accretion disk造句
例句与造句
- By cutting the gordian knot in this way , astrophysicists have been able to build theoretical models of accretion disks to compare with observations of actual disks
用这方法简化难题，天文物理学家就能够建立吸积盘的理论模型，以便与实际圆盘的观测比较。 - A black hole can accrete matter into itself as the matter falls or is pulled towards it . the accreting material then orbits around the black hole , forming an accretion disk
当任何物体堕进或被吸入黑洞时，都会被黑洞吸积入内，形成黑洞外的吸积盘绕著黑洞运行。 - Such structures , called accretion disks , are also thought to exist around supermassive black holes ( which can weigh as much as a billion suns ) at the centers of galaxies
这种结构称为吸积盘，被认为也存在于星系中心的超大质量黑洞（最重可达10亿倍太阳质量）周遭。 - The efficient conversion of mass into energy by friction in the accretion disk of a black hole seems to be the only explanation for the copious amounts of energy generated by such objects
在黑洞增大圆盘片靠摩擦质量有效转化为能量好像只能解释靠这样的物体产生的大量能量。 - For neutron stars and black holes , accretion disk will emit high - energy x - rays when matters are spiraling in the compact objects , since immense gravitational force can cause substantial heat up of the matters
对于中子星和黑洞来说，大的重力使吸积盘内物质的温度大幅上升，发出能量很高的x射线。 - It's difficult to find accretion disk in a sentence. 用accretion disk造句挺难的
- Hence , for the most part , observations of accretion disks and orbital motions merely indicate that there is a compact object of a certain mass , and says very little about the nature of that object
因此大体上，增大圆盘片和轨道运动的观察只指示有某个质量紧凑的物体,而且有关那个物体的性质说得非常少。 - But when researchers tried to demonstrate this phenomenon using the basic equations of fluid flow and computer simulations , they found no indication that turbulence would develop in an accretion disk
但是当研究人员尝试使用基本的流体方程式和电脑模拟来证实此现象时，并没有发现乱流可在吸积盘中发展的证据。 - Many astrophysicists believe , however , that the most widespread mechanism for friction inside accretion disks is turbulence , which would accelerate the inflow of matter by generating violent , large - scale collisions
然而有许多天文物理学家认为，乱流是吸积盘内最普遍的摩擦机制，藉由大尺度的激烈碰撞而加速物质向内流动。 - It could be that the computer simulations are somehow faulty , but it is also possible that the analogy with pipe flow is simply incorrect and that rotating systems like accretion disks are intrinsically different
可能是电脑模拟错了，但也可能是以管中流体来类推，基本上就不正确，像吸积盘这种旋转系统的性质本就与之不同。 - Candidates for stellar - mass black holes were identified mainly by the presence of accretion disks of the right size and speed , without the irregular flare - ups that are expected from disks around other compact objects
鉴别恒星质量黑洞主要靠合适大小和速度的增大圆盘的存在，没有认为从其它紧密物体周围闪耀的无规律的闪光。 - In the accretion disks in binary systems or at the centers of galaxies , particle collisions would produce an inflow of mass that is too small by many orders of magnitude to produce the brilliant luminosity of these disks
在双星系统或星系中心的吸积盘中，粒子的碰撞只会引起很少的质量向内流动，距离要产生可达到这些圆盘的耀眼亮度，还差了许多个数量级。 - The most conspicuous effects are believed to come from matter falling into a black hole , which ( like water flowing into a drain ) is predicted to collect into an extremely hot and fast - spinning accretion disk around the object before being swallowed by it
相信最显着的作用来自掉入一个黑洞的物质,它(像水流进水沟里)被预言收进一非常热和快速旋转的在被它吞咽之前在物体的周围增大的圆盘片。 - However , accretion disks , jets , and orbiting objects are found not only around black holes , but also around other objects such as neutron stars ; and the dynamics of bodies near these non - black hole attractors is largely similar to the dynamics of bodies around black holes , and is currently a very complex and active field of research involving magnetic fields and plasma physics
然而增大的圆盘片、喷射和绕轨道而运行物体不仅在黑洞周围被发现，但是也在如中子星的其它物体周围被发现；而靠近这些非黑洞引起人注意物体很大程度上类似黑洞周围物体的动力学，而现在是涉及磁场和等离子体物理学研究一个很复杂和活跃的领域。
