有的存在血缘关系;后者主要体现并列关系,但都有地缘关系和外在的相似点。 “Other” is a word often encountered in the study of the history of nationalities. Whether it can be properly understood or not is crucial to determining the ethnicity of a nation. It has two meanings: “seed”, “different seed”. The former mainly embodies the relationship, some of the existence of kinship; the latter mainly reflects the juxtaposition, but there are geographical and external similarities.
