5In subliminal affective priming task, there were no significant differences of P2 and P3 between alexithymic and nonalexithymic, including the peak latencies and the peak amplitudes; On both two levels of supraliminal priming tasks, the alexithymic was characterized by the decreased P2 peak amplitude and P3 peak amplitude.

6在阈下启动任务中的&启动-非启动&差异波N600的波幅方面，述情障碍组与非述情障碍组之间不存在显著差异，而在阈上启动任务的两个SOA水平中，述情障碍组的差异波N600波幅显著小于非述情障碍组的N600波幅。

In order to calibrate the model, data of six typhoons such as the flood peak and the peak time are collected to compare with the result of the simulations. The result shows that the difference of the inflow hydrograph between them is very close. The average error of the flood peak is 5.21%. Furthermore, the error of the peak time is less than one hour but Wenny Typhoon is an exception by more than two hours. Therefore, the model could be applied to simulate the rainfall event at Shih-men watershed.

为验设模式模拟精确性，本研究以具代表性之六场台风降雨模拟，针对石门水库入流历线之观测流量与模拟值比较，结果显示模拟之水库入流历线与观测值差异不大，其尖峰流量误差绝对个平均为5.21%；另在预测洪峰到达时间方面，除温妮台风迟迟2小时外，其余均在1小时内，显示本分析模式可应用於石门水库上游集水区暴雨事件模拟。

The signals during transformer impulse test are considered to be evolving in time, also is non-stationary signals, so we can design a software algorithm for noise reduction based on discrete Gabor transform, and the basic principle is: The Gabor coefficients of Effective signals during transformer impulse test is centralized in the time frequency range, and the peak-to-peak value is big, whereas the noise Gabor coefficient distribute in the entire time frequency range equally, the peak-to-peak value is small, we can realize the desired signal and the noise separated through frequency mask function.

考虑到冲击试验中的信号都是时变信号，也就是非平稳信号，因此设计了一种基于离散GABOR变换的软件滤波算法对冲击信号进行滤波，其滤波理论依据是：有效信号的Gabor系数在时频域分布比较集中，幅值比较大，噪声的Gabor系数均匀分布于整个时频域，幅值较小，通过构造时频掩模函数来实现有效信号与噪声的分离。
