本仪器以单次火花放电理论及信号分辨提取技术为基础,自主开发了单次火花放电光谱高速采集技术、单次火花放电光谱数字解析技术、无预燃连续激发同步扫描定位技术。并据此获得数以百万计与材料原位置相对应的各元素原始含量及状态信息。建立了统计偏析度、统计均匀度、统计致密度和夹杂物定量分析数学模型。首次采用统计解析的方法定量表征材料的偏析度、疏松度、夹杂物分布等指标。开创了金属原位统计分布分析新理论、新方法、新技术。并研制成功世界首台金属原位分析仪,实现了金属材料较大尺度范围内各组分的位置分布、状态分布及定量分布的准确信息(即对材料的化学成分、元素分布、偏析度、疏松度以及夹杂物分布的快速准确测定)。具有原始性、原位性及统计性的特点,可作为冶金工艺材料研究及质量判据。
Based on single spark discharge theory and signal resolution extraction technology, this instrument independently developed a single spark discharge spectroscopy high-speed acquisition technology, a single spark discharge spectroscopy digital analysis technology, without pre-ignition continuous excitation synchronous scanning positioning technology. According to this, millions of original contents and status information of each element corresponding to the original position of the material are obtained. The mathematical model of statistical analysis, statistical uniformity, statistical density and inclusion quantitative analysis was established. For the first time using statistical analysis method to quantitatively characterize the material segregation, porosity, inclusions and other indicators. Opened up a new theory of metal in situ statistical distribution analysis, new methods, new technologies. And the successful development of the world’s first metal in situ analyzer, to achieve a larger scale of metal materials within the location of each component distribution, the state distribution and accurate distribution of accurate information (ie, chemical composition of the material, elemental distribution, segregation, The degree of porosity and the distribution of inclusions quickly and accurately). With the original, in situ and statistical characteristics, metallurgical materials can be used as research and quality criteria.
