作为电子探针分析用标样,必须具有微米尺度空间范围的成份均匀性,用高于探针分析精度和准确度的分析方法加以定值,并且在真空中,电子轰击下具有良好的稳定性,能长期保存、使用。为了正确地鉴定这些属性以进一步判断标样的质量和实用性,应当有一套较为完善的检验方法和合理的判据,根据几年来标样工作的实践,提出以下几方面和大家一起讨论、研究。 As a standard for electron probe analysis, it is necessary to have compositional uniformity in the microscale spatial range, be set by analytical methods above the accuracy and accuracy of probe analysis, and have good stability under vacuum and electron bombardment , Long-term preservation, use. In order to correctly identify these attributes to further judge the quality and practicability of the standard samples, there should be a set of more perfect test methods and reasonable criteria. According to the practice of standard sample work in the past few years, the following aspects are discussed and discussed .
