四足型灵长类踝关节的生物力学研究

对猕猴属５种踝关节和跟骨生物力学和多变量分析的结构表明，踝关节的运动主要与距骨关节面的形态有关。楔形指数和跟骨指数是区别种间差异的重要指标。结合生态学观察的结果推测，短尾猴和藏酋猴的运动方式最为接近，表现出适应地栖四足型运动的特征，而豚尾猴和熊猴有关对的树栖运动方式，猕猴的运动介于两者之间，既有一定的地栖性运动，也有较大的树栖性运动。

COMPARATIVE STUDIES ON ANKLE JOINTS IN QUADRUPCEPS

The biomechanical and multivariate studies on the articulatio talocrueralis and calcanea in five species of macaques,which belong totally to quadrupeds,show that, functionally,the morphological structure of talus plays important role in motions and is of importance in identifications of species. Wedging index is the main factor for distinctions of those macaques. According to the information of field survey and investigation and the results of discrinminate functional and principal component analyses on some indices and variables of ankle joint and calcanei of them,we might infer that there are more similar locomotor behaviors in stump-tailed monkey and Tibetan monkey which exhibited more adapted characters for moving on the ground . In constrast, as-samese monkey and pig-tailed monkey show arboreal quadrupedal motions. But,rhesus monkey is to be intermediat position between more terrestrial and highly arboreal forms.
