1 材料及方法1.1 调查了浙江地区出土颅骨297个,齐齐哈尔地区颅骨151个,调查顶枕缝、顶间缝的出现率,并根据形态及位置进行分型.1.2 对顶枕缝及顶间缝进行测量.取法兰克福平面水平位.设人字缝顶点(人字点)为O点,顶枕左端与人字缝的交点为a点,右端与人字缝的交点为b点,顶枕缝的顶点为c点,抗外隆突火端为d点,在a点与b点之间,于颅骨表面作一水平的弧形连张,由c点向ab线作垂直线,与之相交点为e点.用软皮尺沿颅骨外表面测量下列数据:(1)顶枕缝的长度沿缝弧距(acb);
1 Materials and Methods 1.1 Investigation of the 298 skull unearthed in Zhejiang Province, 151 skulls in Qiqihar region to investigate the incidence of top and back medial seams, and according to the shape and location of the subdivision.1.2 on the top pillow seam and the top seam Take the level of the plane in Frankfurt. Set the gable crest point (point) to O point, the top of the left pillow and the herringbone point of intersection of a point, the right end and the herringbone point of intersection point b, the top pillow seam The vertex is c point, the anti-external protuberance fire end is d point, between point a and point b, on the skull surface for a horizontal arc Zhang, from c to ab line for the vertical line, intersect with it Point is point E. Measure the following data along the outer surface of the skull with a flexible tape measure: (1) the length of the top pillow along the arc acb;
