In this study, the concept of Output Frequency Response Functions (OFRFs) is applied to represent the transmissibility of nonlinear isolators in frequency domain. With the OFRFs estimated from numerical simulation responses, an explicit analytical relationship between the transmissibility and the nonlinear characteristic parameters is derived for a wide class of nonlinear isolators that have nonlinear anti-symmetric damping characteristics and a comprehensive pattern about how the nonlinear damping characteristic parameters might affect the force and displacement transmissibility is built for the vibration isolators. The results reveal that it is reasonable to analyze the force and displacement transmissibility of the nonlinear isolators by simply investigating the fundamental harmonic components of the force and displacement outputs of the nonlinear isolators, and the introduction of a nonlinear anti-symmetric damping into vibration isolators can significantly suppress both the force and displacement transmissibility over the resonant frequency region, but has almost no effect on the transmissibility at non-resonant regions. These conclusions are of significant importance in the analysis and design of the nonlinear vibration isolators with nonlinear anti-symmetric damping.

目前,已经提出了多种有源电力滤波器谐波及无功电流检测方法,尽管这些方法各有特点,但都存在着难以克服的问题,如计算量大,实时性差,检测精度不高等。文章在负载电流分析的基础上,提出了一种基于迭代算法的有源电力滤波器谐波电流实时检测方法,该方法具有计算量非常小,实时性好,检测精度高等特点。理论分析与仿真研究证实了该方法的正确性。

本文提出了一种利用多光子非线性效应的多光子结构光照明超分辨显微成像(multiphoton-structured illumination microscopy, mP-SIM)技术,可实现比线性SIM 更高的成像分辨率。通过扫描正弦结构的照明光激发样本产生多光子荧光信号或谐波信号,从而利用由光学非线性效应产生的非正弦结构信号光的谐波来提高分辨率。本文提出了mP-SIM 理论以重建系统的超分辨图像。如果考虑多光子非线性效应的所有高阶谐波(阶数足够高,即m足够大),则mP-SIM 在理论上可实现无限分辨率。通过实验证实了双光子荧光(2P)-SIM 和二次谐波产生(second harmonic generation, SHG)-SIM 分别可实现86 nm 和72 nm的横向分辨率。对细胞内染色F-肌动蛋白和小鼠尾腱胶原纤维成像,进一步验证了mP-SIM 的超分辨成像能力。该方法不但适用于多光子荧光超分辨显微成像,而且适用于非标记的如SHG等超分辨显微成像;重要的是,该方法不需要特定的荧光团或高功率激发光,可直接用于商用mP显微系统来实现超分辨成像。
