摘要：
The thermomechanical coefficient Delta P/Delta T has been measured for liquid He-3 from 2 - 20 mK. The temperature difference was established across He-3 in a porous plug with 90 nm pore diameter. The coefficient was similar to 5 kPa K-1 and only weakly temperature dependent; in terms of the heat capacity per unit volume, the coefficient varies from similar to 4C at 2 mK to similar to C at 20 mK.
