Query: Inhomogeneity of dusty crystals and plasma diagnostics   Real dusty crystals are inhomogeneous due to the presence of external forces.
We suggest approximations for calculations of different types of inhomogeneous
DC (chain and DC with a few slabs) in the equilibrium state. The results are in
a good agreement with experimental results and can be used as an effective
diagnostic method for many dusty systems.
