This paper introduces a new method of studying the generating path of cutter, which is called arithmetic of finishing machining based on of reversed section.

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 reaction cross-section of ~ 93Nb(n,2n)~ 92mNb was measured by activation method in the neutron energy range of 13.

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.

Full quantum mechanical studies of the H+H_2 reaction cross section;

In the framework of the extended Glauber theory, we studied the reaction cross section for the halo nucleus 14 Be scattering on a target 12 .

Based on the continuum discretized coupled channels (CDCC) theory,with the suitable initial values and boundary conditions,as well as the P3C5 algorithm to solve the coupled equations,a new code CDCCOM with higher calculation precision is written to observe the deuteron breakup effects on elastic scattering angular distributions and reaction cross sections.
