| 摘 要： | 为考虑半透明吸收、散射性介质内各向同性散射对辐射能量传递过程的影响，通过对辐射能量传递过程的分解，提出了一种基于辐射能量传递过程分解的射线踪迹法，该计算方法无需引入预设控制精度参数。经与其他计算方法的比较表明，该新型计算方法正确，计算精度高、计算时间短，可以用于研究介质内辐射能量传递过程的研究。

| Abstract: | To consider influence of isotropic scattering upon transfer process of radiation energy in absorbing-scattering semitransparent medium, a new method based on the decomposition of transfer process of radiation energy was developed. Presettable precision parameter is not introduced in this new method. It shows that the new method is accurate, has high precision, and needs less computational time by compared with the other method, And the new method can be applied to transfer process of radiation energy inside medium. |
