Since it's Christmas it seems appropriate that the ageing space camera turns its attention to finding seasonally-shaped nebulas. 圣诞节将至,一把年纪的哈勃望远镜也应该把注意力转向寻找与圣诞有关的星云了。
Galactic nebulas are masses of diffuse material within our galaxy. 银河星云是我们星系中的一团团弥散物。
So magnetism must be dominating the structure of both the nebulas and their dense patches, and therefore it is regulating the starmaking process, the team argues. 研究小组认为,磁力肯定既控制着星云的结构,也控制着其高密度区域的结构,因此可以说磁力控制着恒星的形成过程。
This suggest that the nebulas are aggregates of stars. 这说明星云是恒星的聚集体。
Emission nebulas are clouds of high temperature gas. 辐射星云是一种高温气体云,云中的原子被附近恒星的紫外线激活到高能状态。
Unlike the rapidly rotating neutron stars in the Crab Nebula and Vela supernova remnants that are surrounded by dynamic magnetized clouds of electrons called pulsar wind nebulas, this neutron star is quiet, faint, and so far shows no evidence for pulsed radiation. 与蟹状星云和船帆座超新星遗迹中被磁化电子云(脉冲星风星云)环绕的高速自转中子星不同,这颗中子星安静而虚弱,目前为止,没有显示脉冲辐射的迹象。
It breaks up the uniformity of the nebulas, the hypothesis goes, allowing gravity to pull matter together into clumps and eventually compress them into stars and their planetary systems. 他们的假设为:动荡形势打破了星云分布的一致性,使引力能够把物质吸引到一起形成团状,最终将团状物质压缩成恒星及其行星系统。
The problem with both ideas is that the nebulas are so distant and wispy that they cannot be observed in sufficient detail. 两种观点的问题在于:星云遥远而模糊,无法对其进行特别详尽的观测。
Good spectra of the spiral nebulas are difficult to obtain because of their extreme faintness. 旋涡星云因为非常暗,难以得到它们的清晰的光谱。
Some celestial bodies similar to galactic nebulas but without any luminosity sometimes reveal their presence as dark patches obscuring the light of stars beyond them. 某些与银河星云相似但不发光的天体,有时看来象块黑色补丁,遮住了周围的星光。
The investigation of dark nebulas has been facilitated by a new discovery. 对暗星云的研究被一种新发现所推进。
Players also determine the strength of enemy races and the amount of nebulas which clutter the starfield. 玩家同样也可以决定敌对种族的力量,以及星域中乱七八糟的星云的数量。
Astronomers have argued for years about how stars condense out of the diffuse clouds of dust and gas called nebulas. 由尘埃和气体构成的云团被称为星云。有关恒星如何从呈弥漫状态的星云凝缩而来,天文学家们争论了很多年。
Nebulas need a data definition to receive and description of the data in the process defined. 因为在Nebulas中,需要一个数据定义来接收和描述传递执行流程中的数据,通过该数据定义在Nebulas中实现对科研数据的操作。
The data exchange interface technology in this paper can not only used in Nebulas, the research results can provide a solution for other scientific workflow management system or system call heterogeneous resources of data transfer interface. 本论文中的数据交换接口技术,不仅可以应用与Nubulas中,该研究成果可以为其他科学工作流管理系统或基于异构资源的资封装调用系统中的数据传递接口问题提供一套现有的参考方案。
