| 摘 要： | 在规定了选取无标度区和线性拟合的条件之后,对于四川4个主要地震带、中国大陆和四川西部地区,选取不同震级下限,以一定的时间窗和滑动步长,分别计算容量维D0和信息维D1随时间变化的曲线.并对强震前D0和D1值出现下降、先降后升和上升等多种变化特征,以及D0和D1值很接近等现象的可能原因进行了讨论.

| Abstract: | After determination of regularities of choosing non-scaling regions and linear filing, we calculate the curves of the capacity dimension D0 and the information dimension D1 of the seismic temporal distributions with the certain temporal windows and the lengths of sliding steps to the different low limitation of the magnitude for the four main seismic zones of Sichuan province, Chinese continent and Sichuan west area. We discuss various characteristic types of D0 and D1 of the seismic temporal distributions before a moderate or strong earthquake: descending type; raising and then descending type; raising type, and the possible reasons about the fact that the D0 values approximates to the D1 values. |
