(猎犬追捕猎物等时)失去嗅迹,踌躇不前;不知所措,正在为难。 2. 出毛病,有故障。 3. = in fault (My memory is at fault . 我想不起来了)。 find fault in 看出…缺点。 find fault with 找…的岔子。 have no fault to find with 无错可寻。 hit off a fault (猎狗)闻出(曾一度错失的)嗅迹。 in fault 有过错,有责任 (Who is in fault 是谁的不是?)。 to a fault 过度,极端 (He is kind to a fault. 他过分老实)。 whip a fault out of sb. 鞭打某人使之改过。 with all faults 不保证商品没有缺点。 without fault 〔古语〕无误,确实。 vi. 1.【地质学;地理学】产生断层;有断层余迹。 2.发球出界;犯规。 3.〔方言〕责备,挑剔。 4.〔古语〕犯错误,做错。 vt. 1.找…的岔子,挑剔;〔方言〕责备。 2.【地质学;地理学】使产生断层。 3.把…做错。 He faulted my speech in two ways. 他认为我的讲话有两点不妥。 fault one's performance 表演发生失误。
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。
