摘　　要：分析了反渗透膜元件性能的影响因素及动态特点,给出了反渗透膜元件透水因子与透盐因子的数学模型,明确了两个透过因子多项式模型的参数求解过程与简化计算过程,并提出了反渗透膜元件动态性能参数试验检测的理论与方法。The influencing factors and the features of reverse osmosis （RO） membrane element performance were analyzed. A mathematic model of reverse osmosis membrane element permeability coefficient and salt permeability coefficient was established. The solution and simplified calculation process for the parameters of the two permeability coefficients polynomial model were determined, accordingly detection theory and the method for the dynamic performance parameter of RO membrane element was proposed.
