The result shows that the expression for the first time gives reaction probability factor quantitation explanation as well as it is of clear physical meaning.

The reaction probability,the reaction cross-section and the thermal rate constants at T=300,500,and 700 K for the reaction have been evaluated,and it is indicated by comparison that the thermal rate constants calculated in this work agree well with the experimental data.

The relative translational energy and reactive cross section σ_r and the effect of relative translational energy on reaction probability are studied, and the microscopic mechanisms of the r.

The energy dependence of the calculated reaction probability shows oscillatory structures,similar to those observed in the reactions H+H 2,H+CH 4 etc.

The calculated results show that vibrational state of HCl influences its reaction probabilities greatly, the feature of PESs plays considerable role for how rotational state affecting its reaction probabilities, and the reaction probabilities appear 'Gold Rule'.

The reaction probabilities of the collinear reaction F+H 2(0)→H+HF(υ) were calculated,using the LCAC SW(Linear Combinations of Arrangement Channels Scattering Wavefunctions)method.

70 ev energy interval, through calculating the reaction probabilities of H+H 2(ν=0)→H 2(ν=0)+H reaction with LCAC-SW method.

The Doppler weather radar is the advanced radar system up to now in the world, it not only extract the reflectivity factor in the radar echo which is done by the traditional weather radar, but also extract the radial velocity and relevant spectral width of the precipitation particle, which great improved the capability of weather monitoring and forecast.
