论文摘要
在电偶极近似中，带电的谐波振荡器与辐射场相互作用的模型变得二次且可溶，但是对于光子频率，它需要紫外线截止。该模型的可授权性仅显而易见。物理需要保持有限的截止。该截止作用是表征光子横截面的高频行为的参数的作用。
In the electric dipole approximation the model of a charged harmonic oscillator interacting with the radiation field becomes quadratic and soluble, but it needs a UV cutoff for the photon frequency. The model's renormalizability is only apparent; physics requires that the cutoff be kept finite. The cutoff plays the role of a parameter that characterizes the high frequency behavior of the photon cross section.
