摘　　要：用ＳＦ－１型外附力、内聚力测定仪测定了中国南方水田土壤对钢的粘附力。为探讨粘附力与机械组成和含水量的关系，将粘粒含量、含水量和粘附力划分为三个水平，以３３种土样的有关数据为基础导出了土壤的粘附力与粘粒含量和含水量的模糊关系，并提出了一种用模糊推理法预测土壤对钢的粘附力的方法。In order to investigate the relationship among mechanical composition,water content and soilsteel adhesion of paddy soils,numerous data concerning mechanical composition,water content and soilsteel adhesion of paddy soils in South China were collected in ricegrowing season.Based on the related parameters of 33 typical paddy soils,the fuzzy relation of adhesion with clay and water contents was derived,by which paddy soil adhesion to steel surfaces was predicted if soil composition and water content were known.
