Based on a series of signal process and noise source identification techniques, especially the major noise source identification methods, such as expurgation method, sound intensity analysis, spectrum analysis vibro-acoustic correlation analysis and so on, the pass-by noise control of SC7080A and SC6360B are studied in detail. By the roadway and dais experiments, the major noise and radiating parts are identified and some economical controlling methods are made. For the SC7080A, to control the emissing noise from the intake and shell vibration of air cleaner, a intake muffler is installed between the air cleaner and intake valve. Based on the theory of Helmholtz resonator, One three-parallel-connected resonant silencer is designed and trial-manufactured. For the SC6360B, the attenuation performance of exhaust muffler in high frequency region is improved. To reduce the vibration noise of shell part, the structure of oil sump tank, exhaust manifold shield and exhaust manifold shield are analyzed and improved. At the same time, some measures, such as sound absorption, sound insulation, are taken to reduce the noise of engine surface emissivity and a sound shield is designed.

Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .

如果保持偏转板的电压大小不变，改变加速极的电压，可以看到加速极的电压减小，则电子束偏转的角度反而增大，这是因为加速极电压低，则电子的水平方向速度变小，电子在偏转板中受电场力作用的时间加长，所以偏转的角度增大。
