By means of the Dirac equation and the generalized Tortoise coordinate variation, the event horizon equation and Hawking temperature of the black hole are obtained directly, and finally the Hawking radiation formula of the Dirac particles is educed.

• 从Dirac四分量方程出发 ；经广义Tortoise坐标变换 ；直接导出黑洞的事件视界面方程及温度函数 ；并最终获得了Dirac粒子的热谱公式 .
