| 摘 要： | 在长输液管线中，如何处理粘性项是目前计算中的难点。本文引入了新的变量，使方程为线性的，同时又具有二阶精度；本文还构造了一个新的插值函数，从而得到计算工作量小、精度高的计算方法。它不仅适用于大摩擦长管，也适用于小摩擦的短管。

| Abstract: | It is more difficult to deal with friction term in numerical analysis of waterhammer in long-range oil transports. In this paper, the new variables were introduced, then the linear equations with second degree of precision have been given out, at the same time also the new interpolation function has been constracted. Finally, we can get the calculation method of analysis of waterhammer in long oil pipeline systems with either less mechan-time or higher precision. It is applied not only to long pipeline with high friction, but also to short pipeline with low friction. |
