| 摘 要： | 本文在全部入射角范围内系统地讨论了时域局部透射边界真实的反射系数及其与理想稳态和理想暂态反射系数的关系。文中指出，后两者可分别用作前者上，下限的估计；同时，就时域逐步积分计算而言理想暂态较之理想稳态更接近真实情形，简便的理想暂态反射系数可用于在全部入射角范围内度量边界是的误差。

| Abstract: | In this paper the authors systematically discuss the realistic reflection cnefficient of local transttnitting boundary and its relationship to coelfficient in ideal steady -state and ideal t.ansient -state in the all angles of incidence. It is pnint out that the upper limit and lower limit of the former are decided by the latter nnes. For the step - by - step numerical integralinn, the ideal transient - slate is more closely to the realistic case than the ideal steady - state, and the simplified reflection coefficient of transient - state is useful to eval- uate the errnr nf artificial boundary in the all angles of incidence. |
