| 1. | This formation, called an accretion disk, may be very important in some stellar birth sequences .
这种构成物即所谓吸积盘，它在恒星诞生的某些阶段可能是非常重要的。 |
| 2. | As the accretion disk feeds more mass into itself, the embryo star contracts, growing ever denser and more massive .
随着吸积盘获得越来越多的物质，胚胎恒星就不断收缩，密度和质量都变得越来越大。 |
| 3. | Direct observation of these protoplanetary disks were made only a few years ago
我们在数年前才发现到这些原恒星的吸积盘。 |
| 4. | Accretion disks and jets
吸积盘和喷流 |
| 5. | Concept image of a supermassive black hole with an accretion disk , an outer dust torus
构想的巨型黑洞拥有吸积盘，对外是尘埃环， |
| 6. | Usually , a real black hole will have accretion disk around it and have jets gushing out at two poles
通常，黑洞会被吸积盘所环绕，两极更有喷流。 |
| 7. | But what is the nature of the friction inside the accretion disks that touches off this enormous energy release
然而，引发吸积盘内巨大能量释放的摩擦，本质是什麽？ |
| 8. | But why microlensing , which essentially is an object being occulted , causes the occulted object to brighten
为什么黑洞会被吸积盘所环绕？为什么黑洞又会有x射线射出？ |
| 9. | Nevertheless , astrophysicists have persisted in their belief that accretion disks are indeed turbulent
虽然如此，天文物理学家仍旧坚持信念，认为吸积盘的确是充满乱流扰动的。 |
| 10. | And astronomers , in fact , have seen evidence of spiral - wave patterns in accretion disks in some binary systems
事实上天文学家已在一些双星系统的吸积盘中，看见螺旋波图样的证据。 |
