摘　　要：涉及相对分子质量分布矩的定义及其计算方法,特别是淤浆法高密度聚乙烯链长分布矩的计算方法。在研究了淤浆法乙烯聚合反应机理与动力学的基础上,建立并求解了相应的动力学与矩常微分方程组。所提出的方法已成功地用于工业生产过程。The article deals with the definition of moments of MWD(Molecular Weight Distribution), the method for calculating moment of MWD, and particularly the method for Calculating for moment of MWD of slurry HDPE(High Density Polyethylene). By the research of the ethylene slurry polymerization mechanism and kinetics, the corresponding kinetic and moment ordinary differential equations were built and solved. The method given by the authers is successfully applied in an industrial process.
