一系列的实验已经完成，以测量液体和固体3 He之间的温度1和25 mK的熔化曲线密度的热性质。用Pomeranchuk方法对~ 3 He样品的两相混合物进行了自冷实验。使用热脉冲技术，结合压力和体积的测量，产生液体和固体性质的单独测定：在正常费米液体和超流相中的液体3 He的比热;固体3 He的熵以上，并通过在1.10 mK的核磁转变;和绝对热力学温标的基础上测量的潜热转换的液体到固体。
A sequence of experiments has been performed to measure thermal properties of liquid and solid 3He between the temperatures 1 and 25 mK at melting curve densities. A two-phase mixture of 3He sample was self-cooled by the Pomeranchuk method. A heat pulse technique was used, combined with measurements of pressure and volume, to yield separate determinations of liquid and solid properties: the specific heat of liquid 3He in the normal Fermi liquid and superfluid phases; the entropy of solid 3He above and through a nuclear magnetic transition at 1.10 mK; and an absolute thermodynamic temperature scale based on measurement of latent heat of conversion of liquid to solid.
