摘要
提出了一个新的对数均值表达式:x_m=((x_1^(1/3)+x_2^(1/3))/2)~3不仅计算准确度高,而且可直接进行解析求解,避免了迭代计算。该式可用于传热,传质过程中的均值计算,代替原来的对数均值计算式。
A new expression for logistic mean was developed and written as It not only has high accuracy, but also can be directly solved by the analytical method. The expression can be used to calculate the mean in the heat transfer and mass transfer processes to replace the original calculation expression.
