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.
基于狭义相对论，研究了特征X射线的形成机制，并给出了转动质量效应对X射线谱的影响。推导了基于狭义相对论的X射线波长计算公式。对特征波长的计算值进行了系统的误差分析，得出了相对误差规律。结果表明，计算值与实验值非常接近，且转动质量效应对特征波长的影响随原子序数的增加而更加明显。该研究结果对应用中特征X射线的能谱分析具有一定的参考意义。
