In this paper, the versions of quantum electrodynamics (QED) with spinors in fermion equations are briefly examined. In the new variants of the theory, the concept of vacuum polarization is unnecessary. The new content of fermion vacuum (without the Dirac sea) in the examined versions of QED leads to new physical consequences, part of which can be tested experimentally in the future.

费米子方程中带有旋量的量子电动力学中缺乏真空极化

在本文中，简要研究了费米子方程中带有旋量的量子电动力学 (QED) 版本。在该理论的新变体中，真空极化的概念是不必要的。在 QED 的检查版本中，费米子真空（没有狄拉克海）的新内容导致了新的物理后果，其中一部分可以在未来进行实验测试。
