50397 基于维修实践中设备两阶段故障过程，利用延迟时间的概念和当前时刻的状态检测历史信息，建立了改进的基于三阶段故障过程的状态检测模型。 Based on equipment maintenance practice two phase fault process, using the concept of delay time and the current state of the moment detection history information, establish an improved model based on three phase fault state of the process of testing.
50398 该模型更接近于设备的真实运行过程。 The model is closer to real operation process of equipment.
50399 设备运行有4种可能状态出现:正常状态、非严重缺陷状态、严重缺陷状态和故障状态。 Equipment operation there are four possible states: normal, non serious defects, serious defects state and fault state.
50400 当检测到系统处于非严重缺陷状态时，采用延迟预防维修策略建立模型。 When they tested the system are in a state of non serious defect, delay preventive maintenance strategy is adopted to establish the model.
50401 以单位时间设备运行平均费用最小为决策目标，优化检测间隔和阈值时间，通过参考阈值时间来决定是否实施延迟预防维修决策。 The minimum equipment run average cost per unit time as the decision objective, the optimal inspection interval and time threshold, by reference to delay threshold time to decide whether to implement preventive maintenance decisions.
50402 最后将提出的模型应用于实际案例中，验证了改进的基于三阶段故障过程的状态检测模型的有效性。 Finally, will put forward the model is applied to the actual case, to verify the effectiveness of the improved process based on the three-phase fault state detection effectiveness of the model.
50403 针对相控阵雷达导引头的隔离度寄生回路问题，分析了天线罩和导引头隔离度产生的原因， In view of the phased-array radar seeker isolation degree parasitic loop problem, analyzes the cause of radome and seeker isolation degree,
50404 建立了考虑天线罩和导引头隔离度的制导系统动力学模型， established the radome and the seeker guidance system dynamics model of the isolation degree,
50405 基于线性时不变系统稳定性判据和无量纲化法研究了天线罩和导引头隔离度共同作用对制导系统稳定工作域的影响。 based on the linear time invariant system stability criterion and the dimensionless method to study the combination of radome and seeker isolation effect on guidance system stability domain.
50406 利用无量纲伴随函数法研究了天线罩误差斜率和导引头隔离度不同叠加情况对脱靶量收敛的影响。 Dimensionless with function method was used to study the slope and seeker radome error separation different superimposition effect on convergence of miss distance.
