查询词典 globular cluster

Several days before Comet 73P shot across the Ring Nebula,astro-paparazzi Nicolas Outters caught the comet sneaking past M13, the Great Globular cluster in Hercules.

在彗星73P跨越M57前几天，天象摄影家（直译是天文狗仔队——译注）Nicolas Outters 拍下了彗星从球状星团M13附近溜过的图像。M13是位于武仙座的著名球状星团。

Histologically,the activity of cell division in scutellar epithelium and callus cluster derived from it was higher in cultivar Aikoku than Moritawase.Moreover different types of differentiation in the epithelial callus were observed,the rootlike structures and globular cell clusters with epidermislike structure were found in the calli of cultivar Moritawase and Aikoku respectively.

组织学的观察表明，Aikoku的种胚盾片上皮组织以及由上皮细胞起源的愈伤组织的细胞分裂活性高于Moritawase；而且在上述2个品种中还观察到不同的细胞分化类型，在Aikoku的愈伤组织中观察到了带有表皮状结构的圆形细胞块，而在Moritawase的愈伤组织中却观察到了根状结构。

This conclusion was seemingly bolstered in 1999 when Hubble failed to find close-orbiting "hot Jupiter"-type planets around the stars of the globular cluster 47 Tucanae.

这一结论在1999年似乎得到支持，因为当时&哈勃&没能在图坎尼47号球状星团中发现任何紧密围绕恒星运转的类似于&高温木星&的行星。

We report the detection of gamma-ray emissions above 200 megaelectron volts at a significance level of 17sigma from the globular cluster 47 Tucanae, using data obtained with the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope.

根据Fermi伽玛射线空间望远镜的大面积望远镜数据，我们报道对于球状星团47 Tucanae的伽玛射线发射的探测，Fermi的探测结果在200 MeV以上达到17sigma的显著性。

Caption:: Located in the constellation Herculues, M13 is the largest and brightest globular cluster in the northern sky, third in the whole sky, after the Omega Centaurus and 47 Tucanae.

位於武仙座的球状星团M13，是北天球最大最亮的球状星团，在全天排行第三，仅次於南天球的半人马座奥米加星团，杜鹃座47。

Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.

使用标准配件中的K20 目镜，可以得到45倍放大率，这时候很容易看到仙女座星系，还有较小的星系M32；和60毫米口径的折射望远镜相比，114 EQ可以看清更多猎户座星云的细节；瞄准英仙座双星团，看到的星体数量更多，显得更加壮丽；对于球状星团，比如M13，甚至可以显出其中少数独立的恒星；在K20 目镜下（放大45倍）的土星显得相当小，但换成我自己的7.5毫米焦距的目镜(得到120倍)，可以轻松的看到光环在土星上的投影，甚至可以瞥见土星光环内的卡西尼缝隙。

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".

本文在阐释了网络治理内涵的基础上，提出集群治理具有以网络治理为主，市场治理、层级治理为辅的多元治理模式；产业集群组织内部存在经济网络和社会网络，该"双网络"引致"互嵌"机制。

The formation situation of the band for transition metallic carbonyl cluster compounds is analysed with the bond valence formula for atomic cluster compounds.

本文运用原子簇化合物键价计算公式，对过渡金属羰基簇合物成键情况进行了分析，利用金属键轨道数，价非键轨道数和金属配体成键轨道数计算簇合物价轨道总数。

Further, in the cluster set-up phase it uses a novel method for balancing the load of cluster heads.

进一步，在聚类建立阶段它创新地使用了一种聚类首领负载均衡的方法。

More direct, directer ; most direct, directest

径直的，笔直的
