补充资料:HeⅡ的热机械效应(thermomechanicaleffectofHeⅡ)
HeⅡ的热机械效应(thermomechanicaleffectofHeⅡ)
下图表示了“HeⅡ机械热效应”的逆效应,称HeⅡ的热机械效应。图中表示在液HeⅡ容器B中加进一定热量,致使两边容器中ρs有浓度差,容器A中超流成分经C流进B,又造成Δp的压差和在绝热平衡时的温差ΔT,可用下式表示:
`\frac{\Deltap}{\DeltaT}=\rhoS`
ρ和S分别是HeⅡ的密度和单位质量的熵,乘积ρS是单位体积的熵。上式是1939年首先由伦敦给出,称伦敦定则。若ΔT=1mK,则在T=1.5K时,Δp=2cm液氦柱(压差),所以这个效应是大的。
