| 2 | Optimal Harvesting and Stability for a Predator-prey System with Stage Structure显示文摘The dynamics of a predator-prey system, where prey population has two stages, an immature stage and a mature stage with harvesting, the growth of predator population is of Lotka-Volterra nature, are modelled by a system of retarded functional differential equations. We obtain conditions for global asymptotic stability of three nonnegative equilibria and a threshold of harvesting for the mature prey population. The effect of delay on the population at positive equilibrium and the optimal harvesting of the mature prey population are also considered. | Xin-yu Song, Lan-sun ChenDepartment of Mathematics.

| 6 | Principle of Interaction between Plastic Volumetric and Shear Strains and the Constitutive Model for Geotechnical Materials显示文摘Here is proposed the principle of interaction between plastic volumetric and shear strains, revealing the main origin of generating the complexity and variety of deformations for geotechnical materials. Here are also explained the manners of the interaction between plastic volumetric and shear strains and the conditions of generating shear dilatancy. It is demonstrated that dependency of the stress path exists and is a combination of effects of this interaction. According to this principle, it is theoretically proved that the space critical state line exists, and is unique and independent of the stress history. Based on this principle, the constitutive models that are able completely and accurately to characterize the basic behavior features for geotechnical materials have been constructed within the framework of thermodynamics. What is determined is a general expression of the constitutive relation as well as the inequality of the dissipative potential increment for obeying the second law of thermodynamics. | Wang Jingtao(1.Department of Architectural Engineering, Xinyang Normal University, Xinyang 464000, Henan, China 2.School of Civil Engineering and Mechanics, Huazhong University of Science and Technology, Wuhan 430074, China) | 2007 | 工程科学(英文版)2007，5，2： | 2 |

| 11 | The Principle of Interaction between Plastic Volumetric and Shear Strains for Unsaturated Soils显示文摘The principle of interaction between plastic volumetric and shear strains for rock and soil has been extended to the field of unsaturated soils.Two new interactions of suction-plastic volumetric strain and pore air pressure-plastic volumetric strain appear in the unsaturated state of a soil except the interaction between plastic volumetric and shear strains.It is very important to find that the suction possesses a dual property,which is the origin of generating its special functions.Thereby the effect of the suction on volumetric strain includes two opposite aspects.By means of this property of suction,the physical significance of effective stress parameter,effects of suction on volume change and preconsolidation pressure,and the mechanism of collapse upon wetting all can be explained.In addition,it is theoretically proved by application of this principle of interaction that the critical state line for unsaturated soils exists,and is unique and independent of the stress history. | Wang Jingtao1,2(1.Department of Architectural Engineering,Xinyang Normal University,Xinyang,Henan,464000,China 2.School of Civil Engineering and Mechanics,Huazhong University of Science and Technology,Wuhan,430074,China) | 2007 | 工程科学(英文版)2007，5，3： | 1 |
