故障测试

The motor is provided with a thermal motor protector (a protective device that is sensitive to both temperature and current) that prevents the temperature of the motor windings from becoming more than 125°(257°) under the maximum load C F under which the motor runs without causing the protector to cycle, and from becoming more than 150°(302° with the rotor of the motor locked; or C F) 4 The motor complies with the requirements for impedance-protected motors; b Under wiring, unless the wiring complies with the VW-1 (Vertical-Specimen) Flame Test in the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581; c Under an unenclosed switch, transformer, relay, solenoid, and the like, unless it 7 舞台灯标准 can be shown that malfunction of the component does not result in a fire; or d Under field- and factory-made splices and overload and overcurrent protection devices.

F C F 4 发动机符合阻抗保护发动机的要求； b 配线，除非电线符合VW-1及参考UL 1581标准的有关电线，电缆及线芯灵活性的焰火测试。 c 未封装的开关，变呀器，继电器，螺线管及与其相似的，除非它可显示元件的故障不会引起火灾。 d 在户外和生产工厂接合过载和过流保护装置。

How to analyze the tested data is the key of veracity of fault location.

Because software failure cause is anfractuous and available data are hard to get,a modelling method for bottom event is proposed based on Vague set to calculate the relative significance of bottom event and the occurrence probability of top event.

针对软件故障原因错综复杂，无法获取大量有效数据的情况，给出一种采用Vague集方法对底事件进行建模，从而计算底事件相对重要度和顶事件发生概率的定量分析方法，根据分析结果指导软件的可靠性设计并确定测试重点。

The final experiments shows that TRI P+P algorithm can not only deal with the sequential circuits containing only 2-valued element but can also deal with the sequential circuit containing both 2-valued elements and tristate elements efficiently.

这样就减少了无效的故障模拟，从而提高了测试的效率，实验结果表明，TRI P+P算法既能处理通常的只含二值元件的时序电路，又能处理含有二值，三值元件的混合时序电路，并且具有较高的效率。

By instrumenting a system, the tester can uncover situations that lead to degradation and possible system failure.

通过插装一个系统，测试人员可以发现导致局势恶化和可能的系统故障。

These two warehouses are the most basic and important warehouse in the system.

它是测试人员的工作平台，是构成故障诊断专家系统的重要组成部分。

In order to improve the measurement accuracy of leakage current of zinc-oxide lightning arresters to ensure the validity and reliability of false diagnosis for the equipment, the wavelet transformation is applied to eliminate the noise in the test signal.

为提高氧化锌避雷器泄漏电流的测试准确度，以确保设备故障诊断的有效性和可靠性，采用小波技术对现场信号进行消噪处理。

So the research on the measurement and diagnosis system of elevators will bring great progress in this industry.

电梯综合测试系统与故障诊断技术的研究，对电梯行业的发展将会起到巨大作用。

In the past to the near-end crosstalk testing can only provide the results of cross-talk occurred in the frequency domain, that is what can only be aware of cross-talk occurred in the frequency, and unable to report the physical location of crosstalk occurs, such an outcome is far from meeting the field to address crosstalk failure demand.

以往对近端串扰的测试仅能提供串扰发生的频域结果，即只能知道串扰发生在哪个频点，并不能报告串扰发生的物理位置，这样的结果远远不能满足现场解决串扰故障的需求。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
