摘要
为了进一步考察潜在震源区勾画的不确定性,本文提出了“复合潜源”的概念。通过复合潜源参与系数的引入,最终导出的多维复合离散概率的表达式,在前文(Ⅰ)的基础上得到了自然的拓广。适当选取复合潜源的源权、叶权与置信度,可以使潜在震源的物理与几何参数二者作为整体的不确定性,在统一的概率模型中一次处理。 最后,本文给出了两个典型算例。分析表明,潜在震源不确定性的复合概率贡献,与假想的确定潜源结果之间,具有良好的一致性。
In order to further take into account uncertainty of potential source zones,a concept of 'complex source' is proposed in this part. The representation of participating coefficient results in the multiple dimension probabilistic expression which is a normal extension in the case of the certain source zones in the part( I ). Based on the selection of suitable source weights, leave weights and confidence, the uncertainty of both the physical and geometrical parameters of source zones can be treated in just one probabilistic expression at the same time.Finally,two typical examples are given. The analysis shows that the complex probabilities when modering the uncertainty of source zones are consistent,in a certain degree,with imaginary 'true location'.
