摘　　要：对圆柱形室和丝室中的自猝灭流光作了实验研究,提出另一有关其形成机制的解释。在潜迹和相继的雪崩中产生的激发态原子或分子起着非常重要的作用,是主要的光电子源,而其相互作用也可能是电离光子源。文中给出描述跳变和流光电荷的公式,同时采用计算机程序动态地考虑空间电荷电场效应。理论和实验进行了比较。Experiments on self quenching streamer discharge in cylindrical tube and wire chamber are performed, and an interpretation of SQS mechanism is proposed in this paper. The excited·atoms or molecules created in the latent track and subsequent avalanche play an important role, they form the main photo-electron source and the interaction between them is also possibly a source of ionizing photon. A formula that describe the jump and streamer charge is deduced. The effect of electric field of the space charge is computed. The comparison between theory and experiments is made.
