  I propose a unified model of particle physic and cosmology based on both a
new extension of the standard particle model and the fundamental principle of
the standard cosmology. Beyond the SM, I introduce several species of dark
fields with the dark symmetry of $Z_{2}\otimes Z'_{2}$, the inflation field,
CDM and DE are of course included among them. The model can coherently and
completely describe the origin and evolution of the universe from the
primordial inflation to the reheating, to the baryogenesis, to the current CDM
and DE, and also the neutrino mass generation mechanism. For the energy
evolution of each phase, I give its dynamical system of equations, and solve
them by some special techniques. The numerical results can clearly show how
each evolution is successfully implemented, furthermore, the model demonstrates
that the DE genesis is purely from the CDM condensation, which is essentially a
reverse process of the primordial slow-roll inflation, there is not the
so-called ``cosmological constant energy". By use of fewer input parameters,
the model not only exactly reproduces the measured inflationary data and the
current energy density budget, but also finely predicts such important values
as the tensor-to-scalar ratio $r_{0.05}\approx1.68\times10^{-6}$, the inflaton
mass $M_{\Phi}\approx5.05\times10^{10}$ GeV, the reheating temperature
$T_{re}\approx8.29\times10^{10}$ GeV, the CDM mass $M_{S}\approx256$ GeV,
$\eta_{B}\approx6.14\times10^{-10}$ and $h\approx0.73$, in particular, the
model smoothly clarifies and eliminates the ``Hubble tension". In short, the
unified model newly establishes the deeper and closer relations between
particle physics and cosmology, therefore we expect the ongoing and future
experiments to test the model.
