论文摘要
雷暴大规模电场加速的相对论失控电子雪崩（RREA）是大气伽马辐射的来源之一。在强大的电场中，RREA可以乘以相对论的反馈。无限的相对论反馈使雪崩可自我维持，并假设地导致地面伽马射线闪光灯（TGF）。本文介绍了一种动力学方法来研究由正上子引起的相对论反馈，因为正电子反馈主导了直接观察到的电场强度。通过这种方法，得出了雷暴内无限正电子反馈的标准。发现的标准允许获得任何高度的无限正电子反馈所需的雷暴电场参数。讨论了雷暴条件的可能性。
Relativistic runaway electron avalanches (RREA) accelerated by thunderstorm large-scale electric fields are one of the sources of atmospheric gamma radiation. In strong electric fields, RREAs can multiply by the relativistic feedback. Infinite relativistic feedback makes avalanches self-sustainable and hypothetically can cause a terrestrial gamma-ray flash (TGF). This paper introduces a kinetic approach to study the relativistic feedback caused by positrons since positron feedback dominates for the directly observed electric field strengths. With this approach, the criterion for infinite positron feedback within thunderstorms is derived. Discovered criterion allows obtaining the thunderstorm electric field parameters required for infinite positron feedback for any altitude. The possibility of derived thunderstorm conditions is discussed.
