- 論文の詳細を見る
The temperature dependence of the ultrasonic velocities in the temperature range from 15 to $-55$°C was measured for the agarose and methylcellulose hydrogels with different water content. The velocity jump was observed due to the freezing of the free water and it decreased with a decrease in water content. The temperature dependence of the ultrasonic velocities below the velocity jump temperature was discussed.
