fault n. 1.过失,过错;罪过,责任。 2.缺点,缺陷,瑕疵。 3.(猎狗的)失去嗅迹。 4.【电学】故障,误差;漏电;【地质学;地理学】断层。 5.【网球】发球出界;犯规。 Faults are thick where love is thin. 〔谚语〕一朝情义淡,样样不顺眼。 fault detection 【机械工程】探伤。 The fault is his own. 这是他自己的错。 a grave fault in a theory 理论上的重大缺陷。 a fault in the machine 机械故障。 image fault 【物理学】像差,影像失真。 numerical faults 数值误差。 a fault on the right side 因祸得福。 be at fault 1. (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。
Rotating machines ( i . e . gear - box ) are always assembly of many associated parts , such as gears and bearings . commonly , high rate of fault isolation for such machines need enough test points . since the machines are always too compact to fix enough sensors , it is significative to study on how to use fewer sensors for machine monitoring and fault diagnosis by vibration analysis of rotating machine groups 复杂的旋转机械往往由轴承、齿轮等大量零件构成,在对这样的设备进行状态监控和故障诊断时,为提高故障隔离率,通常需要为每个零件就近安装传感器,但由于机械结构的紧凑性和性价比的限制,这一点往往难以实现。
According to the comparison result , the variance analysis will not be applicable when the allowance range has to be set flexibly according to specific operation requirements although it can achieve a high rate of fault detection . for example , when the allowance range of some particular component gets bigger , the variance analysis could not precisely define the new judgment boundary 比较后发现,方差特征分析法虽然可以达到很高的故障检测率,但不适用于元件容差需根据具体要求灵活设定的情况,例如当具体情况中某个元件的容差范围变大时,用方差分析法却不能准确地定出新的判断界限。
Fault diagnosis method was researched deeply on the basis of neural network - information fusion , theory and realize steps of neural fusion fault diagnosis were proposed , then instantiation simulation was given to prove that use this method can greatly improve the recognition rate of fault diagnosis 文中着力研究了基于神经网络信息融合的故障诊断方法,提出了神经网络信息融合故障诊断的原理及实现步骤,并结合具体电路进行了仿真分析,结果表明利用神经网络信息融合进行故障诊断能够提高样本的正确识别率。
