It is anticipated that the results should provide a helpful reference for quality control of alumina ceramics, as well as the technologies with respect to materials and vacuum electronics.

希望能为电真空用氧化铝陶瓷的质量控制和检验提供理论依据，同时也为工艺方法(包括材料工艺和电真空器件工艺)的选择提供有益的技术参考。

ELECTRONICS made a huge leap forward when the delicate and temperamental vacuum tube was replaced by the robust, reliable transistor.

当初强韧可靠的晶体管取代了脆弱不稳的真空管，为电子元件带来了飞跃性的进步。

"Ultimately, incandescent light bulbs will end up in a museum, just like vacuum tubes did for electronics," he says.

他讲，“最后，白炽灯会进博物馆，就像电子学的真空管那样。”

The lessons from disruptive innovation suggest that these technologies may never be as good as the absolute best human tutor (for example, the raw capacity of vacuum tubes still outpaces that of transistors, which disrupted the vacuum tubes in the consumer electronics market), but they will be plenty close.

"When you slide that door open, all of the electronics are exposed to the near-vacuum, so we had to develop a solid-state breaker that was monitoring actual loads across that circuit, " Thompson said.
