查询词典 at fault

By analyzing, the fault transient component of third harmonic voltage at neutral is approximately equal to that at terminal. Choosing their sum and difference as the action and restrai nt signal respectively, the protection detects the ground fault by comparing the spectrum energy of action and restraint signals.

该保护方案根据单相接地故障后机端和中性点 3次谐波电压的故障暂态分量近似相同的特点，把两个故障分量的相量和与相量差分别作为保护动作信号及制动信号，通过比较数据窗内相应信号的谱能量检测定子单相接地故障。

"Seismicity at almost all scales is absent from most faults, before any large earthquake on that fault; the San Andreas Fault in Southern California is remarkably somnolent at all magnitudes on the section that tore in the 1857 earthquake."

"大地震在某个断层发生之前，几乎所有标度的地震活动性都存在于大部分断层之外；地震活动性在南加利福尼亚州San Andreas断层上1857年被扯断的那一段前处于一种引人注目的催眠状态。"

Aiming at the hardware architecture of high performance muter system , this paper analyze and study the fault forms in muter system carefully and set up relevant fault models for these forms , and take fault models reduction into account .

1/3页12 3 摘要：本文针对路由器的硬件体系结构，详细分析了路由器系统中的故障形式，建立了相应的故障模型，并着重进行了故障模型的化简。

At least, three types of earthquake related fault rocks including pseudotachylyte formed by typical fast fault movement, no orientated ultra-cataclasite or sinter breccias may formed by weak earthquake faulting, and stockwork microbreccias formed by autochthonous powerful shock at the source are discovered, in which some of the original sources parameters are remained.

至少区分出三种地震断层产物和两种震源破裂方式：典型快速地震断层形成的假玄武玻璃；或许与弱震有关的无组构超碎裂岩或熔结角砾岩，以及强烈原地震动成因的网脉状微角砾岩。

In this thesis,it aims at the indeterminacy of software test case,through at the building of fault model, makes use of the principle of fta,designs test case for fault model adjudging software.

针对软件测试用例的难以确定性，通过故障模型的建立，利用故障树分析原理，对故障模式判决软件进行测试用例的设计。

Because the area on the east part of the Anren county seat is near the regional primary subduction - fault, namely the NNE - trending Chaling - Chenzhou fault, the Wufengxian - Tiesitang NW- trending fault had little strike -slip measure, so the derivative stress and traction were smaller, and at the same time the regional NWW- trending principal stress was stronger, which produced NNW -trending folds.

安仁以东由于紧邻NNE向茶陵一郴州主俯冲汇聚断裂，NW向断裂走滑量相对较小，派生应力与牵引效应小，而区域NWW向挤压应力大，从而于断裂两侧均形成与区域构造线一致的NNE向褶皱。

It is misunderstood that the backup impedance protection is high-ly sensitive to the inter-phase fault,inter-turn fault and single phase-to-ground fault at star winding of the windings of generator and transformer.

有些人误认为，后备阻抗保护对发电机定子绕组和变压器各侧绕组的相间、匝间短路、YN侧的单相接地短路有很高的灵敏度。

At the same time, along with the increment of cities' railway transportation, it isharder and harder for the traditional protection equipments to distinguish the remote shortcircuit fault or the train starting correctly, especially for the fault with electricity arc ortransition resistance. This always results in the equipment operation time longer that it can'tcut off the short fault rapidly.

同时，随着城市轨道交通系统运量的不断加大，传统的保护装置越来越不能正确可靠地区分远端短路故障状态与机车起动状态，尤其是当发生远端电弧故障或经大过渡电阻故障时，往往造成保护动作时限加长。

Aiming at the existing method of fault diagnosis and its limitations,a model of expert of fault diagnosis based on rough set and neural network was put forward in the paper,which was used to diagnose fault of double local-fans system in high-gas mine.

针对现有故障诊断方法及其局限性，文章提出了基于粗糙集神经网络的故障诊断专家系统模型，并将该模型应用于高瓦斯矿井双局扇系统的故障诊断中。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
