本文提出了银河系的烟囱模型，并解释了它的基本物理原理。该模型的关键点是，银河系盘和晕是由烟囱连接，这是一个后果的超级气泡爆裂出磁盘形成这些准直结构，通过全球质量和能量交换流从磁盘到晕。对于典型的银河系参数，烟囱阶段被发现与0.3-3太阳质量/年的质量流率和10的40次方至10的42次方尔格/秒的全球功率输入。参考文献72篇。
A chimney model for the Galaxy is presented and its underlying physical principles are explained. The crucial point of the model is that the Galactic disk and halo are connected by chimneys which are a consequence of superbubbles bursting out of the disk forming these collimated structures through which the global mass and energy exchange flows from disk to halo. For canonical Galaxy parameters, the chimney phase is found to be associated with a mass flow rate of 0.3-3 solar masses/yr and a global power input of 10 to the 40th to 10 to the 42nd ergs/s. 72 refs.
