在Ⅱ代倒象微光管的研制中防止管内近贴电极的放电击穿一直占据十分重要的地位。只有在管子的结构设计、工艺措施和测试老炼等方面对这个课题都有认真、可靠的措施后,使管内放电现象得到基本解决,才有可能做出达到国外同类管型技术指标的管子。可见解决这个问题并非那么轻而易举,它取决于多因素复杂影响的结果。即使管子已经研制成功并生产定型,只是在制造中对某一重要因素的疏忽都将导致管内放电现象的再度发生。 It has been very important to prevent the discharge breakdown in the tube near the electrode in the development of Ⅱ inverted fluorescent tube. Only in the structural design of the pipe, process measures and test aging, etc. on this issue have serious and reliable measures, the discharge phenomenon in the tube to be basically solved, it is possible to achieve the same type of tube technology indicators abroad pipe. Visible to solve this problem is not so easy, it depends on the results of the complex multi-factor impact. Even if the tube has been successfully developed and the production of stereotypes, but in the manufacture of a major factor for the negligence will lead to the re-occurrence of tube discharge.
