高分辨率强运动的预测需要大量的计算资源。将该问题分解为较粗的宏观分析和较细的微观分析相结合的宏微观分析方法，可以有效地减少计算量。然而，困难仍然存在，因为地面或地质结构尚未完全确定。本文提出了一种考虑目标异质体不确定性的宏微观分析公式。借助对一般异质体有效的两个不等式，确定了两个异质体，使它们的响应约束了异质体的期望。
The prediction of the strong motion with higher resolution requires huge amount of computational resources. A macro-micro analysis, which reposes this problem into coupled coarser macro-analysis and finer micro-analysis, is suitable to reduce the required computation. The difficulty, however, remains as the ground or geological structures are not fully determined. This paper proposes a formulation of the macro-micro analysis which accounts for such uncertaninity in the target heterogeneous body. With the aid of the two inequalities which are valid for general heterogeneous bodies, two bodies are determined such that their respones bound the expectation of the heterogeneous body.
