摘要:
为了研究高有机硫煤中微量元素分布与元素内部结构变化之间的规律,选取国内典型超高有机硫煤的12个样品,分析了48种元素含量和其灰分产率的相关系数平方与对应元素的第一电离能、离子半径的变化趋势,结果显示与元素第一电离能变化趋势一致的有23组,相反的有24组; 与元素离子半径变化趋势一致的有25组,相反的有22组。对比与元素第一电离能和离子半径的变化趋势发现,具有相同变化趋势的有21组,从某种程度上第一电离能表征了原子团分裂与结合的难易程度,而离子半径决定了元素的亲和性能,二者在不同背景条件下的主导作用造成了上述差异性的出现。为了定量的表征2组数据同步变化的良好程度,定义了同向同步性水平、反向同步性水平、连续同步性水平、同向连续m同步性水平和反向连续m同步性水平,根据以上几种同步性水平的定义归纳出了同步性水平评价公式。
Abstract:
In order to study the regularity between the distribution of trace elements and the internal structure of elements in high organic sulfur coal,12 samples of typical ultrahigh organic sulfur coal were selected,and the correlation coefficients of 48 elements and their ash yield were analyzed.The first ionization energy of the element and the change trend of the ion radius were investigated.The results show that there are 23 groups consistent with the change trend of the first ionization energy of the element.On the contrary,there are 24 groups.There are 25 groups with the same trend of the ion radius of the element,and 22 groups are contrary.Comparison of the trend of changeof the first ionization energy and ion radius of the elementsfound that 21 groups are of the same trend.From a certain extent,the first ionization can represent the degree of difficulty of the division and combination of atomic,and the ion radius determines the affinity element.The two under different background conditions led to the emergence of the above differences.In order to represent the synchronization of the two groups of data quantificationally,we propose the concept of synchronized level,including synthetic synchronization,reverse synchronization,continuous synchronization,synthetic continuous m synchronization and reverse continuous m synchronization.Based on the definition of the synchronized level mentioned above,the evaluating formula of synchronized level is concluded.
