摘　　要：应用宁夏银川台和石嘴山台倾斜固体潮观测数据计算了潮汐因子 γ值 ,进一步计算了 γ值的熵值 ,并对各熵值曲线进行分析 ,结果认为 γ值熵在震前的异常表现比较突出 ,熵值变化到最低时 ,很有可能是应变积累到最大程度 ,即进入了临震状态。By using the solid tilt data observed at Yinchuan Station and Shizuishan Station,tide factor γ and the entropy value of γ were calculated.It is found after analyzing entropy value curves that the entropy value of γ shows anomalies before earthquakes.And that entropy value changes to the lowest probably means that strain energy has accumulated to the maximum and an earthquake is impending.
