Mass-accretion 林积生长
For a stationary, adiabatic flow the specific energy E, specific angular momentum L and mass accretion rate M are constant in space.
对于静态、绝热吸积流，比能量E、比角动量L和质量吸积率M都是空间的常量。
Therefore, it is an absolutely necessary key to understand the process of mass accretion for interpretation of the particular high-energy radiation from these systems.
所以了解吸积过程是解释这些天体独特的高能辐射特性的一把必不可少的钥匙。
"The only remaining doubt," he said, "is whether massive stars of much higher mass, say 50 or 100 [solar masses], will form by the same accretion process."
唯一剩下的疑问是“，他说，”更大的星体，如50 - 100个太阳大小，是否也通过同样的积累方式形成的。
