摘要：

The electrical conductivity ( sigma ), the thermal conductivity ( lambda ), the permeability ( mu ) and the Young's modulus (Y) are given as functions of the volume fractions for a series of sintered nickel samples. It is shown that sigma , lambda and mu data can all be fitted to a single equation with the same two morphology parameters f//c (a critical volume fraction) and t (an exponent) and separate bulk values of sigma //N//i, lambda //N//i and mu //N//i. The Y data is fitted with the same value of f//c but a different t.
