摘要：

The authors study reduction of longitudinal ultrasonic oscillations (internal friction Q(-1) and logarithmic decrement.) in NaClO3 crystals within the temperature range of 78 - 525. and relative amplitudes of oscillatory deformation of 10(-7) - 10(-5) according to the method of compound piezoelectric vibrator at the frequencies of approximate to 10(5) Hz. Q(-1) maximums under the temperatures of 110 K, 240 K, 260 K, approximate to 400 K and its fast growth under the temperature over 500 K are revealed as well as athermic peak of. in the region of small deformation amplitudes (near 10(-7)).
