摘　　要：为有效揭示土体在犁体耕作过程中所受的影响,结合压力传感器测试土体内部所受的压力,在流变态粘性土壤中分别布置10个放入隔离盒的压力传感器,然后进行测试。测试的结果表明,该测试手段满足使用要求,与犁体曲率最大位置在同一水平面上的监测点所受水平力最大。传感器测试方法使得机具-土壤的力学关系研究中又充实了一个强有力的实验保障。In order to reveal the relationship between plow and soil, to discuss the feasibility of using the sensors to test the force in the soil, the system that 10 sensors are packaged in the self-isolation boxes is put into the paddy soil for tes-ting. The result shows that the means of testing is feasibility. The data shows that the maximum horizontal force of monito-ring points is on the place which is in the same level with the maximum curvature of plow. The method of testing provides a strong experimental guarantee for researching the mechanic relationship between equipment and soil.
