  volume polarization
Calculation of the volume polarization field of a relativistic particle
      
Simulation of volume polarization for the influence of solvation on chemical shielding
      
A previous work has demonstrated the strong influence on this property from volume polarization, which describes that part of the reaction field arising from solute charge density penetrating outside its cavity.
      
The essentially exact treatment of volume polarization used in that work is computationally demanding, and a more facile method for simulation of the volume polarization has recently been proposed.
      
It is found in the present work that this simulation of the volume polarization yields results in excellent agreement with the essentially exact treatment of the strong volume polarization effects on nitrogen shielding in CH3CN.

Developments of polarization mechanism of the ferroelectries are discussed as well as microdomain and superparaelectric state in terms ot the research by the author on order-disorder transition in PST and polarization-depolarization process in PLZT. The microdomains in PST and PLZT were successfully observed and clear photographs were obtained.
