| Περίληψη: | A decrease in the strength of cement-sand specimens due to cyclic alternating_sign tem_perature excitation is shown to yield a shift of the principal maximum and the entire spectrum of theelectric response to an impact excitation towards lower frequencies, spectrum broadening, and dete ioration of the spectral maxima quality factor В фонде НТБ ТПУ отсутствует |
