6、1.1的編輯要求,根據(jù)ISO3497重新起草。本標準對應ISO3497作了如下修改:—取消了ISO3497的前言內容,重新起草r本標準前言;增加了“目次內容”;用“本標準’,代替“本國際標準”。本標準代替GB/T16921-1997《金屬覆蓋層覆蓋層厚度測量X射線光譜方法》?本標準與GB/T16921-1997相比主要變化如下:—在范圍中增加了警告;—在術語和定義中增加了基體材料、基體金屬和基體的定義,且將歸一化強度(1997年版的2.本版的2.4)的數(shù)學符號定義為二.(1997年版為In),相應的數(shù)學關系式也隨之改變;—在3.3.3能量色散中,將波長和能量的關系式進行了修正
7、;—在原理中,將其內容進行了重新排列,增加了3.5.3比率方法和3.7數(shù)學反卷積的描述;—對5.1.2隨機誤差的標準偏差、以及5.6覆蓋層密度的公式進行了修正;—對5.16試樣表面的傾斜度的影響,做了更精確的修正;一在儀器的校準中增加了6.1.5計算機模擬主要參數(shù)的無標樣技術的描述;本標準的附錄A為資料性附錄本標準由中國機械工業(yè)聯(lián)合會提出。本標準由全國金屬與非金屬覆蓋層標準化技術委員會歸口。本標準起草單位:機械工業(yè)表面覆蓋層產(chǎn)品質量監(jiān)督檢測中心本標準起草人:姜新華、凌國偉、劉建國、鐘立暢、宋智玲。本標準
