摘要

实验研究了柔性电极在中压条件下产生的放电特性。在典型飞行高度压力为0.3 atm的条件下，我们根据固定电压下脉冲发生器的脉宽和频率来确定放电模式。在频率为10 kHz时，脉冲宽度为4 μs;在频率为20 kHz时，脉冲宽度为3 μs，放电均匀。为了分析放电模式的变化趋势，测量了各工况下放电的电压和电流波形。此外，根据测量的电压和电流波形计算了一个周期的功耗。测量和计算结果表明，当放电频率为20 kHz，脉宽为3 μs时，放电耗散功率大，放电模式更亮、更均匀，这是0.3 atm压力下柔性电极的最佳放电条件。

Experimental Study of Discharge with Flexible Electrodes at Intermediate Pressure for Radar Cross Section Reduction

In this experimental research, the characteristics of the discharge generated using a flexible electrode at intermediate pressure were investigated. We confirmed the discharge patterns according to the pulse width and frequency of a pulse generator with a fixed voltage under a pressure of 0.3 atm, which is the pressure at a typical flight altitude. Uniform discharge was found to occur at a frequency of 10 kHz with a pulse width of 4 μs and at a frequency of 20 kHz with a pulse width of 3 μs. To analyze the trend of discharge patterns, the voltage and current waveforms of the discharge in each condition were measured. In addition, the power dissipated by one cycle was calculated from the measured voltage and current waveforms. From the measurement and calculation results, it was confirmed that the dissipated power was large when the discharge occurred at a frequency of 20 kHz with a pulse width of 3 μs, that is, the brighter and more uniform discharge pattern, which was found to be the optimal discharge condition for the flexible electrode at a pressure of 0.3 atm.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
