| Abstract: | The phenomenologic quantum equations——the CK′s equation and the Kostin′s nonlinear Schr dinger-Lagenvin equation correspording tothe classical linear dissipasive systems are discussed by methods of SQP. The physical content of such equations is displayed more clearly in the so-called Madelung-form i. e. the hydrodynamical picture of quantum theory. The lagrangian densities corresponding to these equations are investigated as well. Especially, the nonreality of the Kostin′s Hamiltonian or nonhermitianity of the Kostin′s Hamiltonian operator is discussed. |
