摘要
本文报道人牙本质试件在拉力状态下的泊松比。用成年人的新鲜切牙、尖牙、双尖牙和磨牙制作１０个试件进行测试，测得人牙本质的泊松比为０．２８－０．３８，平均值－μ＝０．３３，标准差０．０３。同时测得人牙本质的弹性模量为１７．２－２１．４ＧＰａ，平均值Ｅ＝１９．８３ＧＰａ，标准差１．３８ＧＰａ。
This paper gives the Poisson's ratio of human denim,which was calculated by Poisson's formula. 10 specimens made from incisor,canine,bicuspid and molar were measured. The Poisson's ratio measured varied from 0. 28 to 0. 38 with 0. 33 the average. At the same time the measured tensile elastic modulus of denim Varied from 17. 2 to 21. 4 GPa with 19. 83 GPa the average.
