The dependence of emission spectra line intensity and Stark broadening on the time delay, kinds and pressure of buffer gas are studied.

Electron temperature under the different time-delay and Stark broadening of the spectral line under the different gas pressure was measured and thus the electron density of the plasma was obtained.

This paper presents the principles of Stark broadening of H and non-H line profiles along with the method of Saha equation.

(1) Under the supposition of local thermodynamic equilibrium (LTE), using Stark broadening of AlⅠ394.

Under the condition of local thermodynamic equilibrium (LTE), the method of Stark broadening of AlⅠ394.

The Stark Broadening and Stark Shift with Different Electric Microfield Distribution Functions

By discussing the broadening mechanism of H spectral lines,we concluded that the main broadening mechanism is Stark broadening.

According to one spectrum of lightning return stroke in Qinghai Province,it is show that the Stark broadening are about 1.

Application of Elman neural network to width spread prediction in medium plate mill;

According to the operating principle and actual work condition of D56G90 cold ring rolling mill,two major factors,feed speed and width-radius ratio,that affected the width spread in cold rolling rectangle cross-section ring were selected to design width-spread experiment.

The distribution of specific rolling pressure, transverse stress, exit strip profile, edge drop and width spread are obtained by numerical calculations.
