fault time meaning in Chinese

故障时间

Undetected fault time
未检出故障时间
The total fault time with this type of ball mill is less than a week every year
这种类型的球磨机每年的故障时间不到一星期。
Secondly , because wavelet analysis can change the time and frequency windows according to the variation of signals " frequency , it can analyze the singularity of fault signals , and then confirm the accurate fault time efficiently
接着，文章利用小波变换“变焦距”的性质，对故障信号的奇异点进行分析，确定故障时刻。
Judging by the different magnitude and direction of the wavelet packet coefficient modular maximum , we can select the single phase - to - earth line . the method using wavelet singularity detection theory to extract the fault time is discussed . a fault distance measurement algorithm combining wavelet analysis used for separating the character from the transient fault signal with artificial neural networks used for the nonlinear approximation from the transient character to fault distance is presented
论文提出利用各个出线零序电流在频带上小波包系数模极大值的方向和大小的不同来实现故障选线，讨论了利用小波分析的奇异性来判断故障启动时刻，提出将小波分析和人工神经网络结合，利用人工神经网络的非线性逼近能力，实现故障暂态量到故障距离的非线性映射，完成测距。
