[en] The simulation of the 3D-cylinder reactor core neutron space-time kinetics by improved quasi-static method was studied, and the computation program was developed. For the supposable modular high-temperature gas-cooled reactor model, the core neutron space-time kinetics was simulated. The calculated results obtained from this program and CITATION code are accord with each other at the initiatory state. The variance of the core reactivity, the average neutron fluence rate of each group, and the relative power along with time were computed for the dynamic simulation of the given model. The requirement of the real-time computation is satisfied under a certain precision. (authors)

[en] Community structure is an important characteristic in real complex network. It is a network consists of groups of nodes within which links are dense but among which links are sparse. In this paper, the evolving network include node, link and community growth and we apply the community size preferential attachment and strength preferential attachment to a growing weighted network model and utilize weight assigning mechanism from BBV model. The resulting network reflects the intrinsic community structure with generalized power-law distributions of nodes' degrees and strengths.
