| 内容記述 | This paper described the discharge classification under nonuniform electric field in air and He at low gas pressures for the application of HV technology to the power apparatus in space. In order to discuss quantiatively the change of the discharge, an image processing method was introduced. In the first place, 4 shape parameters were proposed to characterize the discharge pattern: the area S<sub>H</sub>, the flatness rate H/V, the location g of the center of luminosity of the luminous area, and the length L of the positive column. The analysis with the image processing for air revealed that S<sub>H</sub>, H/V and g continuously increased as the pressure decreased. Consequently, the discharge type in air was successfully classified into 3 regions with two boundary pressures 200 and 2000 Pa over the pressure range from 1.3×10＾4 to 27 Pa. The discharge in He was also analyzed i the same way. Another parameter, the effective current density J<sub>e</sub>, was introduced, which was defined as a ratio of the discharge current to the luminous area viewed from the vertical direction. J<sub>e</sub> proved to be independent of the discharge current I<sub>d</sub>, so that there is the possibility that J<sub>e</sub> was suggested as universal parameter to classify the discharge in a nonuniform electric field in vacuum. | |||||
