摘要: 采用以阶梯形势垒代替施瓦希-德希特时空中视界附近的势垒的方法,计算了此时空中标量场辐射的反射系数和透射系数。结果表明在此时空中,标量场的反射系数趋于零,而透射系数接近于1,即所有的标量场都将透过势垒而传播到无穷远。

Abstract: The reflection and transmission coefficients of scalar field radiation in Schwarzschid-de Sitter spacetime are calculated, with the method of substituting the potential near the event horizon with a stairs. It is found that the transmission coefficients in this spacetime approaches to 1, this implies that all of the scalar field will propagate to infinity through the horizon.
Key words: Schwarzschid-de Sitter spacetime; scalar field radiation; reflection coefficients; transmission coefficients
