| 摘 要： | 根据对90号无铅汽油和0号柴油进行摩阻实验所取得的实测数据，对紊流混摩区的近似公式进行了误差的计算和比较，并分析了误差产生的主要原因。计算和分析结果表明：科尔布鲁克公式是紊流混摩区的较准确的计算公式，近似公式只适用于粗略的计算和数学分析。

| Abstract: | According to the data which were accquired in the experiment about friction and resistance of 90 # gasoline and 0 # diesel oil,error of approximate formulae in the turbulence mixed friction region was calculated and compared.The reasons for causing errors were analyzed.According to the results of calculation and analysis,Colebrook formula is considered as a accurate formula,and approximate formulae only can be made rough calculation and mathematical analysis. |
