At present,the analytic tools used for the power signals in microcomputer protection include FFT,Kalman filter and finitely shock response filter,etc.They are effective to analyze stationary signals but localizable for unstationary signals analysis.Especially it is difficult to identify nonlinear fault,e.g,the nonlinear high impedance short trouble is along-term unsolved problem of power system.

目前，用于微机保护中的电力信号分析工具有FFT、Kalman滤波器、有限冲激响应滤波器等，它们对于平稳信号的分析是高效的，但在分析非平稳信号中有其局限性；尤其对非线性故障识别困难，如探测高阻抗非线性短路故障便是电力系统一个长期没有很好解决的问题。

PCB diagnosis based on infrared energy emissions is rivetting more and more attention as a new developed Non-intrusive testing technique.

目前对PCB诊断的主要方法是使用针床测试仪或人工使用探针探测电路内部节点的电信号，然后根据这些信息进行故障定位。

This paper discusses two methods of analysis that have been utilized for fault detection.

本文讨论了两种用于故障探测的方法。

In order to avoid or reduce arc fault hazard,the authors established an arc fault detecting test system with the method of power spectral analysis to study the early acoustic characteristics of fault arc ,and extracted the sound signature of early fault arc by using power spectrum analysis.

为了避免或减少故障电弧的危害，笔者建立了故障电弧探测试验系统，采用功率谱分析的方法对故障电弧的早期弧声特性进行了试验研究，提取出故障电弧的早期弧声特征信息。

Another major problem in electric power system is how to detect faults in small current's ground system.

小电流接地系统故障探测是电力系统另一具有代表性的问题。

So, telling your director of maintenance,"We are going to have to down the aircraft because our NDT test has detected an atomic anomaly in the spar that could lead to catastrophic failure" isn't so farfetched after all.

因此，这样告诉你负责维修的领导：&NDT探测到纵梁里出现了不正常的原子，这会导致严重的故障，我们准备把飞机停下来检修。&毕竟不是不可能的。

Can you picture yourself telling your director of maintenance something like Yea boss, we are going to have to down the aircraft because our NDT test has detected an atomic anomaly in the spar that could lead to catastrophic failure.

你会这样告诉负责维修的领导：&报告，无损探伤探测到纵梁里出现了不正常的原子，这会导致严重的故障，我们准备把飞机停下来检修。&

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
