本文主要说明在喷管实验台上,应用微型计算机进行数据采集和处理的方法。在程序控制下,可以计算、显示、打印数据和实验曲线。文中给出了喷管实验台本体和测试系统图以及实验的程序框图和实验结果。把微机用于喷管的性能测试,扩大了原喷管实验台的功能,而且更加准确迅速、机动灵活。 This paper mainly describes the method of data collection and processing by using a microcomputer in a nozzle test bench. Under the program control, you can calculate, display, print data and experimental curves. In this paper, the spray nozzle test bench body and test system diagram and the experimental block diagram and experimental results. The computer used for nozzle performance testing, expanding the original nozzle test bed functions, but also more accurate and rapid, flexible and flexible.
