摘要
针对光线示波器振动子阻尼问题 ,进行了理论分析、研究及经验总结 ,给出了调整振动子阻尼比的简捷方法。结果表明 ,该方法能够在较短的的时间内 ,保证振动子的阻尼比为 0 .70 7,满足了不失真记录的要求 ,应用方便 ,对光线示波器的正确使用具有指导意义。
Based on a theoretical study of the damping in an oscillograph vibrator and a summary of the experience gained in practice in treating the damping, a simple and direct method for the adjustment of the damping ratio of the vibrator is presented. Experimentcl result shows that by use of the method the damping ratio can be rapidly adjusted to 0.707, which ensures a correct use of the oscilloscope.
