1) spherical chain
球面运动链
3) hammer thrower
链球运动员
1.
The paper photographed the first 8 female hammer throwers of the National Trackand Field Tournament dynamically,3-dimentionally and,closely.
研究结果表明:掷链球最后用力技术由单支撑最后用力阶段和双支撑最后用力阶段两部分构成;单支撑最后用力阶段开始时机应在链球摆过最后一圈高点处于方位角200°~230°范围内;我国优秀女子链球运动员单支撑最后用力阶段肩髋轴间夹角较小,链球与肩轴的夹角较大,链球加速距离缩短,导致链球速度降低。
2.
The strength levels of 21 Chinese elite male hammer throwers were analyzed by looking up literature, by investigation and by mathematical statistics.
采用文献资料法、调查法、数理统计法 ,对我国 2 1名优秀男子链球运动员的力量素质进行了研究。
4) spherical motion
球面运动
5) planar kinematic chain
平面运动链
1.
We extend the traditional method by replacing a low pair with a higher pair,and the use of the method can produce all possible structural types of a planar kinematic chain with multiple joints and higher pairs in accordance with the adjacent matrix of the kinematic chain of a planar link.
提出了含复铰有高副平面运动链结构类型综合的邻接矩阵方法。
2.
This paper presents an adjacency matrix method for identifying topological symmetry to planar kinematic chains with multiple joints.
提出了识别含复铰平面运动链拓扑对称性的邻接矩阵方法。
3.
This paper presented a classification method to planar kinematic chains with multiple joints and higher pairs based on structural characteristics.
提出了基于结构特征的含复铰和高副平面运动链的分类方法。
