• 你一张嘴就胡说在50Hz工频以下有个P的电磁辐射啊. - bluesea (0 bytes) 06:38:58 10/12/04 (14)
  • 谁告诉你50Hz频率下没有电磁辐射? - fagus (134 bytes) 11:29:23 10/12/04 (0)
  • 电磁辐射下限为零，键盘无害，仙人掌胡说。核辐射也是电磁辐射。 - 无知 (7 bytes) 08:22:11 10/12/04 (12)

        • I agree with you that EM wave( y ray) can be part of nuclear radiation - 008 (0 bytes) 23:23:09 10/12/04 (1)
          • I didn't say so. what kind of nuclear radiation is 50Hz? - 无知 (0 bytes) 08:09:44 10/13/04 (0)
    • 核辐射也是电磁辐射? - fagus (0 bytes) 11:32:12 10/12/04 (7)
      • yes. - 无知 (0 bytes) 11:40:40 10/12/04 (6)
        • alpha, beta, gamma, all of them? :D - Smashedmouth (0 bytes) 14:34:23 10/12/04 (5)

            • Well, you do need some basic ideas about alpha and beta rays - wasguru (90 bytes) 16:07:33 10/12/04 (2)
              • shit. 有问题。能量不是频率乘普朗克了？ - 无知 (0 bytes) 16:23:13 10/12/04 (1)
