摘　　要：燃速与辐射通量之间的关系可以由两支相交直线构成的线性方程进行描述,其中折点(交点)是外界辐射能作用下固体双基推进剂燃烧的一个重要特征。包括折点附近在内的燃烧特性可以采用Fourier方程进行分析。考虑到辐射在燃烧表面上形成的碳化层对辐射传递的阻碍作用,本文分析了1040,1041,N-5和N型推进剂的燃烧特性。导致两段函数和折点形成的主要原因是在辐射能到达凝聚相表面之前部分辐射能已经发生了损失。A piece - wise function in the dependence of burning rate on the radiant flux and its break point are important characteristics of burning of double base propellants under external irradiation. Using Fourier equation can analyze the burning characteristics, including characteristics near the break point. Considering the shielding effects of carbonous layer forming on the burning surface on the transmission of external irradiation, the burning characteristics of 1040, 1041, N -5 and N propellants were analyzed. One of main reason induced a piece - wise function and the break point is the loss of radiant energy before the radiant energy reaches the surface of condensed phase.
