摘要：The rheological properties of an extrudable material can be measured byextruding a strand of the material, measuring its diameter continuously, to give a seriesof diameter values, interpreting the variations in the strand diameter so as to
characterize the surface of the strand, and deriving rheological data from the surfacecharacteristics of the strand. The variations in the strand diameter can be interpreted asto peak-to-peak amplitude, average diameter value, the frequency of significant extremevalues, standard deviations from a mean value, and the like. By means of these
mathematical characterizations, the rheological behavior of the extrudable material canthen be derived. The scorch behavior of a curable elastomer can be measured. Theheterogeneity of a rubber compound can be described, or the macromolecularproperties of a polymer can be measured (such as \"gel\
