摘要
以Newton差商和差分插值法构建113、114号化学元素相对原子质量推算的数学表达式、结合其余项公式校正、逼近值的精确度极高,与文献[5,7]的实验值(278和289)完全一致,由此获得了令人满意的113、114号元素相对原子质量结果。
A mathematical expression based on the Newton interpolation of difference coefficient and calculus of differences was described for the prediction of relative atomic mass. In its application to the calculation of relative atomic mass of elements with atomic numbers from 113 to 114, combining residual formula correction highly precise results were obtained. The results were in good consistency with the experimental 278 and 289 values given in the references[5,7] .
