摘要
本文应用Ｂａｓｉｃ语言设计计算沿程阻力损失的程序，结果计算准确且迅速，克服了复杂而烦琐的手工计算，既保证了工程上的技术要求，又可减少工程材料上的浪费．
This thesis deals with the design of a program for calculating the loss of resistance along the project, the speed is faster and more accurate than compresive mannual calculation.This not only fulfilledtechnical requirements,but reduced the waste of project material.
