查询词典 tarsometatarsus

In particular it can base on the analyses of the diversity of shape and structure of tarsometatarsus of living birds and its corresponding function,to study the shape and habit of birds in the early stages,at the same time can discuss the evolutive law of functional behavior of birds in the different periods of the geologic history further too.

特别是通过对现生鸟类跗跖骨形态结构多样性与对应功能的分析，可以此作为研究早期鸟类形态习性的参考依据，同时也可进一步探讨不同地质历史时期鸟类功能行为的演化规律。

In this paper, 4 variables of the distal tarsometatarsus were also collected from 25 specimens of fossil birds belonging to 14 genera of Early Cretaceous birds from Western Liaoning in China. Analyses of these variables have also proven to be useful in distinguishing arboreal and terrestrial birds, and the result is generally consistent with a conclusion reached on the basis of other analysis, i.e. those based on the claw geometry and toe proportion.

通过对在中国已发现的25例中生代鸟类跗跖骨远端4个变量的统计分析，表明它们同样具有区别树栖和地栖鸟类的显著意义，而且分析的结果与参考鸟类其他特征（如爪的形态、脚趾的比例等）所得出的结论基本一致。

Research on the diversity of shape and structure of avian tarsometatarsus, not only did it present evidences to realize the ecological habit of birds of different species, but made the knowledge of functional behavior of avian hindlimbs perfect progressively also.

鸟类跗跖骨形态结构多样性的研究不仅为了解不同类型鸟类的生态习性提供证据，也使鸟类后肢骨骼的功能行为学得以逐步完善。

Statistic analyses of the proportions of the three major bones of the hindlimb（femur, tibiotarsus and tarsometatarsus）from 137 skeletons belonging to 59 families of 18 orders of living birds with different perching habits show that they can be used as a good indicator of their living styles.

通过对18目59科137例现生不同栖息习性鸟类的后肢3块骨骼长度比例的观察和特征分析，推断出鸟类的栖息习性与后肢3块骨骼中各骨骼长度所占总长度的比例存在密切的关系。

Research on the diversity of shape and structure of avian tarsometatarsus, no only did it present evidences to realize the ecological habit of birds of different species,but made the knowledge of functional behavior of avian hindlimbs perfect progressively also.

鸟类跗跖骨形态结构多样性的研究不仅为了解不同类型鸟类的生态习性提供证据，也使鸟类后肢骨骼的功能行为学得以逐步完善。

Research on the diversity of shape and structure of avian tarsometatarsus,not only did it present evidences to realize the ecological habit of birds of different species,but made the knowledge of functional behavior of avian hindlimbs perfect progressively also.

不同类型鸟类跗跖骨的形态多样性分异反映了鸟类对外界环境的选择性适应。1鸟类跗跖骨的特征1·1鸟类跗跖骨的组构在鸟类后肢骨骼系统中，其下端的跗跖骨为一块愈合完整的骨骼，这亦成为鸟类特有的骨骼结构，与其他四足动物(跗骨、跖骨由多块分离的骨骼组成)明显不同，鸟类由于飞行使得

Sanctus. Mandibular fenestra expanded anteriorly. Maxilla protruding more anteriorly than in C. sanctus. Wing claw less developed. Sternum relatively elongate with a "V"-shaped anterior notch. Sternum with a pair of short posterior proceses. Tarsometatarsus relatively short. Pygostyle expanded distally.

上颌骨较圣贤孔子鸟向前突出，指骨爪没有圣贤孔子鸟那样伸长、强壮，胸骨比较拉长，前喙中央有一凹刻构造成&V&字形，同时胸骨两侧有一对短的后侧突，跗蹠骨较圣贤孔子鸟短，以及尾综合、骨末端膨大。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
