Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Guangtongxin yanjiu, 2016 提出了一种基于双微环引起范诺共振效应实现超窄带滤波的微环谐振滤波器,通过泵浦波导和微加热装置使其同时具备有源和可调谐性能。通过耦合模理论,推导了该结构的透射率及超窄带带宽公式,并利用MATALAB软件模拟了在滤波器结构中注入增益对超窄带带宽和滤波器的透过率的影响,以及微环波导的热光效应对滤波器谐振波长的影响。仿真结果表明,在滤波器中注入增益能增大透过率,压缩滤波器的超窄带带宽,且微环波导的热光效应可使谐振波长发生红移或蓝移。

四川大学学报. 自然科学版, 2014 实际工作中的磁控管输出微波的功率,相位和频率均是不稳定的.本文采用有限元(FEM)计算方法,结合蛙跳技术首次模拟了考虑磁控管不稳定性时微波对矩形谐振腔中徳拜介质的加热.结果表明,磁控管的不稳定性会严重影响到微波对矩形谐振腔体中徳拜介质的加热,尤其是被加热的介质物理尺寸较小的时候这种影响更为明显.磁控管的不稳定性还会影响到微波加热的可重复性,因此在设计微波化学反应器,计算以磁控管作为微波源的微波加热时必须要考虑磁控管的不稳定性.本文建议在研究微波化学反应机理时采用稳定性更好的固态源.

Gongye shui chuli, 2015 采用微波辐射的方法对某焦化厂的焦化废水原水进行降解,考察了废水的pH、初始浓度、微波辐射的时间和功率对去除COD的影响。试验结果表明:pH=9、微波功率800 W、微波辐射4 min时,COD去除率最高达到29%。在此条件下,对焦化废水进行微波处理,用气相色谱-质谱联用仪(GC-MS)分析微波处理前后焦化废水中有机物组分的变化情况。结果表明,焦化废水经微波预处理后含氮杂环及其他多环有机物减少,而易生物降解的苯酚类单环有机物增多,其可生化性得到改善。
