摘　　要：通过对CF/S-157PF复合材料进行氧-乙炔烧蚀试验研究,得到了质量烧蚀率,并利用多元线性回归方法,拟合得到了该参数与热流密度和烧蚀时间的数学模型,即M=0.043.q0.128.t-0.191。经检验,该回归模型适用性较好,预测精度较高,为复合材料该项烧蚀性能的评估建立了快速、有效、可靠的试验方法。In this paper,the important characteristic parameter,namely the mass loss rate,was obtained by the investigating on CF/S-157PF composite under oxyacetylene flame test conditions.And using multiple linear regression,the mathematic model on the mass loss rate and the two major factors,namely the heat flux density and ablation time is as follows：M=0.043·q0.128·t-0.191.It is verified that,the regression model is very applicable and the forecast accuracy is much better.So the erosion properties of CF/S-157PF composite can be evaluated with this rapid,effective and accurate method in the oxyacetylene flame test.
