By virtue of foundation solutions of field intensity factors obtained by Hou\+\{\\}, exact solutions in elementary functions are derived for the stress and electric displacement intensity factors of an external circular crack in a transversely isotropic piezoelectric body interacting with various stress and charge sources: force dipoles and electric dipoles.

Rotational inertia and electrical dipole moment of resveratrol molecule;

,the interactionof insrantaneous electrical dipole moment.

Under the assumption of orthogonal electrical dipole moments of a cascade three-level atom with equally spaced energy levels,the full quantum theory is applied to study the emission spectrum of the atom interacting resonantly with a single-mode electromagnetic field in an ideal cavity.

So it avoids the distortion of electric cloud distribution in basis sets and can obtain a more precise computational result of the electric dipole moment of a given system.

In this paper,utilizing the model of variational microstructures of the crystal and variational electric dipole moments of the ligands,we study the hydrostatic pressure dependence of EPR parameter a of6 State for CaCO3:Mn2+ crystals.

Theoretically and experimentally,the relation between electric dipole moment D and rotation angular momentum I is linear approximately.

Total electron energy and dipole moment of water molecular calculated are consistent with experiment quite well.
