将Mie散射理论与蒙特卡罗法相结合分析了含吸收散射粒子半透明介质层的容积吸收特性。

To reduce the absorbing non-homogeneration of the gain medium in a single-end high power pump, a double end-pumped fold cavity structure is applied.

The materiel balance of Nitrogen and Phosphorus in the static examination shows: In eliminating of the nitrogen, Ipomea aquatica absorbing and the artificial medium nitrify contributing up to 31.8% and 38.7%; in eliminating the phosphorus, the contribution that Ipomea aquatica absorbing is 26.7%.

静态运行条件下的氮磷物料衡算显示:在总氮的去除中,空心菜吸收及人工介质反硝化的贡献分别达到了31.8%、38.7%;在总磷的去除中,空心菜吸收的贡献为26.7%。

The full space calculation model, which suits for the asymmetric structure sometimes even including air below the surface of medium, can enable simulative result to approach real one. The FDTD algorithm based on the mixed ABCs is proper to calculate the transmission line where the electromagnetic wave is transmitted in order to send electromagnetic energy along central conductor. The calculation efficiency will be raised if the PML absorbing boundary condition is set on both planes of transmitting direction and so is the MUR two-order absorbing boundary condition in the other planes.

全空间计算模型是适合所有的不对称结构的待研究体的,而且包括了介质下面的空气部分,使仿真更加的接近实验真实情况;基于MUR-PML混合吸收边界条件的时域有限差分法非常适合计算传输线这种结构,因为传输线是传送电磁波的,电磁能量主要是沿着中心导带行进,因此在两个传输端面上设置PML完全匹配层吸收边界条件,在其他面上设置MUR二阶吸收边界条件,会大大提高计算效率,而且计算结果与XFDTD仿真软件计算结果相比较,基本趋于一致。
