56 ground motions of the bedrock and surface are selected from 28 stiff sites ( site class I and site classⅡ) of the KiK-net station．The peak acceleration, response spectra and shear strain of actual hard sites are calculated by using SHAKE2000 and LSSRLI-1. The similarities and differences between SHAKE2000 and LSSRLI-1 and their differences from measured records are analyzed. It provides a ba...

Thematic structure, an important factor for textual metafunction, plays a significant role in inspecting and promoting the textual coherence. With a theoretical statement of Thematic theory and TP patterns, this paper proposes the feasibility of the Thematic Operational Approach in the teaching of college English writing. This approach is proved to not only strengthen students’ application awar...

As a grammatical device, Theme-Rheme structure plays an important role in organizing and analyzing discourse. Theme Progression patterns (hereinafter called TP patterns) are significant method of the analysis of textual cohesion and organization. Based on linguist Danes’ theory about TP patterns, this paper tries to present a contrastive analysis of the texts of consecutive interpretation in En...

A constitutive model based on two–dimensional unstructured Galerkin finite volume method (GFVM) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. The developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...

The optical second harmonic generation from a thin magnetic film on a nonmagnetic substrate is theoretically investigated for both sand p-polarized incident light. The contributions of lattice misfit strain as well as of misfit dislocation strain to the second-order nonlinear optical susceptibility are described using a nonlinear photoelastic tensor, together with the contribution of magnetizat...

Reconstruction of acoustic, seismic, or electromagnetic wave speed distribution from rst arrival traveltime data is the goal of traveltime tomography. The reconstruction problem is nonlinear, because the ray paths that should be used for tomographic backprojection techniques can depend strongly on the unknown wave speeds. In our analysis, Fermat's principle is used to show that trial wave speed...
