Acta Mathematicae Applicatae Sinica 2016年第2期32卷 319-326页

In this paper, we propose a susceptible-infected-susceptible （SIS） model on complex networks, small-world （WS） networks and scale-free （SF） networks, to study the epidemic spreading behavior with time delay which is added into the infected phase. Considering the uniform delay, the basic reproduction number R0 on WS networks and ~ on SF networks are obtained respectively. On WS networks, if R0 〈 1, there is a disease-free equilibrium and it is locally asymptotically stable; if R0 〉 1, there is an epidemic equilibrium and it is locally asymptotically stable. On SF networks, if R0 〈_4 1, there is a disease-free equilibrium; if -R0 〉 1, there is an epidemic equilibrium. Finally, we carry out simulations to verify the conclusions and analyze the effect of the time delay T, the effective rate A, average connectivity 〈k） and the minimum connectivity m on the epidemic spreading.

A new species of the ant genus Aenictus shuckard, A. henanensis, sp. nov., was collected from Yichuan County, Henan Province. The new species is close to A. lifuiae Terayama, but in profile view dorsum of propodeum straight, dorsum of petiolar node roundly convex, dorsum of propodeum entirely microreticulate. This new species is also close to A. ceylonicus (Mayr), but mandible with a large apical tooth, a small preapical tooth and followed by 5 indistinct minute denticles, subpetiolar process low and rounded, anterior half of pronotum microreticulate.

Rainfall-runoff modeling is essential for addressing a wide range of issues in urban drainage system design and operation in both scientific research and engineering ***,it has become increasingly attractive to use the smoothed particle hydrodynamics(SPH)method to model rainfall-runoff because of its inherent features such as mesh-free and automatic adaptiveness for wet-dry ***,one of its inadequacies is the lack of an infiltration effect within rainfall-runoff ***,we propose a new methodology that innovatively integrates the infiltration effect into the shallow water equation(SWE)system with the SPH method(SPH-SWE)to represent a more complete rainfall-runoff *** the proposed method,the mass-varied SPH-SWE(MVSPH-SWE)method is enhanced by integrating the infiltration model.A naked area treatment(NAT)method is subsequently proposed to improve the modeling efficiency and *** obtained numerical results are validated using experimental data from the *** results demonstrate that the proposed method is accurate and *** achievements and findings of this study are expected to improve and extend the use of existing hydrological process models.

随着5G建设以及其它各类业务的快速增加,出局光纤芯数和光缆条数也随之增加,现阶段城区很多机房也随之出现了出局管孔不足的情况,给出局管道的规划建设带来了困难。本文以微子孔作为出局管道容量的最小测算单位,从出局管道容量影响因素、公众用户对主干光缆的需求、专线客户对主干光缆的需求、无线网对主干光缆的需求以及中继段光缆需求等对出局管道子孔的需求量进行分析,采用公众用户测算法、汇聚节点数量测算法、光缆条数测算法等方式对出局管道管孔的容量测算进行了分析,得出各类业务纤芯对出局管孔的需求,最终汇总得出出局管道容量的预测模型,给局房出局管道规划提供了建设思路。

The particles of ferric aluminum magnesium hydrotalcite-like compounds (Fe-Al-Mg_HTlc) were synthesized by co-precipitation method. It was found that when n(Fe)/n(Al+Mg+Fe)0.30, Al(OH)3 will emerge; when the molar ratio of Fe/(Fe+Al+Mg) >0.30, the amorphous composition will appear. Hence Fe3+ and Al3+ have no concentration superposition effect on the crystal structure of the samples.

作者： HE Guo-min li shu-ping HUANG Mei-chun Department of Physics Xiamen UniversityXiamen 361005

Structural and electronic properties of RuSi, RuGe and OsSi are investigated by first-principle density-functional calculations based on ultrasoft pseudopotential and generalized gradient approximations for the exchange-correlation functional The bulk moduli for RuGe and OsSi which have not been available from experiments are predicted to be 2.08 and 2.65 Mbar. Though all these compounds with a B20 structure are semiconductors according to the calculation, their band gaps are overestimated compared to those from experiments by a factor of about two.
