摘要：

By measuring the complex dielectric susceptibility over 15 decades in frequency we compare the alpha-relaxation in low-molecular-weight glass-forming liquids and polymers. To describe the scaling behavior of the a relaxation, a minimal set of four parameters is necessary, the mean relaxation time, the dielectric strength, and two shape parameters, describing the low- and high-frequency wings of the relaxation function, in pronounced contrast to a recently published scaling function.
