您要查找的是不是：
- 高性能PNP管 high performance PNP transistor
- 衬底PNP管 substrate PNP transistor
- 横向PNP管 LPNP
- 结果表明：在辐照的剂量率范围内，无论是国产还是进口的双极晶体管，都有明显的低剂量率辐照损伤增强现象，且NPN管比PNP管明显。 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.
