Ⅰ.引言 彩色显象管最常发生的损坏事故之一是沿管颈内壁的跳火。伴随此现象,明显看见玻(?)(艹二)色辉光,且通常愈趋强烈,直到发生击穿事故。这种事故发生的时间间隔通常为若干分之一秒到一分钟,在管子寿命期间,发生次数随时间减少。 本文将阐述一种跳火形式,讨论实验情况,目的在于论证跳水发生过程中的各种状态。并计算了电子雪崩所要求的玻颈充电电荷。最后,讨论抑制击穿的各种方法。
I. INTRODUCTION One of the most common types of damage to color picture tubes is flash over the inner wall of the neck. Accompanying this phenomenon, the glass (?) (艹 2) color glow is obviously seen, and usually becomes stronger until a breakdown occurs. The time between occurrences of such accidents is usually a fraction of a second to one minute and the number of occurrences decreases with time during the life of the pipe. This article will describe a form of flashover to discuss the experimental situation, the purpose is to demonstrate the occurrence of diving in various states. And calculated the charge required by the neck of avalanche charge. Finally, discuss ways to suppress breakdown.
