采用回归分析方法研究了现代长尾鲨Alopias vulpinus（Bonnaterre）（Lamniformes：Alopiidae）的齿冠高度（CH）与体长（TL）之间的关系。结果表明：1）通过替换，每个牙齿的CH的增加与TL的增加成比例，2）CH可用于预测TL，以及3）与近中定位的牙齿相比，远中定位的牙齿通过替换发育得更快。本文提出的回归方程可用于估算Alopias化石的热释光。
The relationship between the height of tooth crown (CH) and total body length (TL) in the modern common thresher shark, Alopias vulpinus (Bonnaterre) (Lamniformes : Alopiidae), is examined using regression analyses. The results suggest : 1) that an increase in the CH of each tooth through replacement is proportional to the increase in the TL, 2) that the CH can be used to predict the TL, and 3) that distally located teeth develop faster through replacement compared to mesially located teeth. The regression equations presented here can be used to estimate the TL of fossil Alopias .
