故障模型 meaning in English
failure mode
fault model
Examples
- In chapter 5 , the author construct a fault diagnosis model with ann by an experiment on the rotor test - bed , which is an ann application of fault diagnoses of tail - wagging mechanism system . it is a precise nn by validation
第5章介绍了神经网络在高速旋转机械系统故障诊断中的应用，通过在一个转子试验台的试验，用神经网络构造了一个故障模型，经验证，该网络可以正确的诊断故障。 - And one of the basic difficulties lies in the complexity of the fault models in the analog system since both the input stimulus and output response are continuous variables , and the parameters in the circuit components are also continuous too
难点之一是模拟电路中的输入激励和输出响应都是连续量,电路中元件的参数通常也是连续的,所以模拟系统中的故障模型比较复杂,难以作简单的量化。 - By redefining the cardinality of set , we establish the relationship between the domain / range ratio and the testability metric . pie model can help us doing white box test in unit test phase . based on the fault / failure model and conditional probability , a formula is found to get testability metric , with which we prove there is a max value in software testability metric
在单元测试阶段可以运用pie模型帮助进行白盒测试,本文在软件的错误/故障模型的基础上,运用概率论中条件概率的相关知识,建立了可测试性的一个计算公式,并使用该公式证明了软件的可测试度存在一个最大值。 - The paper introduces the concept of fail - safe , the hardware and software ' s frame , divides the faults into some classes , and lists some general faults . i introduce the principle of reliability , fault forecast and it ' s standards firstly . secondly , i analyze the fmea / ca , fault tree , event tree and markov models in detail , deepen its theory and describe the flows of these models
