摘要：

We have made a direct measurement of the thermal expansion of liquid3He between 1 and 200 mK at saturated vapour pressure, by measuring the change in volume as a function of temperature with a coaxial capacitive level detector. Our results do not depend on calibrations against known liquids, nor require any other data as input. We find good agreement with other, less direct methods.
