【摘要】 从试验数据采集开始，介绍了用90圆弧进口喷嘴试验装置采集试验数据，根据国际标准进行试验数据的计算，通过风机试验经验公式，对风机的进出口压力、通风机压力、效率等等试验数据进行计算。利用MATLAB对以上的公式进行程序设计，利用MATLAB中的GUI面板，制作了友好的人机交互式界面，从而使这个复杂的计算过程得到大大的简化，加快整个计算过程和提高整个计算过程的精度。更多还原

【Abstract】 The paper introduces that man collects the experimentation data with the quadrant inlet nozzle experimentation equipment. According to the internet standard, through the experience formula of fan experimentation, fan inlet pressure and fan outlet pressure ,fan pressure and the efficiency can be calculated. Making use of the Matlab, man can make the programmer for these formulas. Making use of the GUI panel, man can make the friendly panel, with which human can intercommunicate freely with the computer. So the complicated calculation process make simple.更多还原
