The result shows that the in-plane orientation relation of the films in thetwo sides of the grain boundary can be easily obtained with this method. By controlling the growth condition,a 45° YBCO grain boundary can be made on the SrTiO_3 substrate.展开更多
文摘多数自然振动为平稳信号,且受光纤分布式振动传感系统的干涉光信号调制。作为事件识别关键参量之一的幅值信息无法采用传统信号分析方法准确获得。本文基于分数阶傅里叶变换在统一的幅、时、频域内更准确地提取Phase-sensitive optical time domain reflectometry(Ф-OTDR)信号的幅值信息。在分析Ф-OTDR非平稳信号形成原因的基础上,进一步讨论分数阶傅里叶变换的适用条件,最后在实际地下电气管廊第三方破坏中检测分数阶傅里叶变换提取Ф-OTDR信号的幅值信息的有效性。分数阶傅里叶变换在连续的幅、时、频域分析中,更准确地提取非平稳振动信号的幅值信息,有助于Ф-OTDR事件探测与类型分析。
