摘要

在16 ~ 55°C范围内测量了液体壬酸(pelargonic)中的超声波衰减。在16°C和25°C的超声波范围内，发现了单一的弛豫现象。在35、45和55℃时，两种弛豫现象明显。这两种现象中的一种在溶液状态下消失。

Ultrasonic relaxation in liquid nonanoic acid. The variation of the ultrasonic spectrum with temperature

The ultrasonic attenuation in liquid nonanoic acid (pelargonic) is measured between 16 and 55°C. A single relaxation phenomenon is pointed out at 16 and 25°C, in the ultrasonic range. At 35, 45 and 55°C, two relaxation phenomena are evident. One of the two phenomena disappears in the solution state.
