The upgma dendrogram illustrated close relationship between no . l and 25 ; 18 and 21 ; 23 and 24 ; 4 , 26 and 17 ; 12 , 27 and 15 etc , which suggested that upgma results were in accordance with morphological data among these subgroups , while others could not “ ） 6 、 10 、 11的株型、叶形相似，新叶叶色相同，但从rapd分析结果来看，并不如此。这也说明种内个体之间虽然距离较远，但在形态上还不一定能体现出明显的差异。
Research on kinematic analysis founds the theoretic base for farther study . ihca will be a new way to solve the inverse kinematic problem . it may be used for reference to the blending of multi - subject that the advanced technology in intelligent artificial is successfully used to solve the inverse kinematic problem 对水轮机叶形现场检测机械臂运动学的研究为进一步的控制研究打下了良好的理论基础；智能登山法巧妙的将人工智能中的搜索算法应用于机器人运动学逆解的求取，为机器人领域求取运动学逆解提供了一条新的途径，对实现了多学科之间的融合也有一定的借鉴意义。
The research on this aspect just starts and the study about manipulator for measuring blade shape of water turbine runners in site is almost a blank in our country . in this paper , according to the practical situation , the special structure of manipulator was designed , the structural characteristic and the working principle were described , the geometrical model was built , the kinematic analysis was described by d - h , and the inverse solution was gotten by analytic method 本文从大型水轮机叶形现场检测的实际出发，针对性的设计了水轮机叶形检测机械臂的特殊结构，分析了其结构特点及工作原理；在此基础上，建立了检测机械臂的几何模型，采用d - h法对其进行了完整的运动学分析，使用解析法获得了运动学逆解。
Only no . 13 and no . 15 had same color in spring and in autumn , while others showed slight different in color in spring and in autumn . the clustering analysis on the spring morphological chatactreistics depicted 4 groupings of the 21 accessions . there were similarities within each group especially for leaf and / or flower color （ 3 ） 4 、 17 、 26号的秋季花色相同都是6lb ，且4号与17号春季花色也相同，都是60b ，它们在叶色、叶形上也很相似，形态聚类结果与kapd聚类结果相吻合。
In p . salicina , leaves with a green petiole were long ellipse and wedge - like at the base , with no hair on the surface and petiole . in p . ameniaca , the leaf was rough on the surface and had hair . with its own germplasm characteristics , p . mume was close to p . ameniaca in genetic relationship 李类植物的叶形为长椭圆形，叶基楔形，叶面无毛，叶柄绿色且无毛；杏类植物叶面粗糙、有毛；梅类植物接近于杏类，与杏类植物有较近的亲缘关系，但又表现出丰富的种质特异性。
