“The Law of Life”is one of Jack London’s representative works,depicting the story of an elderly Native American abandoned by his family,alone and waiting for life to fade *** paper,based on narrative theory,aims to explore how the author employs narrative techniques to present the image of the old man in the short *** narrative techniques of dual focalization and dual narrative timelines in the text demonstrate the abandonment of the old man’s homeland and his inescapable death under a naturalistic view of life and reflect a desolate life picture of resignation towards death under naturalistic determinism,depicting a grim elderly world under the naturalistic concept of“survival of the fittest.”Studying this short story helps us reflect on the living conditions of the elderly and provides insights into how to better care for the elderly population amid the global trend of aging.

Comprehensive Evaluation Research of Sustainable Utilization of Regional Water Resources

2.07中国生物医学工程联合学术年会

作者： Jian Zhu Institute of Modern Physics, School of Science xi''an Jiaotong university, xi''an 710049, china

＜正＞Both core and embedding medium dielectric constant can influence the optical absorbance of gold nanoshells. Numerical calculations based on Drude model and quasi-static theory indicated that, there are two absorbance peaks corresponding to plasmon resonance take place. The longer wavelength peak is sensitive to the dielectric constant. When the core dielectric constant is fixed at 5.4, with increasing the dielectric constant of surrounding medium from 1.0 to 9.0, the longer wavelength peak red shift linearly and increase rapidly first and then decrease slowly. When the surrounding’s dielectric constant is fixed at 1.8, with increasing the core dielectric constant from 1.0 to 9.0, the longer wavelength peak red shift nonlinearly and decrease nonlinearly.

This paper is devoted to investigating neutron transport in nonhomogeneous slab with generalized boundary conditions and anisotropic scattering-fission kernel. The time dependent equation and the corresponding transport operator A are discussed in the space of continuous functions. Some aspects of the spectral properties of A (e.g.,the properties of Pas(A) and the dominant eigenvalue of A, etc.) are considered and the exist ence- unique nes s of t he of as s ical t line dep endent so lut ion is obt anied. Furl hermore, an asymptotic expansion (under the maximum norm) of the time dependent solution is givenand the asymptotic behavior is studied.
