In the investigated systems the "equal medium effect" for HC1 and HOAc was found.

The theory study of a plane-wave expansion method based on the effective medium technique in the two-dimensional photonic crystal;

According to seismic coherent body,this paper predicts distribution of fractures,uses equivalent medium theory,and establishes geologic model.

At present, most equivalent medium models are established in low-frequen.

For thick VTI coal bed,calculated its stiffness matrix by effective media\'s theory at first;and then,computed the P-wave AVO curve of this coal by propagation matrix method which based on anisotropy theory.

The electramotive forces (-EmV) of measured cells have been determined at 298 15 K, then the activity coefficients and medium effects ( PME、SME、 Total) of RbCl have been calculated and discussed on the basis of solvation theory of electrolyte solution.

The medium effect of nucleon-nucleon cross section σ~ med _ NN (α) on the isoscaling parameter α is investigated for two couples of central nuclear center reactions ~ 40 Ca+~ 48 Ca and ~ 60 Ca+~ 48 Ca, ~ 112 Sn+~ 112 Sn and ~ 124 Sn+~ 124 Sn with isospin dependent quantum molecular dynamics at beam nucleon energies from 40 to 60?MeV.

were effective ways to promote the alcoholysis through medium effect.

The medium effects on the △N→ NN cross section is investigated, and it is found that the effective cross sation is suppressed in the medium near the threshold energy.
