摘要：
A method of measurement of relaxation phenomena, in which input signals representing a relaxation phenomenon are recorded at equal intervals for logarithmic values of time.A measuring device for relaxation phenomena which comprises a logarithmic time pulse oscillator for producing pulse signals at equal intervals for logarithmic values of time, and a recorder for recording input signals representing a relaxation phenomenon converted into an electrical quantity, which operates to perform recording each time a pulse signal is produced.
