摘要
Original position statistic distribution analysis (OPA) is a new analytical method to de-termine the quantitative distribution of different chemical compositions and their states on a big scope of the materials. A new quantitative metal original position analyzer, which was invented based on the analysis technology of single discharge analysis (SDA) and a continuous scanning excitement spark spectrum without pre-excitement, can be used effectively to analyze the original position statistic distribution of the metals. Thus, the new information of the materials, such as the quantitative statistic distribution of contents of various elements and inclusions on different posi-tions in the materials, the distribution of the size of the inclusions, can be obtained. The technique can also be applied to the accurate calculation of the segregation of various elements in the mate-rials, as well as the quantitative description of the homogeneity and porosity of the materials. The concept of the original position statistic distribution analysis along with the wide utilization of the metal original position analyzer will provide researchers and scientists a new method to study the inside characteristics and properties of the materials.
