A systematic study is carried out on K{sub 0.3}MoO{sub 3} crystals irradiated with 2.5-MeV electrons. The high-temperature charge-density-wave (CDW) threshold field {ital E}{sub {ital T}} and the static dielectric constant {epsilon}({omega}{r arrow}0) are measured in the temperature range 40{lt}{ital T}{lt}70 K, and the low-temperature CDW depinning field {ital E}{sub {ital T}}{sup *} and the dielectric constant {epsilon}{sup *} at liquid-helium temperature (4.2 K) are also measured, all as functions of increasing irradiation dosage. Empirical relations among these quantities, which characterize the dynamics of charge-density waves in both the high-temperature and the low-temperature regimes, are established. Our experimental results are then compared with current theoretical models.
