L(tau)
symbol, see observation
OBS

The "spectrum of relaxation times," "H(tau)," determines the time and frequency dependence of the macroscopic moduli and is measured in pascals (Pa). The "spectrum of retardation times," "L(tau)," determines the time and frequency dependence of the macroscopic compliance and is measured using the reciprocal of the pascal (Pa-1).

OBS

L(tau): The term "tau" must be replaced by the corresponding Greek letter.

OBS

spectrum of retardation times: term and symbol recommended by the International Union of Pure and Applied Chemistry (IUPAC) and standardized by the International Organization for Standardization (ISO).

Key term(s)

OBS

Le «spectre des temps de relaxation», «H(tau)», détermine la dépendance des modules macroscopiques du temps et de la fréquence, et se mesure en pascals (Pa). Le «spectre des temps de retardement», «L(tau)», détermine la dépendance des complaisances macroscopiques du temps et de la fréquence, et se mesure au moyen du réciproque du pascal (Pa-1).

OBS

L(tau) : Le terme «tau» doit être remplacé par la lettre grecque correspondante.
