摘　　要：作者通过哈密顿-雅克比方程,在新乌龟坐标变换下,研究了Dilaton-Maxwell黑洞时空中的非热辐射特征,获得粒子能量所在的禁区宽度,以及出射粒子的最大能量.同时,根据方法我们还得出了该黑洞时空视界处的表面引力.According to the Hamiltonian Jacques-than equation, in a new general Tortiose coordinates, this paper discussed non-thermal radiation characteristics in Dilaton-Maxwell black hole space-time, the width of particle energy level and the biggest energy of outgoing particle are obtained. Meanwhile, it gained the surface gravity of the Dilaton-Maxwell black hole at the event horizon.
