Calculation of Hugoniot properties for shocked nitromethane based on the improved Tsien's EOs

Acta Mechanica sinica 2010年第3期26卷 365-370页

作者： Bo Zhao Ji-Ping cui Jing Fan Key Laboratory of High Temperature Gas Dynamics Institute of Mechanics Chinese Academy of SciencesBeijing 100190 China

we have calculated the Hugoniot properties of shocked nitromethane based on the improved Tsien＇s equa- tion of state （EOs） that optimized by ＂exact＂ numerical molecular dynamic data at high temperatures and pressures. Comparison of the calculated results of the improved Tsien＇s EOs with the existed experimental data and the direct simu- lations show that the behavior of the improved Tsien＇s EOs is very good in many aspects. Because of its simple analytical form, the improved Tsien＇s EOs can be prospectively used to study the condensed explosive detonation coupling with chemical reaction.

THE DELAYED BARBOUR＇s MODEL FOR sCHIsTOsOMIAsIs

引用

International Journal of Biomathematics 2012年第2期5卷 117-137页

作者： LONGXING QI JING-AN cui school of Mathematical sciences Anhui University Hefei 230601P.R.China College of science Beijing University of Civil Engineering and Architecture Beijing 100044 P.R.China

The transmission of schistosomiasis involves latent periods of infected hosts. In this paper, considering the latent periods of infected human, infected bovines and infected snails, we propose a delayed Barbour＇s model with two definitive hosts and define basic reproductive number. The stability of equilibria for the systems with and without time delays are both investigated. To study the impact of the latent periods on the transmission of schistosomiasis, some sensitivity analysis of the basic reproductive number on the three time delays are carried out. It is shown that the basic reproductive number decreases as the three time delays increase. Furthermore, the impact of the latent periods of infected snails on the system is stronger than that of the latent periods of infected human and infected bovines. Thus, to reduce the prevalence of schistosomiasis infection, prolonging the latent periods of infected snails by some measures could achieve better results than prolonging the latent periods of infected definitive hosts.
