摘要
本文应用线性和三次Hermite插值方法,将管路模型参数公式中Bessel函数在高频域和低频域的两种不同的展开式拟合起来,从而得到便于工程应用的在整个频率范围内连续变化的管路参数近似计算公式.
By means of linear and third-order Hermite interpolation, the model parameter formulas of liquid lines for high-frequency and low-frequency series expansions are combined according to the Bessel function into one approximation for the full frequency range of continuous line parameter variation.lt is accurate enough for engineering application.
