摘要：

Ambiguities in extracting a value for the superlocalization exponent from variable-range conductivity data of fractal systems are pointed out. In particular it is shown that by allowing for a pre-exponential temperature-dependent factor, recent data taken on carbon-black-polymer composites may support percolation as well as non-percolation exponents.
