摘要/Abstract

摘要： 对28例太行山成年猕猴(♂10,♀18)的上、下颌颊齿齿冠面积进行测量。运用SPSS 10.0统计软件的多变量分析,选择有关颊齿变量建立性别判别函数。结果表明:猕猴颊齿具有明显的性差。选择不同的变量和选择不同的判别函数其性别正确判别率不同。上、下颌颊齿的性差有一定差异。使用逐步判别法建立判别函数,其性别正确判别率上颌颊齿为89.3%,下颌颊齿为92.3%。

Abstract: In this paper 28 (male 10 and female 18) cheek teeth samples of the adult rhesus macaques ( Macaca mulatta) in the Taihang Mountains were collected and 5 molar area variables (crown length multiplied by width ) of permanent cheek teeth were measured by the method suggested by anthropometry. Sexual discriminant functions were constructed by mean of Fisher’s method employing SPSS10.0 for windows. The statistical test showed that the correct sex discriminant rates of maxillary and mandible cheek teeth reached 89.13 % and 92.13 % respectively. The results of stepwise discriminant analysis confirmed the functions were suitable for sexual discrimination of the molar, and it suggested their high applicative values in practice.
