of little finger.And the mean value of each finger had a significant difference between males and females(P0.05).Along with the increasing deviation value of FRC between corresponding fingers,the variety trend of the frequency was gradually reducing,and an overwhelming majority(88.2%) of the value was less than or equal to 3.The frequency distribution of TFRC was close to a normal distribution.The mean value of atd angle was 40.27?4.34 and that of tPD(12.46?4.66)%.Both of atd angle and tPD had a significant difference between males and females(P0.05).The frequency of tPD under 15% was 72.5%,and none was over 30%.Conclusion The distribution of FRC and triangle in corresponding fingers of Bai nationality is symmetric and it shares some common features with that of other ethnic groups with its own characteristics.
