【摘要】 目前,多口出流管道的水力学设计方法有数解和图解两大类,其中数解法精度较高,但不直观;图解法则简捷、直观,但一定程度上精度较低。操作仍有不便之处。本文针对世界上沿用较广的Polyplot多元图解法,应用解析几何和计算机卡通法相结合,提出一种在IBM—PC/XT上实现的微机图解法,该法是对以往图解法的一种改进,能保持直观,而操作更为简便、精度更高。更多还原

【Abstract】 At presend, there are two categories of method for multi-outlet discharge hydraulic design: numerical solution and graphical solution. The former is more accurate but less perceivable, and the latter is low in accuracy but simple and directly preceivable. Neverthless, it is not guite easy to operate. This paper adopts both analytical geometry and computer animation methods to make a popular nomogram manual called ’polyplot’ and proposed a graphical solution with the computer IBM-PC/XT. In comparision with manual method, the new method is an improvement, andit is diretly perceivable, more simple, convenient and accurate.更多还原
