The effective thermal resistance and the effective coefficient of heat transfer during the formation of fouling are defined. 提出了污垢形成过程有效热阻与有效总传热系数的概念。
When the bath temperature was close to the temperature, more experimental and theoretical work should be done because the thermal resistance of superfluid helium increased a lot. 而在点温度附近，由于超流氦热阻大幅度增加，仍需更深入的理论研究与实验。
