来点有新意的好不?别天天还周大侠一样MOV、MOV……说的那些东西多少也要有点价值啊,以为教学生念书啊?
我知道,还有个问题就是温度荷电那里。可惜想看的人不多啊。
从前编的那些东西现在还有人看吗?也算花过些心血的,但是,没什么效果。
没看懂。

没看懂。
哈哈:)真有意思。何老兄自己有家防雷公司,可比你老兄滋润多了。
提起那家公司的股东,可个个 是防雷行业的“知名”人物。
那个……自然比我水平高多了。哈哈:)

兄台喜欢的话,我再传何工关于防雷与接地讲义的powerpoint一份。
有空给我打电话啊。
祝愿你们全家身体健康,过个好年。
精力旺盛一点,还可以冲个15年,精力差一点,也就10年好冲了。过了这个年纪,武功基本也就废掉了,没得指望了。
天行健,君子自强不息。
呵呵,老弟,你误会了。你的XX也算我的朋友啊。而且……也是marchile的老朋友。哈哈。 marchile和我真的太熟悉了,算下来也是八、九年的交情,很好的朋友。
