三截

On the basis of distributive shapes of point collection on the Poincare section, define three indexes to quantitatively describe the distribution of point collection. Which are distance between two adjacent points, diffused angle and distance between every point and center point of point collection.

以庞卡莱截面上RR间期序列的点集分布形式为基础，提出点集中相邻点间距离、扩散角度和点到点集中心距离三项指标，用以定量地衡量点集的分布形式。

The results of three cladistic methods showed: the consanguinities of different genera in a same tribe were closer, such as Chalcis and Conura, Trigonurella, Megalocolus and Trigonura; the consanguinities of genera between different tribes were farther, such as Chalcis and Brachymeria, Dirhinus and Hallichella; Chalcis, Conura, Brachymeria and Epitranus were the most primitive relatively, Tainaniella and Oxycoryphe were the most evolutional, the consanguinities were the farthest between the former and the latter; the genera with the closest consanguinities were: Tainaniella and Oxycoryphe, Proconura and Nipponochalcidia, Chalcis and Conura, Megalocolus and Trigonura, they were regarded as 4 pairs of sister groups.

三种支序分析方法一致支持的结果为：同一族内成员之间亲缘关系较近，如小蜂属和卡诺小蜂属，微三角小蜂属、细尾小蜂属和三角小蜂属之间；不同族内成员相互之间的亲缘关系则较远，如小蜂属和大腿小蜂属之间，角头小蜂属和截胫小蜂属之间；小蜂属、卡诺小蜂属、大腿小蜂属和脊柄小蜂属相对最为原始，而泰内小蜂属和背突小蜂属最为进化，前者和后者之间的亲缘关系最远；亲缘关系最近的有：泰内小蜂属和背突小蜂属，泊卡小蜂属和日本小蜂属，小蜂属和卡诺小蜂属以及细尾小蜂属和三角小蜂属，它们各自之间都构成姊妹群关系。

而几天来观看鹤龄的言辞：卵蛋里面长着毛；鸡的脚可以数出三只；郢都内就存在着天下；狗也可命名为羊，马能够说是卵生的；虾蟆可以说是长有尾巴；火本身并没有热感；山中的回音证明大山也生出了口；车轮永远不会着地；眼睛缺乏看视实质的能力；指认外物永远达不到事物的实际；乌龟可能比蛇还长；角尺不能画出方形，圆规也不能用来画圆；自己的榫眼与榫头不会完全地吻合；飞鸟的身影也可说不曾有过移动；飞逝而去的箭头有停留、也有不曾停歇的时刻；小狗可以不是狗；黄马、黑牛的称谓可以数落出三个；白狗也可以叫它黑狗；称作孤驹应该说它不曾有过母亲；一尺长的棍棒，每天截取一半，一万年也分截不完，一篇滥调没完没了。

Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5cm above the dome of acetabulum, which were fixed with ATMF'S or steel plate respectively. The animals were sacrificed and specimens were procured at 2, 4, 6, 8 and 12 weeks after operation. Samples from the fracture gaps were investigated by histology of HE and Masson staining, image pattern analysis of new bone formation.

The paper reviews the development in the analytical theory of mechanical behavior of composites, pointing out the problems existed, presenting creatively the concept of yarn state, solving the descriptive problem of perform structure of any woven composites and laying the foundation for predetermining the elastic behavior of 3-d woven composites with computer. On the basis of yarn state, the relative cross section deformation theory is introduced, the yarn cross section deformation is studied, and the experiential formula is described in the paper on the basis of experiment. The crimping state of yarn is studied, the classical "straight warp view"is modified, and the crimp height value of crimped yarn is studied. At the same time, with shrinkage rate sine method, the paper proposes the idea which imitate the shape of crimped yarn. With the third power template curve, the paper describes the microgeometry structure of fabric, finding a brief and precise approach for the calculation of mechanical behavior of composites.
