本文中DRESOR法(Distributions of Ratios of Energy Scattered Or Reflected)应用于求解一维非均匀介质内的瞬态辐射传输问题。结果表明,反射热流的双峰分布现象能够体现介质内部的非均匀分布特征,并且能够通过分析其特点推断非均匀介质的中间界面位置.通过DRSESOR法计算得到的高方向分辨率的辐射强度体现了其在决定非均匀介质表面位置的独特优势.最后,对双峰分布现象的存在条件进行了探讨.
In this paper, the DRESOR method (Distributions of Ratios of Energy Scattered Or Reflected) applied to solve one-dimensional inhomogeneous medium transient radiation transmission problems. The results show that the bimodal distribution of reflected heat flow can reflect the non-uniform distribution of the medium, and the inhomogeneous medium can be inferred by analyzing the characteristics of the intermediate interface.The DRSESOR method calculates the radiation intensity of the high-resolution directional radiation Its unique advantages in determining the location of the surface of inhomogeneous media.Finally, the existence of bimodal distribution is discussed.
