中国人指型的观察从指远端相对长论指型

OBSERVATIONS ON THE DIGITAL TYPES IN CHINESE

本文就19-25岁青年700人(男女各半)观察了指远端的相对长。中指最长,拇指最短。环、食指之间的相对长可分为三型:甲型,食指长于环指,占13.9外;乙型,环指长于盒指,占78.70Jo;丙型,食指与环指等长,占7.4呢。在男女两性间,甲型的出现率女(190l0)高于男(8.9务),乙型的出现率,男(85多)高于女(72.3多)。在左右手之间,各型的出现率无显著差别。小指远端亦可依其与环指远侧指间关节纹的相对长分为三型:短型占61.9形,中间型占17.3务。长型占20.8多。短型小指男性出现率(49外)低于女性(74.9多)。从测量食、环指远端距中指远端的距离,证实观察的结果与测量的结果是吻合的。食、环、小三指相对长在左右手的对称情况是:完全对称占58.3多,部分对称占22.7多,完全不对称占4.6多。部分不对称占14.4多。部分刘一称和部分不对称的出现率,在男女之间存在着显著的差别。

The variations of the distal extent of fingers were observed on 700 Chinese youths,male and female were in equal numbers.The relative lengths of the ring finger and index finger could be classified into three types.TypeⅠ,the index was longer than the ring finger in 13.9%;typeⅡ,the ring finger was longer than the index in 78.8%;typeⅢ,the ring finger was of equal length with the index in 7.4%.The higher percentage of longer index was found in females than in males.Comparison was made with the reports from some other countries,and the characteristic of the longer index was found more prominent in Canadian and American males than in Chinese and Japanese males.The distance from the tip of the index or ring finger,to the level which crosses the tip of middle finger was measured.The results coincide with the above observations.Regarding the observations on the little finger,there was significant difference between males and females.The short little fingers occurred in greater numbers(74.9%)in females than in males.In comparison with the results from H.Blincoe,short little finger seems to be a physical characteristic of the Chinese females.Concerning the conditions of the relative lengths of the index,ring,and little fingers on both hands,the absolute symmetry was present in 58.3%,and complete asymmetry in only 4.6%.The incomplete symmetry and asymmetry were found to be present in 22.7%and 14.4%respectively,and significant difference was noted between males and females.
