The relationship between the master Stribeck curves of the polymer aqueous solutions and the influence factors were investigated. Experimental results indicated that soft lubrication is determined by lubricant rheological properties and surface-lubricant interactions, e.g., wetting behavior of polymer aqueous solution on tribological surfaces. 关键词：SOFT contact LUBRICATION LINEAR polymer AQUEOUS solutions MIXED LUBRICATION BOUNDARY LUBRICATION
