The average range of nonthermal radiation particles is direct proportion to the energy extent of nonthermal radiation particle, but also inverse proportion to the density of stellar gas, however, to the stationary black hole with mass multipole moment and nonstationary black hole, the average range of their nonthermal radiation particle still has something to do with direction, which are the new results reported firstly.
非热辐射粒子的平均射程与非热辐射粒子的能量范围成正比、与星际气体的密度成反比；对动态黑洞和一类具有质量多极矩的稳态黑洞而言，非热辐射粒子的平均射程还与方向有关。这些都是首次报道的新结果。
