摘　　要：片状体最小悬浮速度可通过传统理论计算和试验获取,因此提出了一种处于压差阻力状态下的片状体最小悬浮速度的计算模型。同时,以甘蔗叶为对象,通过自制的悬浮速度测试装置进行了测试。通过比较发现:传统理论计算的蔗叶最小悬浮速度与实测的最小悬浮速度相差较大,最大相对误差为97.3%,最小相对误差为3 9.4%;而采用本文提供的方法所得的计算结果与实测值的最大相对误差为2 4.9%,最小相对误差为4.7 5%。The minimum suspension velocity of the sheet bodies can be obtained by conventional theoretical calculations and experimental. In the paper, the author provided a computing model of sheet bodies＇ minimum suspension velocity in the pressure drag area. and conducted a verification test in sugarcane leaves through the self-made test device. The re- sult showed that the sugarcane leaves minimal suspension speed by traditional theoretical calculations is large difference with the results of experimental measurements, the maximum relative error was 97.3 % and the minimum relative error is 39.4% ; while the calculation result by this paper is small difference with the results of experimental measurements,the maximum relative error is 24.9% and the minimum relative error is 4.75%.
