Number density of different molecules at the end of  Dark Ages  is important
for scenario of formation of Population III stars and Epoch of Reionization.
If dark matter is warm and consists from decaying or self-annihilating particles
then formation/dissociation of molecules depends on its nature. We discuss
the possibility to make of use of  primordial species observed at the largest
radio telescopes in China (FAST and 21CMA) to constraint the warm dark matter
parameters (density, mass and life time of particles).

As for dark energy problems, we revealed that the dynamical structure of the
cosmic voids is sensitive to the parameters of dark energy models. So the
determinations of spatial distributions of galaxies and its peculiar
velocities observed in large voids in future observations could be a new
test for dark energy parameters.
