对黑体辐射场（包括零点分量）的直接动力学和统计分析有助于揭示普朗克光谱分布公式的关键要素。真空涨落在形式上等价于量子电动力学的涨落，在物理意义上可以用一个真实的涨落场来表示，该涨落场具有固定的能量E0=12 ω/简正模;热场被加到真空中，有它自己的涨落，从而导致完全的黑体辐射。这种分析的结果可以从一个新的角度来解决Unruh问题，并讨论了由参考系的恒定加速度修改的真空场的性质。结论是，适当考虑零点场有助于理解（真实）黑体辐射光谱和从加速框架中看到的所谓热辐射光谱。
A straightforward dynamical and statistical analysis of the blackbody radiation field, including the zero‐point component, serves to disclose the key elements leading to Planck's spectral distribution formula. A clear physical sense is assigned to the vacuum fluctuations —which are formally equivalent to those of quantum electrodynamics— in terms of a real fluctuating field with fixed energy E0=12ℏω per normal mode; the thermal field is added to the vacuum, with its own fluctuations, thus leading to the full blackbody radiation. The results of this analysis allow to address the Unruh problem from a fresh perspective and discuss the nature of the vacuum field modified by a constant acceleration of the reference system. The conclusion is that a proper consideration of the zero‐point field is clue to understanding both the (true) blackbody radiation spectrum, and the spectrum of the so‐called thermal radiation seen from an accelerating framework.
