We reveal that the energy spectra of electrons-positrons in primary cosmicrays measured at atmosphere top have double structures: an excess component$\Phi^s_{e^+}(E)=\Phi^s_{e^-}(E)$ around $400 GeV$, which origins from a strong$e^+e^-$-source and the distorted background $\Phi^0_{e^-}(E)$. We supposedthat the difference between AMS-CALET and Fermi-LAT-DAMPE data origins from theenergy loss of the fluxes due to the anomalous bremsstrahlung effect at aspecial window. The evolution of spectra under anomalous bremsstrahlung effectsatisfies an improved electromagnetic cascade equation. The above spectra areparameterized and they can be regarded as the subjects exploring new physics.We suggest to check the previous applications of the Bethe-Heitler formula inthe study of the propagation of high energy electrons and photons.
