我们清楚地描述了在不知道复合材料的几何信息但有一组测量的输运性质的情况下，弥尔顿关于复合材料标量输运性质的界限。当测量值受到已知误差的影响时，我们考虑如何使用它们。在这种情况下，使用了统计分析。我们通过考虑涉及二维和三维复合材料的六种情况来说明这种分析可能产生的各种结论。在六种情况中的四种情况下，得到了与已知值一致的复合材料体积分数的估计值。在第五种情况下，分析指出了实验数据中可能存在的错误，而在第六种情况下，由于粒子之间的丝状连接，它揭示了输运性质对复合几何形状的关键依赖。
We describe clearly Milton's bounds on the scalar transport properties of composite materials in the case when no geometrical information is known about the composite, but when a set of measured values of a transport property is available. We consider how the measured values may be used when they are subject to known errors. In this case, a statistical analysis is employed. We illustrate the various conclusions which may result from this analysis by considering six cases involving both two-and three-dimensional composites. In four of the six cases, estimates of the volume fraction of the composite in agreement with the known value are obtained. In the fifth case, the analysis pointed out a possible error in the experimental data, while in the sixth it revealed a critical dependence of transport properties on composite geometry due to filamentary linking between particles.
