Ionospheric Characteristic

In this article, the author uses computer graphics visual programming method and visually expresses ionospheric characteristic parameters. Firstly, the significance of visualization of ionospheric characteristic parameters was described, then visualization process and methods were discussed, and finally the results of visualization of ionospheric parameters in typical conditions were given. The results show that visualization method of ionosphere characteristic parameters can directly reflect ionospheric electron density, electron temperature and other parameters, which is conductive to an intuitive understanding of various physical phenomena in ionosphere.

AbstractThe 2D-dopant and defect distributions resulting from 80 keV ion implantation of As+ ions into Si through a high-edge mask are presented. The distributions are obtained by means of an efficient computer procedure using the results of Monte Carlo simulation. Two versions of the computer code TRIM are used. The 2D-target atom redistribution is obtained as a result of cascade collisions. The simulation reveals the effect of near-mask-edge target atom depletion. This effect is related to the recoil phenomena and can be explained on the basis of simple model.

Computer Procedure

Photoelasticity is a whole field experimental technique for the measurement and visualizing of the stress and strains in the loaded members. This work is intended to create a unique procedure that allows the use of a computer aided technique in the evaluation of the measurement results. The specimens of the thin annular disk, the thin disk and the shaped beam were tested. The PATRAN program is used for the finite element solution of stress analysis in the investigated specimens. The excellent agreement is established between the results of experimental technique based on the created computer procedure and the results of numerical computations.

Computer Procedure

The effect of varying the temperature over a wide range (4–60 degrees C) on the binding of epsilon-dinitrophenyl-L-lysine to bovine colostral anti-dinitrophenyl immunoglobulin G2 yielded a non-linear van′t Hoff plot. The extent of curvature was indicative of a large positive heat-capacity change, and the thermodynamic parameters, calculated by using a non-linear least squares computer procedure, revealed an enthalpy–entropy-compensation mechanism for hapten-antibody binding. The enthalpy factor was found to be the primary contributor for the complex-formation at low temperatures, but at increasing temperatures the entropy factor assumed greater importance. At physiological temperature (39 degrees C), the entropy factor was the major contributor to the free energy of reaction.
