Two approaches are applied to outgoing longwave radiation (OLR) data to obtain abnormal changes before and after six earthquakes: the background field analysis (BFA) method, which focuses on statistically processing the increment of a radiation value to the multiyear average of the data; and the tidal force fluctuant analysis method, which abandons background data for many years by using the influence of tidal fluctuations to obtain incremental changes in radiation. The results demonstrate that the increase in OLR data identified via the BFA method was uncertain. In the time distribution, the occurrence time of anomalies is isolated and not continuous. In the spatial distribution, many OLR enhancement areas occurred multiple times in the nonseismic and remote seismic-related fault structure areas. In contrast, through the tidal force fluctuant analysis method a clear and consecutive OLR anomaly emerged in the seismogenic cycle of the tidal force. It corresponded with the tidal force through a unique evolution: increased-earthquake-shrink around the epicentre, consistent with the change in the law of thermal radiation during the rock-breaking process under stress, and clearly related to the earthquake's seismic tectonic stress change. It is proven that the tidal force of a celestial body may trigger an earthquake when the tectonic stress reaches its critical breaking point, and when the triggering action is a continuous rather than brief one-shot process. The in situ stress state is key. The OLR anomaly was the physical performance of underlying surface radiation from the change in seismic tectonic stress.

中强地震外向长波辐射分析

对出射长波辐射（OLR）数据应用两种方法来获取六次地震前后的异常变化：背景场分析（BFA）方法，它侧重于对辐射值对数据多年平均值的增量进行统计处理；潮汐力波动分析法，摒弃多年的背景资料，利用潮汐波动的影响，获得辐射的增量变化。结果表明，通过 BFA 方法识别的 OLR 数据的增加是不确定的。在时间分布上，异常的发生时间是孤立的，不连续的。在空间分布上，许多OLR增强区在非地震和偏远地震相关断层构造区多次出现。相比之下，通过潮汐力波动分析方法，在潮汐力的孕震周期中出现了清晰且连续的OLR异常。它通过独特的演变与潮汐力相对应：震中周围地震收缩增加，符合应力作用下岩石破碎过程中热辐射规律的变化，与地震的地震构造应力变化明显相关。已经证明，当构造应力达到临界断裂点时，天体的潮汐力可能会引发地震，并且触发作用是连续的而不是短暂的一次性过程。这 震中附近震缩增大，符合应力作用下破岩过程中热辐射规律的变化，与地震的地震构造应力变化明显相关。已经证明，当构造应力达到临界断裂点时，天体的潮汐力可能会引发地震，并且触发作用是连续的而不是短暂的一次性过程。这 震中附近震缩增大，符合应力作用下破岩过程中热辐射规律的变化，与地震的地震构造应力变化明显相关。已经证明，当构造应力达到临界断裂点时，天体的潮汐力可能会引发地震，并且触发作用是连续的而不是短暂的一次性过程。这 当触发动作是连续的而不是短暂的一次性过程时。这 当触发动作是连续的而不是短暂的一次性过程时。这原位应力状态是关键。OLR异常是地震构造应力变化对下垫面辐射的物理表现。
