1前言在过去几年里，冰箱和空调等制冷行业在将使用原有制冷剂CFC－12的制冷系统转化成使用新制冷剂HFC－134a的制冷系统方面已取得很大的进展。在该系统转化过程中，大量的研究集中于配套结构材料和润滑油的开发和选择方面，而取得结构材料与润滑油的兼容性数据是选择结构材料
1 Introduction In the past few years, refrigeration industries such as refrigerators and air conditioners have made great strides in converting refrigeration systems that use the original refrigerant CFC-12 to refrigeration systems that use the new refrigerant HFC-134a. In the process of system transformation, a great deal of research has been focused on the development and selection of supporting structural materials and lubricants. The compatibility data of structural materials and lubricants are obtained by selecting structural materials
