查询词典 cluster

Plates of globular cluster M3, taken with the 40cm refractor at Sheshan station of Shanghai Astronomical Observatory, are used by this work. The difference of epoch of these plates is up to 81years. The positions and absolute proper motions of 24 stars in ACT catalogue, which links with the Hipparcos Catalogue based on the International Celestial Reference System, are used as the reference frame. Using the central overlapping principle, the absolute proper motions of 534 stars in the region of about 100'×100' around the cluster are determined. After the membership determination of the stars which based on the data of proper motions, average absolute proper motion components for the cluster of -0.3±0.3 mas/yr in R.A.

本文使用上海天文台佘山40厘米折射望远镜拍摄的14张最长时间跨度为81年的球状星团M3底片的PDS扫描结果，使用与 Hipparcos星表相联系的基于国际大球惯性参考系的ACT星表中的 24颗恒星的位置和绝对自行为参考架，用中心重叠法进行天体测量归算，得到了这个星团中心附近100'×100'天区内534颗恒星的位置和绝对自行，并利用这些自行对成员概率进行了估算，得到这个星团的赤经方向绝对自行为- 0.3±0.3mas/yr，赤纬方向绝对自行为-3.1±0.3mas／yr。

The dendrogram shoe that the 55 materials were divided into five class at the line L_1,the agnate No.4 was a class and matriline longwangmao was a class,the other three agnate and hybrids were regular cluster,only agnate No.1 and P6-N-4、P6-N-7、P6-N-8 etc.14 hybrids were cluster,show partial male type.

另由树状图得知在L_1处可将55份供试材料分成5大类，除父本4号与母本龙王帽各自成一类外，其余3个父本与杂交苗有规律的聚类在一起，但只有父本1号与P6-N-4、P6-N-7、P6-N-8等14个杂交苗聚类到了一起，表现出偏父型。

The paper supposed that cluster governance has multi- ple governance forms including network governance,market governance and hier- archy governance.Moreover there is"Double Network"consisting of economic network and social network in the organization of industrial cluster,which induce the"Mutual Embeddedness".

In this article made the cluster of phonological type by 4 of main phenophase with bourgeon period, leaf expansion period, flowering period and fruit ripenes period of observed data on phonology of 42 kind of plant 34 year in Minqin desert area, further the 23 of phenology classification merged by phonological type. The 23 of phenology classification basically obeys the ecotype characteristic of the plants, and the more scientific than the type of system cluster by plants sample. Moreover, the form of phonological type record by "ten day period + phonology" in the article.

以民勤荒漠区42种植物34年的物候观测资料，以萌动期、展叶期、开花期和果熟期4个主要物候期进行物候型聚类，进而将物候型归并为23个物候类型，聚合的物候类型基本上遵从植物的生态型特征，较系统聚类法直接用样本聚合的类型更加科学合理。

According to the dendrogram by UPGMA cluster analysis using Neis(1972) distance calculations based on AFLP banding, all the accessions were distinct and revealed enough genetic diversity for identification and classification of accessions within Cajanus cajan. From ME cluster analysis, 9 distinct evolutionary groups were detected. The preliminary results indicated that China maybe one of the pigeonpea genetic diversity minor center.
