一、问题提出回收有内刻线的示波管锥体时,要洗去其锥体内的铝层、石墨层、荧光粉层等,必须用到碱和酸等溶液,而碱和酸对用由低熔点玻璃粉为材料的内刻度线有腐蚀作用,往往锥体虽然回收了,却破坏了屏面内刻度线。因此想除净内刻度线十分困难,屏上总是留有内刻度线残迹。如果再做内刻度线,与旧

First, the question put forward the recovery of the oscilloscope with a groove engraved cone, to wash away the conical aluminum layer, graphite layer, phosphor layer, you must use a solution of alkali and acid, and alkali and acid on the use of Glass beads from the low melting point for the material within the scale line corrosion, although the cone is often recycled, but undermine the scale line within the screen. Therefore, in addition to the net inside the scale line is very difficult, the screen always leave the inner scale line remnants. If you do the inner tick, with the old
