前言根据广大厂矿日益发展的需要,从本期起开辟“有色金属标准分析方法”专栏,连续刊载美国材料试验学会(A.S.T.M)1978年版中有色金属与合金的最新化学分析、光谱分析及其他有关分析方法,供化学分析工作者参考。在译文刊出之前,特先将试剂部分(Annual Book of ASTM Standards,Pt.12 E 50)刊出,以便读者今后查对之用。所用试剂编号与原文一致,也与今后载文所指试剂号码相同。
Foreword According to the growing needs of the majority of factories and mines, from this issue onwards opened “non-ferrous metal standard analysis method” column, the continuous publication of the American Society for Testing and Materials (ASTM) 1978 edition of the latest non-ferrous metals and alloys chemical analysis, spectral analysis and other relevant analysis Method for chemical analysis workers reference. Prior to the publication of the translation, the Readers’ Special Report (Pt. 12 E 50) was first published for future reference.
