How to measure argon plasma parameters of dielectric barrier discharge at atmospheric pressure are described, Electron temperature and electron density of argon plasma are measured and calculated from their emission spectrogram.

Six bulk metallic galsses series alloys of Zr-Al-Ni-Cu with different compositions were designed and prepared ac- cording to electron concentration constant and atomic size constant criteria.

The criteria that we have developed are respectively related to the conduction electron concentration, termed the e/o-constant criterion, and to the special cluster structure, termed the e/α-variant criterion.

A new bulk Zr-Al-Ni-Cu amorphous alloy has been designed and prepared according to the rule of constant valence electron concentrations (e/a), which satisfies e/a=1.

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.
