1. How a star creates Herbig-Haro jets is an ongoing topic of research, but it likely involves an accretion disk swirling around a central star.
恒星如何创造赫比格-阿罗喷流，是一个正在进行的研究课题，但它可能涉及围绕中央恒星旋转的一个吸积盘。
2. They zapped a tiny plastic pellet with 12 laser beams fired simultaneously and allowed some of the resulting radiation to blast a pellet of silicon, a common element in accretion disks.
他们利用12道激光束同时袭击一个小小的塑料球，再利用所形成的部分辐射引爆一个硅球，而硅是吸积盘中的一种常见元素。
3. The emission from thiscomponent of the accretion disk should therefore be stretched, or redshifted, providing astronomers with a means of quantifying how fast the black hole isspinning.
这个来自吸积盘的成分的发射物的应该因此被拉伸，或被称为红移，为天文学家提供一个量化的手段来测量黑洞旋转得有多快。
4. The energy release can make accretion disks formidable power sources.
此能量释放使吸积盘成为巨大能量的来源。
The moon was formed through the process of accretion, gathering dust and debris over millions of years.
月球是通过积聚尘埃和碎片的过程形成的，历经数百万年。
In astronomy, stars can grow larger by accreting mass from surrounding gas clouds.
