本文用固体潮高时段地震（调制小震）活动性图象演化过程，综合判定小震调制比Ｒｍ的异常值，提高Ｒｍ凡异常在中短预报地震的效能，并对小震调制比地震预报方法资料区域选择问题进行了一些探讨，提出区域过小或不适当的区域选择都可能产生不合理的Ｒｍ异常．在对辽宁及邻近地区５级左右地震短临预报指标的研究中，显示出用固体潮高时段地震形成的强震前空区活动图象比用全部地震形成空区图象特征更加明显的特征．
In this paper, we use the moving image evolution process of earthquakes (modulated small earthquakes) during solid tidal period to synthetically determine the anomalous values of small earthquakes (Rm), and improve the performance of Rm anomalies in short and medium earthquakes. Method data area selection, some suggestions are put forward that it is suggested that an unreasonable Rm anomaly may be generated if the area is too small or inappropriate. In the study of short-term and short-term prediction index about 5 earthquakes in Liaoning and its adjacent areas, it is shown that the moving images of the strong earthquakes formed by the earthquakes with solid tides are more obvious than the features of all the images of the earthquakes forming empty areas .
