前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T25187—2010《表面化學分析俄歇電子能譜選擇儀器性能參數的表述》，與

GB/T25187—2010相比，除結構調整和編輯性改動外，主要技術變化如下：

─更改了噪聲測量方法2（見5.6.3，2010年版的5.6.3）。

本文件等同采用ISO15471：2016《表面化學分析俄歇電子能譜選擇儀器性能參數的表述》。

請注意本文件的某些內容可能涉及專利。本文件的發(fā)布機構不承擔識別專利的責任。

本文件由全國微束分析標準化技術委員會（SAC/TC38）提出并歸口。

本文件起草單位：廈門荷清教育咨詢有限公司、廈門大學、中國科學院化學研究所。

本文件主要起草人：岑丹霞、徐富春、李建輝、湯丁亮、劉芬、王水菊。

本文件于2010年首次發(fā)布，本次為第一次修訂。

GB/T25187—2024/ISO15471：2016

引言

全球有多家廠商生產俄歇電子能譜儀（AES）和掃描俄歇電子顯微鏡（SAM）。盡管每臺儀器的

AES分析方法的基本原理是相同的，但儀器的具體設計和性能說明的方式各不相同。因此，通常很難比

較不同廠商生產的儀器性能。本文件提供一個基本項目單，以使所有俄歇電子能譜儀能以共同的方式來

表述。本文件無意取代廠商的說明書，廠商的說明書可能長達30頁或更多。本文件目的是使廠商說明

書中確定的某些項目具有一致和明確的含義。
