我厂是89年开始使用7503A 光电直读光谱仪的,迄今已整整5年了。该仪器性能稳定,分析精度高,在工业生产中起着重要作用。在此我们仅就在作曲线方面所遇到问题,提两条可能是不成熟的意见。众所周知,作一条新曲线是比较困难的。我厂的不锈钢合金成份较特殊,比如含Si 量较高,达4.3%左右。市场根本无此含量的标样,因此标样主要靠自制。有时几块 Our factory started to use 7503A photoelectric direct reading spectrometer in 89 years, so far it has been 5 years. The instrument has stable performance and high analysis precision and plays an important role in industrial production. Here we are just two issues that may be immature opinions on the problems encountered in the production of curves. As we all know, making a new curve is more difficult. I plant more special stainless steel alloy, such as higher Si content, up to 4.3%. The market does not have this content standard sample, so the standard sample mainly by self-made. Sometimes a few pieces
