麋鹿鹿角的结构形态及其密度

Relationship between the structure morphology and density of the elk's antler

为研究麋鹿鹿角的结构形态及其密度与年龄的关系,取各年龄段的鹿角进行分割,采用流体静力称衡法测量鹿角不同部位的密度,分析年龄对鹿角密度的影响。结果表明:麋鹿鹿角的各部位密度和年龄有着密切的关系,鹿角基部密度在2岁时达到高峰;中部则在3岁时达到高峰;4岁时尖端密度达到顶峰,各部位的鹿角密度曲线随着年龄的增长,密度逐渐降低,趋于平缓。

For the relationships between the structure morphology, age and density of the elk＇ s antler, the cut antlers density in different age and different part were measured by Hydrostatic says scale method to explore the influence of age on density. The experiment results showed that ： elk＇ s antler density in different part has close relationship with the age. Base density reaches the peak value when the elk is at two years old, while the central part at three years old and the top end at four years old. With the advance of age, the density decreases gradually and then tends to be gentle.
