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。
