中文摘要：
熔融盐是太阳能高温热发电技术中颇具前景的传热蓄热介质．其黏度、密度、比热容和导热系数与熔融盐的传热过程密切相关．利用函数误差理论，从各种传热条件下的经典换热公式出发，分别计算了对传热性能影响＋10％和-10％时各热物性的误差值，并结合热物性数据的误差分析，确定了热物性数据对传热性能计算的影响程度．
英文摘要：
As the heat transfer and storage medium, the molten salts have the good prospect in the high- temperature solar thermal power technology. The viscosity, density, specific heat and thermal conductivity are closely related to the heat transfer process of molten salts. In this paper, the errors of every thermophysical property that causes the heat transfer performance to deviate at ＋ 10% or - 10% were calculated under a variety of classic heat exchange equations, respectively, according to the function error theory. Using the error analysis method, the influence of thermophysical properties data on the heat transfer performance calculation of molten salts was obtained.
