【摘要】 本文通过多种分析检测手段与方法,利用数理统计原理和数据显著性检验技术,完全立足于自主成功研制出了用于直读光谱分析的焊丝标准样品(包括焊丝标样实物及其化学成份标准值)。不仅满足了公司生产的需要,并且极具应用推广价值,填补了一项国内空白。更多还原

【Abstract】 By using mathematic statistics prin ciple and data notability in sp ectio n technique,We tried multiple analy sis and detecting methods to develop independently the welding wire standard samples(including their stan-dard chem ical contents)used in direct reading photoelectrical spectrograph.This result not on ly satisfied the requirement of our manufacture,but also has great appl ication value.It filled a vacancy of this aspect in our country.更多还原
