星际介质动力学分子外向流喷流恒星形成 |
| 2. | Molecular outflows mark an important phase in the early evolution of star formation
分子外流标志着恒星形成早期演化的一个重要阶段。 |
| 3. | Because of the connection between outflow and accretion seen in low - mass stars , surveys of molecular outflows in high - mass ysos can shed light on this debate
因为在低质量恒星形成中外流与吸积相联系，在大质量恒星形成区搜寻分子外流将有助于解决这种争论。 |
| 4. | Uc h ii regions and are undergoing outflowing motions , which might be produced either by the expansion of the recently formed h ii region or by the presence of molecular outflows
这种运动可能由新形成的hii区膨胀形成或者由已经存在的分子外流驱动。我们对ngc7538irs1的氨分子vla观测数据重新进行了处理，分析了其动力学结构。 |
| 5. | Molecular outflows from young stars are important phenomena in star formation suggestions for their driving mechanisms are various . several jet - driven models are introduced . according to the domination of two interaction patterns , models are classified as two kinds , and a detailed introduction of each kind are presented . flnally , some left problems are forwarded
按喷流与周围介质的相互作用过程把外向流的喷流驱动模型分为2大类，对其中几个作了较为细致的分析和比较，最后提出了今后模型发展的方向。 |
| 6. | There are two different ideas about the massive star formation . some investigators suggest that high - mass stars form via dynamical collapse of cloud cores , resulting in disk accretion and molecular outflows , similar to their low - mass counterparts ; some peoples suggest that high - mass stars form by the coalescence of low - to intermediate - mass stars
关于大质量恒星的形成有两种观点：一种观点认为大质量恒星通过云核的塌缩，然后产生一个吸积盘和外流，即相似于低质量恒星的形成；另一种观点认为大质量恒星通过中小质量的恒星并合而成。 |
