本文介绍了一种利用FPGA在手持式数字示波表中实现李沙育图形的新方法。
In this paper, we introduce a new way that realize Lissajous figure in the portable digital oscilloscope with FPGA.
直线插补采用梯形曲线模式，圆弧插补采用李沙育图形原理。
The line interpolation adopts trapezium mode, and the arc interpolation adopts the principle of Lissajous Pattern.
重点阐述大气压下辉光放电（APGD）技术的现状，解释了电子雪崩模型和流注放电理论，并以电压- 电流波形图和电压-电荷李萨育图鉴别介质阻挡放电与大气压下辉光放电。
The common models to explain APGD are electron avalanche model and streamer discharge model. APGD and DBD can be distinguished by voltage-current waveform and voltage-charge Lissajous figure.
