查询词典 distances

By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

In this paper was obtained minimum point of sums of distances to isosceles triangle certainly was in median line of base of the triangle,and minimum point of quadratic sums of distances to every vextex in general triangle just was bara-center ofthe triangle.

对等腰三角形，得到了到各顶点距离之和的最小值点必在底边的中线上；对一般的三角形，获到了到各顶点距离平方和的最小值点就是三角形的重心。

While matching, only the principal component directions corresponding to the rows of the same serial numbers in searching area are needed to be extracted for the computation of projection value so as to form the vectors of projection values. The distances between MM-vectors and the vectors formed by projection values are computed, and whether the two kinds of vectors are matchable should be in accordance to those distances.

在匹配时，只需抽取搜索区域中相同序号的列向相应的主元方向作投影运算，从而构成投影值向量，进而计算该向量与预处理中所得的最大最小值构成向量间的距离，从而根据距离的大小判断是否匹配。

Secondary pollinators are diurnal hawk moths and butterflies. Bombus briviceps and Bombus sp. are nectar gatherers. The mean nectar sugar concentration is 29.5%. The proport ion of seed is 86. 5%. Percentage seed germination under controlled conditions is 23.1 %. Distances that seeds are ejected ranged from 0.58-1.17 m. The distances that pollen spread is 29cm. Pollen viability is highest on the day of anthesis and thereafter decreased.

匍匐凤仙花的主要传粉者是蜜蜂和熊蜂，次要传粉者为白天活动的天蛾和蝴蝶，另外还有两种花蜜窃取者；花蜜糖平均浓度为29.5％；种子产生率为86.5％，种子萌发率为23.1％，种子散布距离为0.58-1.17m；花粉流为29cm；花粉活力在第一天最高，第二天次之，第三天显著减弱；P／O值为

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

The interdental distance between the mesial groove of the first molars and distal groove of the second molars was measured on the maxillary dental casts. The interdental distances at the end of experimental tooth movement and retention were calculated. The effectuality of retentive appliances was evaluated by comparing the tooth movement distances between the experimental side and control side.

在加力结束后和保持结束后即刻制取上颌石膏模型，测量所有模型的第一磨牙牙合面近中沟与第二磨牙牙合面远中沟的距离，计算加力结束后与保持结束后的距离，比较实验侧与对照侧的牙齿移动距离，评价保持装置的有效性。

When two particles couple themselves in a singlet at short distances (one with spin up and one with spin down) the new nonlinear, nonlocal and nonpotential forces due to deep wave-overlappings are so attractive to overcome possible repulsive Coulomb forces, and permit new bound states at short distances which simply cannot be conceived - let alone treated - by quantum mechanics and chemistry.

当两个粒子在很小的作用距离内相互偶合成为零自旋态〔一个上旋而另一个下旋〕，深深重叠在一起的波导致新型的非线性、非局部和非潜势力的引力大到得以克服相互排斥库伦力，允许很小相互作用距离内的一种新的限制状态。量子力学和量子化学无法考虑，更不用说去处理，这种新的限制状态。

As the distances between coordination sites of auxiliary ligands increasing, the distances between adjacent two-dimensional [Er(5-NO_2-bdc)_2]~- anion layers enlarged. As the bulks of auxiliary ligands largening, the coordination configuration of Er optimized and the dimensions of coordination polymers increased.

增大辅助配体的配位点之间的距离，增大了二维[Er(5-NO_2-bdc)_2]~-阴离子层之间的距离；增大辅助配体的空间位阻，优化了金属离子的配位几何构型，使配位聚合物的维度增大。

The mainly employed cognitive tacts includes global descriptions of distances, distances in conventional unites, locations and guess, among which locations and distances in conventional unites appear to be more important.
