摘　　要： 食指和无名指指长之比(D_(2)∶D_(4))与人类运动能力等特性相关.探讨网球运动员与普通大学生的D_(2)∶D_(4)比率差异.活体测量受试者的右手D_(2)∶D_(4).数据处理采用二分类Logistic回归模型和树模型.因变量为网球运动员组和普通大学生对照组,自变量为右手D_(2)∶D_(4)和性别.结果显示:无论男生和女生,网球运动员的D_(2)∶D_(4)明显低于普通大学生. The second to fourth finger length ratio (D_(2)∶D_(4))is thought to be related to diverse traits including athletic ability.To examine the relationship between D_(2)∶D_(4)and sports ability in tennis players and college students.The length of the right hand fingers were measured in vivo to estimate D_(2)∶D_(4).Tennis players and ordinary college students were used as the independent variable,and right-hand D_(2)∶D_(4)ratios and gender were used as the dependent variable.All the statistics were computed with binary logistic regression model and tree model.Results showed that the D_(2)∶D_(4)of tennis players were significantly lower than those of ordinary college students.
