风机叶片的裂纹和断裂是导致风机机组事故的重要因素之一，尽早诊断出风机叶片的 故障部位与故障程度，对安全生产具有意义重大。本文将叶片振动信号作为研究对象，利用小波分解方法对其进行信号分解，并与时域和频域方法处理结果进行对比分析，得出诊断结论。仿真结果表明: 小波分解方法可以更有效的获取故障特征信号，具有较高的故障诊断率。(The crack and fracture of fan blade is one of the important factors that cause the accident of fan set. It is important for safety production to diagnose the fault location and failure degree of fan blade as soon as possible. In this paper, the vibration signal of the blade is taken as the object of study. The signal is decomposed by the wavelet decomposition method, and the results are compared with the time domain and frequency domain methods. The diagnosis conclusion is obtained. The simulation results show that the wavelet decomposition method can acquire the fault characteristic signal more effectively, and has higher fault diagnosis rate.)

汽车信号灯控制系统 汽车上有一转弯控制杆。此控制杆有三个位置： 1、 中间位置时，汽车不转弯； 2、 向上时，汽车左转； 3、 向下时，汽车右转； 4、 汽车转弯时，要求左右尾灯、左右头灯和仪表板上的2个指标灯相应地发出闪烁信号； 5、 当应急开关合上时，所有6个信号灯都应闪烁； 6、 汽车刹车时，2个尾灯发出不闪烁的信号； 7、 如刹车时正在转弯，则相应的转弯闪烁信号不受影响。 8、 汽车转弯或应急状态下，外部信号灯和仪表板指示灯的闪烁频率为1HZ。 9、 停靠(合上停靠开关)：头灯、尾灯以30Hz的频率闪烁。 -car lights on the car control system is a turn-control. This control rod position are three : a middle position, the car turns; 2, upward, the vehicle turn left; 3. downward car when turning; four car turning, asked about taillights, about headlights and instrument panel in the two corresponding indicator lights flashing to send signals; 5, when a switch on the emergency, all six lights should be flashing; 6, car brakes, two rear of no flashing signal; 7. if the brakes are turning, turning corresponding flashing signal is not affected. 8, cars turning or state of emergency, external appearance and the dashboard lights flicker frequency 1HZ. 9, call (a call on the switch) : headlights, taillights to the frequ
