Methods A life-size plaster cast of human head was used as the anthropomorphic model. Fifteen experimental conditions were studied. Nine linear distances between landmarks and Nasion were measured each time. These were compared to the standard anthropometric measurements using the same landmarks.

以石膏头像为研究对象，用系统在15种不同条件下测量模型面部9个点至鼻根点的距离，以用游标卡尺得到的测量结果为评判标准与前者比较。
