According to the company, the large and heavy vacuum tube-based traveling wave tube amplifiers cannot be effectively replaced by GaAs transistors because they a much lower breakdown voltage.
根据公司的消息，真空管将不会被砷化镓晶体管取代。

The condition that plasma breakdown on Tokmak is get enough high loop voltage and large null field region in the vacuum vessel area.
托卡马克装置产生等离子体击穿的条件是在真空室区域中达到足够大的环电压以及尽可能大的零场区。

The statistical results show that the triple breaks vacuum interrupters in series have the lower breakdown probability compared with the single break one.
