初步翻译了一下，“平差”不会
the task of this program is to use the existing price and the parameter adapting to the current reality of urban water supply to calculate the economic flow rates with different kinds of pipe material and different sizes of pipe diameter, and carry out technical economic calculation using the method of pipe net technical economic calculation combineing the actual net works.
Keyword: Unit cost, economic factor , limited rate of flow
