摘　　要：本文由动量、能量守恒定律,简便地推导出静态电磁场的动量密度表达式.与通常做法不同,推导过程未涉及麦克斯韦方程组.In this article the formulation of the momentum density in the static electromagnetic field was simply deduced by employing the conservation laws of the moment and energy. This procedure was different from the usual way in which the Maxwell Equations were concerned.
