环境中存在大量的旋转运动能量,可以使用能量俘获技术将其转换为可用的电能,进而为嵌入式设备和无线传感器提供持续稳定的电能,以解决传统化学电池供电带来的环境污染和维护成本高等问题。为了提高能量俘获系统在超低频(低于3 Hz)旋转环境中的能量俘获性能,本文提出一种具有低势垒特性的时变势阱磁耦合双稳态能量俘获系统。在充分考虑了离心效应影响的前提下,基于能量法和拉格朗日方程在旋转坐标系下推导了该系统的分布式参数机电耦合方程。通过建立该系统的磁力计算模型以分析磁间距和离心效应对系统势能阱及能量俘获特性的影响。数值仿真结果和实验结果均验证了与传统线性能量俘获系统相比,本文提出的时变势阱磁耦合双稳态能量俘获系统具有更宽的工作频率范围(0~2.67 Hz)和更高的输出电压(大于2 V)。

关键词：旋转能量俘获超低频双稳态时变势阱低势垒

光催化技术可以利用光生电子将易溶解的U(Ⅵ)还原为难溶解的U(Ⅳ)。本工作在不引入有机模板或辅助添加剂的情况下,合成了分级大/介孔g-C_(3)N_(4)-TiO_(2)复合材料,并用于光催化还原U(Ⅵ)。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、全自动比表面积物理吸附仪(BET)、紫外-可见漫反射光谱仪(UV-vis DRS)等先进表征设备对g-C_(3)N_(4)-TiO_(2)复合材料的形貌结构和光学性质进行了研究。通过光催化实验对g-C_(3)N_(4)-TiO_(2)复合材料光催化还原U(Ⅵ)的性能进行了研究。结果表明:g-C_(3)N_(4)-TiO_(2)复合材料兼具分级大/介孔TiO_(2)和g-C_(3)N_(4)的优点,不仅具有大的比表面积(174.68 m^(2)/g)和长通道,而且具有更广的光吸收范围。因此,g-C_(3)N_(4)-TiO_(2)复合材料在15 min内对U(Ⅵ)的去除率就高达98.4%。本工作对光催化处理含铀放射性废水提供了新的思路。

This paper demonstrates the limitation of the traditional multi-fractal wavelet model （MWM）. Through analyzing the multi-resolution behaviors of the real video traffic, we propose an improved MWM model. It synthesizes the traffic traces using another wavelet basis, and can adjust wavelet coefficients and multiplicative coefficients at each time scale, based on the network measurement. Subsequently, multifractal spectra and queue performances of the new model have been analyzed. The simulation proves it can capture the multifractal behaviors of network traces.
