谢谢了！

真是好风气支持

:P不要惧怕英文资料，试着去弄懂它，如果有哪一点不懂，可以上传大家讨论，这样让我们大家都热爱看英文资料。因为翻译过来的，大部分有点偏差了。

GR487后面是有core的，我具体想了解的是GR487:Sec3.28.2的内容[/quote]

我好像也有点映象在哪见过类似的GR类的标准。但是你这个手头上倒是没有，盼其它同仁分享一下。

谢谢您的回复！:)

非常感谢版主的回复！GR487后面是有core的，我具体想了解的是GR487:Sec3.28.2的内容，请问版主是否有相关资料，谢谢～～

GR487好像是个预计的标准吧。有点像是bellcore之类的标准。

GR487后面有core么？我在百度上搜的是电器设备机柜通用要求，后者是界面湿度移动双端的试验方法
