查询词典 globular

Explanation: M4 is a globular cluster visible in dark skies about one degree west of the bright star Antares in the constellation Scorpius. M4 is perhaps the closest globular cluster at 7000 light years, meaning that we see M4 only as it was 7000 years ago, near the dawn of recorded human history. Although containing hundreds of thousands of stars and spanning over 50 light-years, M4 is one of the smallest and sparsest globular clusters known. A particularly unusual aspect for a globular cluster is M4's central bar of stars.

M4是一个肉眼可见的球状星团，位于天蝎座心宿二的东面约一度位置。M4可能是最靠近我们的球状星团距离约7000光年，这意味着我们看到的是7000年以前的M4，即人类历史有文字记载的开始阶段，它跨越50光年包含有数10万颗恒星。M4是已知在尺度及包含恒星数量上最小的球状星团。M4独特之处是它中心的棒状结构。

Through the study of metallographic specimen and the inclusions through electrolyzation under SEM, it is indicated that the Ti-deoxidized products are globular compound inclusions with the size of 1~3μm in this experiment condition. With the technical of ion beam thinner the inner structure of these inclusions can be observed, whose core is Ti-O and outer is Mn-S. Based on EBSD the phase composition has been analyzed and it indicated that these globular compound inclusions are Ti2O3 and MnS with nucleating center Ti2O3, which can prompt to nucleate IGF.

在扫描电镜下通过对金相试样和电解提取的夹杂物研究表明，本实验条件下钢液凝固过程中析出的夹杂物是Ti-O-Mn-S形成的尺寸为1～3μm的球形复合夹杂物；通过离子减薄后观察了夹杂物的内部结构，中心是Ti-O化合物，外围是Mn-S化合物；通过电子背散射衍射对夹杂物的物相组成的分析表明了该复合夹杂物是有利于针状铁素体形核的Ti2O3和在凝固过程中以Ti2O3为核心形核的MnS。

Like a whirl of shiny flakes sparkling in a snow globe, Hubble catches an instantaneous glimpse of many hundreds of thousands of stars moving about in the globular cluster M13, one of the brightest and best-known globular clusters in the northern sky.

据国外媒体报道，美国宇航局哈勃太空望远镜拍到北部天空中最明亮最有名的球形星团M13，恰似一个天上"雪球"，里面有无数恒星在运动，如同连串的"雪片"在闪烁。

CdtA, CdtB and CdtC form a ternary complex with three interdependent molecular interfaces, characterized by globular, as well as extensive non-globular, interactions.

CdtA， CdtB和CdtC形成一个三聚复合物具有三个独立的分子界面，特征为球状和广泛非球状相互作用。

The method comprises the steps of dipping and mixing the mipor asphaltic base globular active carbon prepared by the traditional method with an inorganic metal salt solution by a certain ration; heating under an inert atmosphere to 600 to 1200 DEG C at a temperature increasing rate of 1 to 20 DEG C/min for the secondary carbonization; using acid to wash off the remaining metal inside the carbonized material, so as to obtain the asphaltic base globular active carbon with a high mesoporous rate and narrow distribution of mesoporous spertures.

本发明提供了一种浸渍金属盐二次炭化制备中孔沥青基球形活性炭的方法，该方法是将传统方法制备得到的微孔沥青基球形活性炭按一定比例与无机金属盐溶液浸渍混合，然后在惰性气氛下以1～20℃/min的升温速率加热到600～1200℃下进行二次炭化，炭化料经酸洗除去内部残留的金属后，可制得中孔率较高、中孔孔径分布窄的沥青基球形活性炭。

In noninfectious uveitis (28.3%), stippled, globular, and multiple globular types of KPs were found.

非感染性葡萄膜炎（28.3%）的角膜后沉着物的特征是斑点状的、球形的以及多球形的。

Of the over 200 globular star clusters that orbit the center of our Milky Way Galaxy, 47 Tucanae is the second brightest globular cluster.

在环绕我们银河系中心的超过200的球状星族中，杜鹃座47的亮度位居第二，仅次于半人马座欧密伽。

Longan1 expressed from the embryogenic callus stage to the globular embryoid stages. Longan2 expressed in the whole process of longan somatic embryogenesis, which was probably a housekeeping gene. Longan3 expressed from the globular embryoid stage to the torpedo-shaped embryoid stage. Longan4、longan4'expressed only at the cotyledonary embryoid stage.

碱基序列分析表明，longan1在3'端存在一个开放阅读框，longan2、longan3分别在5'端存在一个开放阅读框，longan1在3'方向，longan2、longan3在5'方向均没有终止密码子，所以可能往相应的方向延伸仍为各自的ORF，因此可以通过RACE或者筛选cDNA文库的办法来获得它们的全长cDNA。

A suspensor-like structure was formed on the bottom of the proembryo. Along with the constant growth of the proembryo, its shape converted from long-ellipse to obovate, at last it evolved as a globular embryo with smooth surface, and there were absciss layer in the joint of the bottom of suspensor and matrix tissue.

随着原胚不断生长，其形状由长椭圆形发展成倒卵形，最后逐渐形成表面较光滑、外观近球形的球形胚，并在'胚柄'基部与母体组织连接处形成离层。

The determinations of the absolute magnitude and the kinematicparameters of RR Lyrae stars, their effects on the estimations of thedistances and the ages of the globular clusters, and the comparisonsbetween the results and ones from other indicators of distances arereviewed.

对天琴RR型变星绝对星等与运动学参数的测定及其对确定距离、球状星团年龄估计的影响，并对它们和其他距离指示器求得的结果的比较作了评述。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.
