一、前言 集中供热近年来在我国发展很快,管网越来越复杂,管径也有增大趋势,相应的设计计算的工作量也越来越繁重。目前已有不少单位把这些计算工作用计算机来进行,但是使用计算机计算时填表工作繁杂,校对工作所占时间也较长,並且有些管段一次计算不合适时还需重新调整管网后进行第二次填表,再上机计算,这就显得很不方便。要完成这些工作,即使对一个有一定热网设计经验並受过一定计算机知识训练的人来说也要
I. INTRODUCTION Centralized heating has developed rapidly in China in recent years. The pipe network is becoming more and more complex, and the pipe diameter has also increased. The corresponding design and calculation workload has become more and more onerous. At present, many units have used these computers to perform these calculations. However, when using computer calculations, the filling work is complicated and the proofreading work takes a long time, and some pipes need to be re-adjusted after the pipe network is recalculated. The second time to fill in the form, and then calculate on the machine, it seems very inconvenient. To accomplish these tasks, even for a person with a certain degree of thermal design experience and trained in certain computer knowledge,
