下颌骨的研究不论在国内还是国外均有报道。国内有俞东郁、张富安、汪兆麟等氏。河北新医大《人体解剖学》亦有记载。国外报道亦较多。但目前国内关于下颌骨的全面测量的报告很少,西北地区现代人下颌骨的测量统计也尚无报告资料。本文研究的目的在于探讨下颌骨在种族、地区方面有无差异,为我国体质人类学贡献点滴资料. Mandibular research has been reported both at home and abroad. There Yu Yu, Zhang Fuan, Wang Zhaolin other’s. Hebei Medical University, “Human Anatomy” also recorded. Foreign reports are also more. However, there are few reports on the comprehensive measurement of the mandible in China at present. There is still no report about the measurement of the mandible in the modern northwest area. The purpose of this study is to explore the mandibular differences in race and region, contributing a bit of data for physical anthropology in our country.
