摘　　要：利用通风性能参数检测装置研究吸出式和压入式两种通风方式下玉米粮堆阻力特性相关参数的变化情况,试验结果表明:粮面表观风速与单位粮层阻力、穿网阻力呈正相关,且多项式二次函数拟合度较高。玉米粮堆的通风均匀度与粮层厚度呈正相关,粮层越厚,均匀度越高。The changes of resistance characteristics in corn under suction and push-in ventilation modes were studied by the testing device of ventilation performance parameter,the results showed that the surface wind speed of grain was positively correlated with the resistance of unit grain layer and the resistance of net,and the polynomial quadratic function has higher fitting degree.The ventilation uniformity of corn is positively correlated with the grain layer thickness.The thicker the grain layer,the better ventilation uniformity.
