| 摘 要： | 本文提出用切仑科夫射电谱线发射机制解释分子云的非热发射谱线。相对论电子在某种粒子数反转布居的分子云中穿行时,可以产生具有反常强度比的微波发射谱线。对与超新星遗迹成协的Ⅱ_(?)类OH源的非热平衡发射谱线所作的计算表明,这种非热辐射机制可能成为解决天体脉塞理论困难的一种有希望的途径。

| Abstract: | The Cerenkov microwave line emission mechanism is suggested to explain the non-thermal emission lines of molecular clouds. Microwave emission lines with anomalous intensity ratio would be produced when the relativistic electrons move through a, molecular cloud with a certain population inversion. The nonthermal emission lines of class IIa OH sources (Physically associated with SNR) are lculated. It is pointed oat that the mechanism of this nonthermal line radiation may be a promising way out of the difficulty in the celestial maser theory. |
