Study of atomic average covalence electron density in EET;

Calculation of electron density on γ-Fe(111),Co(0001),Ni(111),C(0001) crystal plane and valence electron structure analysis of catalyst action;

Experimental research on electron density in solid-rocket motor plume;

In order to provide a plasma environment of high energy and low density, vertical and parallel microwave input models are designed at the entrance of the plasma source to increase electronic density and temperature.

The numerical results show that the electronic energy spectrum is shifted, the chemical potential is not equal to the atomic energy level, the electronic density at each lattice point is changed, and the variation of electronic density at surfa.

On the base of the ionospheric occultation data from COSMIC system,we analyzed the max electronic density of ionospheric F2 layer(NmF2)over seismic preparation zone from April to the end of May.

In this study, Density Functional Theory (DFT) calculations were carried out to investigate the geometries, vibrational frequencies and Laplacian electron density of cycloolefine CnH2n-2(n =3 -6) at the B3LYP/6 -31G* level.

Based on a modern ICCD spectral instrument and time-control statistic sampling method,the dynamic variations of electron density during the period were observed in alternative TIG welding arcs for bo.

A connectivity index ( mD) of valence electron density is defined as: mD=∑(δ d i·δ d j·…) 0 5 and δ d i is valence electron density of bonding atom i.
