it deals with lots of factors from the process of networks modeling, node demand calculation, initial flow distribution, and the optimal design to the drawing of pipe networks and isopiestic line.
the article includes three parts, which discuss networks 「 optimal design, networks 」 drawing process, and plot methods of isopiestic line respectively.
文章分三部分分别论述了管网的优化计算、管网图形的绘制和等压线图的绘制方法。
in this article is described the arrangement of a set of fairly simple apparatus for the determination of the osmotic coefficient as well as the activity coefficient on the isopiestic principle.
the paper also cites examples to illustrate the popularization and application of the technology of methanol isopiestic synthesis with high-pressure syngas.
