摘　　要：基于共形完全匹配层(CPML)吸收边界,构造一种共形完全匹配层矢量单元按层积分算法,将多层单元积分运算叠加到一层单元中进行,用多层单元剖分,以一层单元计算矩阵元素,即保留了多层单元的几何和材料信息,又减少了单元数量和计算量.数值算例表明,这种按层积分CPML吸收效果好,计算量小,可靠,高效.We propose a layer-oriented integration arithmetic for conformal perfectly matched layer （CPML）. It reduces number of element and computational scale by superposing multilayer integration to monolayer integration. To retain geometrical and material information of muhilayer elements we mesh CPML by multilayer elements and calculate element matrixes by monolayer integration. Numerical examples show that layer-oriented integration CPML is a reliable and high-efficient absorbing boundary condition.
