摘要
推导了用六级场参数表示的七级像差公式 ,分析了六级场参数和屏上边、角处会聚图形间的关系 。
The formula of the seventh order aberration was derived in terms of the sixth order field parameters.Misconvergence occurring on the edges and at the corners of the screen was discussed.The 7th order aberration formula can be of much technological interest in design and production of yokes employed in various types of color picture tubes.
