摘　　要：热水供暖异程系统可采用等温降法进行水力计算。传统手算计算方法因为计算过程较为繁琐,往往难以被学生熟练掌握,达不到较好的运用效果。文章通过计算实例说明,用自编电子表格的方法,可以很好地辅助水力计算,并给出了表的编写方法和计算顺序。Constant temperature drop method can be used for hydraulic calculation of hot water heating system. Because the traditional manual calculation method is cumbersome, it is often difficult for students to master it skillfully, and can not achieve good application effect. Through calculation examples, this paper shows that the method of self-made spreadsheet can well assist hydraulic calculation, and gives the compilation method and calculation order of the table.The practice shows that the new method has strong operability, which can be used in both teaching and engineering practice, and has strong application value.
