The analysis of 3D noise indicates that the measurement is effective. Two MRC models of ICCD imaging system has been established based on system performance of energy and modulation transfer whose target is three-bar. One MRC model is under the condition of standard A lamp, and the other is under the condition of night photo-spectrum. Because the MRC models integrate sensitivity, noise, target spatial frequency, MTF and the performance of human eye all together, the MRC models can evaluate limit performance of photoelectric imaging system more roundly.

在系统能量传递特性和调制传递特性的基础上，以三条带图案为研究对象，从信号转换的角度出发，围绕每景象立体弧度角中ICCD的电子通量，建立了基于量子噪声和CCD噪声特性的微光ICCD成像系统MRC模型，MRC模型综合了系统灵敏度和噪声、目标空间频率、系统调制传递特性以及人眼视觉特性等因素，能更全面地反映光电成像系统的极限性能。

The service brake: system's function is causes in the travel the vehicles deceleration, until the parking, is one of driving on the way most frequent use brake functions; The installment which was causes in the vehicle braking system to stop trips the automobile presence which freezes; The second braking system is in the service brake: system expires in the situation guaranteed that the automobile still could realize the deceleration and the parking installment, has listed as one of basic installments in many national this system; The auxiliary braking system uses in slowing down or the stable vehicle speed extra arresting gear.

行车制动系统的功能是使行驶中的车辆减速，直至停车，是行车途中最频繁使用的制动功能之一；驻车制动系统是使已停驶的汽车驻留原地不动的装置；第二制动系统是在行车制动系统失效的情况下保证汽车仍能实现减速和停车的装置，在许多国家该系统已列为基本装置之一；辅助制动系统用于减缓或稳定车速的额外制动装置。

The rub-impact between rotor and stator often occurs because the rotor shaft stiffness decreases following the occurrence of the crack in the rotor shaft, and thus the coupling fault with rub-impact and crack is hackneyed fault type. Based on the nonlinear dynamical model of the cracked rotor-bearing system with rub-impact, the stability of the periodic motion and instability way were studied in unbalance-rotating speed plane and rotor/stator clearance- rotating speed plane and crack depth- rotating speed plane, and the main results were validated by the experiment.

转子轴承系统裂纹故障的出现会引起转子系统转静件之间碰摩故障的发生，因此裂纹碰摩耦合故障也是转子系统常见的故障类型，本文在裂纹碰摩耦合故障转子轴承系统的非线性动力学模型基础上，分析了系统在不平衡量-转速、碰摩间隙-转速、裂纹深度-转速等参数域内，周期运动的稳定性及其失稳规律，并用实验验证了主要理论结果。
