发生故障

The aircraft engine fault diagnosis is very important to the airline, if can understand the engine performance and fast recognize its fault accurately then have the plan to trade sends as well as determines when the engine send to repair, avoids the significant accident, enhance the company benefit.

飞机发动机的故障诊断对航空公司有着非常重要的意义，如果能全面了解发动机性能并对其故障进行快速、准确的隔离和辨识，就可以更好的有计划的换发以及确定发动机送修时的工作范围和深度，从而大大的减少运营和维修成本，提高公司效益，并有效避免重大事故的发生。

But there are also some limitations when applying traditional fault tree analyzing method to certain systems that are amendable, complex, time consuming and with random failures that occurs randomly.

但是由于其局限性，对于具有可修复、系统复杂、昼夜连续运行、动态随机性故障发生的系统而言，传统故障树分析方法便显得"力不从心"。

So it is of great importance to detect the signal discontinuity.

在故障诊断中，故障通常表现为输出信号发生突变，因而对突变点的检测有非常重要的意义。

A backpropagation neural network model with the input matrix composed of the characteristic indexes of pressure is proposed to classify the running state of refrigerating units in order to diagnose and forecast the leakage fault.

研究了冷库制冷机组制冷剂泄漏的特征，分析了泄漏引发的流量和压力参数变化情况，并提取了反映泄漏故障的特征指标，建立了能对制冷机组运行状态进行分类的神经网络模型，以诊断和预报泄漏故障的发生。

Next, we study minimization problem of queuing time delay in network and signal quantization errors in control system based on average behavior of network rate.

针对在信息调度下和变速率采样的NCS模型，通过设计一组动态反馈故障检测滤波器，对系统发生的故障进行跟踪检测。

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。

Such failures occur in the warmer color temperature of the display (a lot of self-set color temperature display), so that the white face red failure it is best to clean your screen after you other checks, if the fault disappears - you can a few detours!

此类故障多发生在色温偏暖的显示器中（很多显示器能自行设置色温），所以说，遇到白色偏红故障时您最好是先清洁一下显示屏后再进行其它的检查，如果故障消失--您就可以少走弯路了！

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 th...

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。

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。

The diagnosis system of injector fault can diagnose clearly whether singal injector is at fault or double.

喷油嘴故障诊断系统在引擎各种转速情况下，都可以明确的诊断出喷油嘴是否发生单缸故障或是二缸故障。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
