您要查找的是不是：
- 高性能PNP管high performance PNP transistor
- 襯底PNP管substrate PNP transistor
- 橫向PNP管LPNP
- 結果表明：在輻照的劑量率范圍內，無(wú)論是國產(chǎn)還是進(jìn)口的雙極晶體管，都有明顯的低劑量率輻照損傷增強現象，且NPN管比PNP管明顯。The results show that enhanced low-dose-rate sensitivity (ELDRS) exists in both domestic and imported bipolar transistors, and the NPN transistors are more obvious than PNP transistors.
