摘要
试验结果表明,显像管颈发黑是由于电子枪电极表面上的异物,在强电场作用下发生溅散的结果。调整"打高压"规范后,颈黑管由60 57%降至6 2%。
It is shown by experiment that the black neck of kinescope occurred due to unexpected materials spattered on the surface of electrodes of electron gun under the action with strong electric field. The black neck rate can be greatly reduced from 60.57% to 6.2% after the knock out voltage is properly adjusted.
