摘　　要：明确了反渗透膜元件中以特定给水压为主要特征的产水量、脱盐率及膜压降三项指标与以特定产水量为主要特征的给水压、脱盐率及膜压降三项指标的差异。分析了两类性能指标的相关性与实用性,强调了以特定产水量为主要特征三项指标的独立性能及所具有的技术优势。The difference between performances, which of two type indexes for reverse osmosis （RO） membrane element was indicated. One type index includes permeate flow, rate of desalination and pressure-drop with specified feedwater pressure. Another type index includes feedwater pressure, rate of desalination and pressure-drop with specified permeate flow. The practicality and relativity of the two type indexes was analyzed. The advantages of three independent performance indexes with specified permeate flow was emphasized.
