摘要
作者用数理统计方法求出了尼库拉则-卡门方程的近似求解公式.用新的近似式计算光滑管摩擦系数比原公式简单.在整个公式适用范围内,近似式与原式计算值之间的最大相对误差的绝对值不超过0.7%.
An approximate solution to Nikuradse-Karman ,s equation is found by means of mathemati-cal statistics.It is more simple than the old one,and the absolute value of the maximum of relative er-ror is less than0.7%throughout the using of the equation.
