Some kinds of singular dynamic phenomena were observed in a pin-to-plate gas discharge system when the axial stiffness of a support of the pin electrode was low. One was vibration of the pin electrode perpendicular to the plate electrode observed at the transition from the dark discharge and the positive corona discharge due to the streamer corona. Similar vibration was observed in the negative corona discharge due to instability of the negative corona. Both vibrations were the forced vibration due to pulsative or fluctuating electrostatic force caused by ionic wind at corona discharging. Another axial vibration was observed at spark discharge for the softly supported pin electrode. The vibration was coupled with the occurrence of the spark discharge. The force applied to the pin electrode at the spark discharge was implicitly evaluated and it was elucidated that the force was attractive, in the order of 1 mN, and it became large in accordance with the increase of the applied voltage. Although the reason why attractive force is induced during the spark discharge is not clear so far, these phenomena are expected to be utilized for the design of a new ozone-free charger and the clarification of a fundamental mechanism of "bead-carry-out" in a two-component magnetic brush development subsystem of electrophotography.

当针电极支架的轴向刚度较低时，在针对板气体放电系统中观察到一些奇异的动态现象。其一是在由流光电晕引起的暗放电和正电晕放电的转变过程中观察到的针电极垂直于板电极的振动。由于负电晕的不稳定性，在负电晕放电中观察到类似的振动。这两种振动都是电晕放电时离子风引起的脉动或波动静电力引起的受迫振动。对于软支撑的针电极，在火花放电时观察到另一个轴向振动。该振动与火花放电的发生相结合。对火花放电时施加在针电极上的力进行了隐式评价，可知该力具有吸引力，为1mN左右，并且随着施加电压的增加而变大。尽管目前尚不清楚火花放电过程中产生吸引力的原因，但这些现象有望用于新型无臭氧充电器的设计以及阐明“珠带出”的基本机制。在电子照相的双组件磁刷显影子系统中。
