基于狭义相对论的基本观点, 研究了特征X-ray的产生机理, 分析了在狭义相对论下转动质量效应对X-ray光谱的影响, 导出了一个计算X-ray特征波长的公式, 同时对计算推导的特征波长值做了系统的误差分析, 得到了相对误差的规律。 结果表明, 计算推导的波长值与实验的波长值相比是非常的接近的, 并且随着原子序数的增加, 转动质量效应对特征波长的影响越来越明显, 研究结果在实际应用中对分析特征X-ray光谱具有一定的参考意义。

Based on special relativity, the formation mechanism of characteristic X-ray has been studied, and the influence of rotational mass effect on X-ray spectrum has been given. A calculation formula of the X-ray wavelength based upon special relativity was derived. Error analysis was carried out systematically for the calculation values of characteristic wavelength, and the rules of relative error were obtained. It is shown that the values of the calculation are very close to the experimental values, and the effect of rotational mass effect on the characteristic wavelength becomes more evident as the atomic number increases. The result of the study has some reference meaning for the spectrum analysis of characteristic X-ray in application.
