摘要(Abstract)：
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D2∶D4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.
