摘要
本文将液体导热系数公式一之修改为λ_1=Ar_1^(0.667)(B—T)~n使之成为一个简便,正确且适用范围广的公式。并对25种制冷剂进行了计算,确定了待定常数A和B。计算值与文献值相比,最大误差不超过±5％。
The paper adapts one of the fluid conductivity formulae into λ1 = Ar10.667 (B - T)(n4)making it a aimple,correct and wide-ued formula, we haue also calculated 25 ufrigcrants and determined two undetermined constants A and B. Comparing the calcucating value with documented Value, its error in cithin±5%.
