从经典的湿法化学分析到目前各种高精尖测试仪器设备 ,现代测试技术发展层出不穷 ,从而给材料工作者提供了准确、快速、可靠的数据。而用钢花观察法来检验钢的化学成分的方法几乎被人们所淡忘。虽然钢花检验法对化学成分的判断精确度不高 ,对比较复杂的材料鉴别有困难 ,但该方 From the classic wet chemical analysis to the current high-precision test equipment, modern testing technology is emerging, thus providing material workers with accurate, fast and reliable data. The method of checking the chemical composition of steel by the observation of steel flowers is almost forgotten by people. Although the steel flower test method to determine the chemical composition of the accuracy is not high, the identification of more complex materials difficult, but the party
