光子在介质中的传输及其相互作用的物理过程最好是在经典电磁波理论的基础上描述的，即麦克斯韦方程[Ishamaru，1978~，B]。如果认为相位信息不重要，则可以考虑介质中光子的命运、迁移和相互作用，而不是电磁场。这导致了描述辐射及其传输的粒子性质的辐射传输理论[Jumrasekhar，1960;中性粒子输运问题已经被天体物理学、大气物理学、生物学、工程设计、激光束传播和相互作用、冶金学、核工程、遥感、输运理论在诸如行星和地球大气中、植物和水介质中散射强度的计算、燃烧室和燃煤炉中的热分布以及用于临界计算和屏蔽目的的核反应堆中和周围的中子和伽马射线的分布等情况下具有广泛的应用。中性粒子输运的一般理论可以在Davison（1958）、Sirrasekhar（1960）、Sobolev（1975）、Duderstadt和Martin（1979）以及货车de胡尔斯特（1980）的经典著作中找到。
The physics of photon transport and its interaction in a medium is best described on the basis o 4 classical electromagnetic wave theory, viz. Maxwell equations [Ishamaru, 1978~, b]. If phase information is deemed unimportant, then fates, migrations and interactions of photons in the medium may be considered instead of electromagnetic fields. This results in the theory of radiative transfer that describes the particle nature of radiation and its transport [Chandrasekhar, 1960; Sobolev, 1975].The problem of neutral particle transport has been extensively pursued by investigators in such diverse disciplines as Astrophysics, Atmospheric Physics, Biology, Engineering Design, Laser Beam Propagation and Interactions, Metallurgy, Nuclear Engineering, Remote Sensing, etc. Transport theory has a wide range of applications in cases such as computation of scattered intensities in planetary and terrestrial atmospheres, in vegetative and aquatic media, distribution of heat in combustion chambers and coal-fired furnaces, and in distribution of neutrons and gamma rays in and around nuclear reactors for criticality calculations and shielding purposes. The generic theory of neutral particle transport can be found in the classical works of Davison (1958), Chandrasekhar (1960), Sobolev (1975), Duderstadt and Martin (1979) and Van de Hulst (1980).
