A novel technique,in which pulse modulation was used,was successfully developed to measure the electron stimulated desorption(ESD)cross section of neutral particles,the measurement of ESD cross section of neatral particles is an important but rather elusive physical quantity.

ln this paper, based on rational Bezier curves, the modeling method of constructing solids from their cross sections is given.

The cross sections for165Ho(n,γ)166 Ho reaction have been measured relative to that ofgold at neutron energies of 203,676 and 974keV using the activation technique,The results were37.

Fibrations of congruence of lines and applications of sections;

The few group section is calculated for several in core assemblies,and the parameter section table is ordered by different Gd 2O 3 weight percent, burnup, energy group, and then the necessary sections for in core burnup are calculated with function .

Based on such a background and the soaring development of steel structures in China, the author puts forward a research program on optimization design of steel structural element sections, which is thought to have a broad prospect in practice.
