关于桥架防火理念的探讨...

&nbsp;有关布线产品的防火，中西方有着不同的看法，在下认为欧美的标准及理念好象更趋于合理些，当然这不等同于崇洋媚外，有些观念的确有些落后与先进之别，咱们的改革开放其实说白了就是“拿来主义”，不光是资金，还有先进技术、先进的管理经验、先进的理念等等，是我们借鉴和汲取的过程，好的我们用之，不好的我们就弃之！！！<p style="MARGIN-TOP: 0pt; MARGIN-BOTTOM: 0pt; VERTICAL-ALIGN: baseline; DIRECTION: ltr; unicode-bidi: embed; TEXT-ALIGN: center; language: zh-CN;"><u style="text-underline: single;"><span style="FONT-WEIGHT: bold; FONT-SIZE: 36pt; COLOR: #ff3300; FONT-STYLE: italic; FONT-FAMILY: 华文彩云; language: zh-CN; mso-ascii-font-family: 华文彩云; mso-fareast-font-family: 华文彩云; mso-bidi-font-family: +mn-cs; mso-font-kerning: 12.0pt; text-shadow: auto;">问 题 探 讨：</span></u><span style="FONT-WEIGHT: bold; FONT-SIZE: 36pt; COLOR: #ff3300; FONT-STYLE: italic; FONT-FAMILY: 华文彩云; language: zh-CN; mso-ascii-font-family: 华文彩云; mso-fareast-font-family: 华文彩云; mso-bidi-font-family: +mn-cs; mso-font-kerning: 12.0pt; text-shadow: auto;">
