MAIN ABSTRACTS

A predator-prey system with stage structure and cannibalism is investigated. By using the comparison theorem, it is shown that the system is uniform persistence under some appropriate condi- tions. By constructing Lyapunov function,the gobal stability of the system is obtained.

01 Comparison of Multifractal Spectrum of Cantor Set Formed by Different Probability Factors
ZUOFei （Yancheng Teachers University,Yancheng 224002）
Abstract：In order to research the change status of multifractal spectrum of Cantor set and reflect difference within them under different probability factors,a kind of quality distribution of Cantor set is selected for researching its muhifractal spectrum. When quality is given with different ratio of probability,

1 Implementation of Parallel ADI-FDTD in Cyclic Reduction PDD
LI Tai-quan , CHEN Wei （Yangtze University, J ingzhou 434023）
Abstract： The key for parallel implementation of ADI-FDTD is the solution of tri-diagonal linear sys- tem. A new decomposition method is proposed to realize the parallel solution of tri-diagonal linear e- quations, which remains the correction equations in tri-diagonal linear equations and diagonally domi- nant. The correction equations are solved in the cyclic reduction algorithm. Based on the precondition precision and the diagonally dominant of tri-diagonal system, the appropriate reduction times are deter- mined to speed up the solution. The repeating calculation characteristics of FDTD are considered, the appropriate intermediate quantity can reduce both computational complexity and communication corn- plexity, but more storage space is highly required. Numerical examples verify the correctness of the algorithm.
