本文从相对地应力测量观测值函数X(t)中动态基线带X°(t)的力学机理出发,论述了X(t)数学分解的可能性和对X°(t)的数学模式进行反算的方法,分析了用预测X°(t)来离析X(t)中震前致震应力异常信息X_3°(t)的可能性。实际资料计算与分析表明:直接预测X(t)中X°(t)的变异,是较为可靠地间接提取震前应力异常信息的有效途径。
Based on the mechanics of the dynamic baseline X (t) in the X (t) function of relative stress measurement, the paper discusses the possibility of mathematical decomposition of X (t) and the mathematical model of X ° (t) This paper analyzes the possibility of using the predicted X ° (t) to separate the information of pre-earthquake onset stress anomalies X_3 ° (t) in X (t). The calculation and analysis of the actual data show that directly predicting the variation of X ° (t) in X (t) is an effective way to extract the information of pre-earthquake stress anomaly more reliably.
