| 摘 要： | 考虑到相对论效应，采用量子统计的方法，得到了满足Bose-Einstein统计分布和Fermi-Dirac统计分布的两类粒子的黑体辐射公式（包括Planck黑体辐射公式）．发现辐射谱不仅与黑体的辐射温度有关，还与辐射粒子的能量、化学势和种类有关．辐射强度与辐射粒子的能量、静质量、简并因子有关。

| Abstract: | Considering relativistic effect, by using quantum statistics, the radiation formulas of two types of particles, consisting of Planck black-body radiation formula, are obtained, which satisfy Bose-Einstein statistics and Fermi-Dirac statistics respectively. It is found that the radiation spectrum is not only relative to the radiation temperature of black-body, but also to the energy and the chemical potential and the kinds of particles, The radiation strength is relative to the rest mass and the energy of particles, and the degeneration factor. |
