Guangtongxin yanjiu, 2008 文章以亥姆赫兹方程为基础,推导了三维有限差分光束传输法（FD-BPM）,并在阵列波导光栅模拟计算中采用该方法对光场在阵列波导中的传输过程进行了计算和模拟。结果表明,采用三维FD-BPM可提高计算精度。另外由于三维FD-BPM对纵向步长不敏感,可通过加大步长来减少计算时间,在提高精度的同时,不影响计算时间。

Gongye shui chuli三维电极-电Fenton法是一种在电Fenton的基础上引入三维电极电催化技术的新型高级氧化法，在水处理中得到了广泛的应用。用过量浸渍煅烧法制备负载型三维电极，以采用该电极的三维电极-Fenton法处理活性艳橙X-GN废水。通过试验研究了pH、电压、Na2SO4投加量、Fe2+投加量对处理效果的影响，并采用响应曲面法最优化实验条件。结果表明，当试验pH=4.7，电压为20.39 V，Na2SO4投加量为2.13 g/L，Fe2+投加量为2.5 mmol/L时，COD和色度去除率可以达到85.41%和92.
