媒介时代的文学形象媒介化

媒介产品的大量生产是以文学形象为中心的。媒介时代的文学形象媒介化包含两个层面:一是媒介的文学形象化,即符号媒介和传播媒介的文学形象化,表现为传播媒介注重利用文学作品和文学形象来传播信息、吸引受众,还表现为新闻作品的文学化和新闻事物、新闻人物、新闻场景等的文学形象化;二是文学形象的媒介化,即文学文本、文学形象的传播媒介广泛化,表现为文学作品越来越以能否改编为影视作品为写作标杆,文学形象转变为影视形象才能大众化,还表现为指文学作品的传播越来越依赖媒介的运作,越来越倚重文学形象的传播。文学形象媒介化对文学和文学形象而言有利有弊。     

从孙悟空看媒介时代文学形象的增殖

媒介时代的文化艺术生产渐渐形成了一种以文学形象为根源性、共同性因素的相关艺术文本的生产模式,即文学形象在异质媒介中的增殖模式。指出孙悟空形象除了在文学、影视、戏曲、游戏等作品文本的多重媒介中增殖,还作为文化形象、商业形象或娱乐形象出现在文化产品、旅游产品或游乐产品中。文学形象的增殖是文学艺术作品生产的内驱力,促使文学形象增殖的原因包括媒介伸手、形象长腿和经济效益的驱动。

3D numerical simulation in acoustic-elastic coupled media with staggered-grid finite-difference method

Acoustic-elastic coupled media is often encountered in most marine explorations, and accurate simulation of acoustic-elastic coupled media is of great significance. At present, the study of acoustic-elastic coupled media still assumes that the solid of the acoustic-elastic coupled media is isotropic, but this assumption is not in accordance with the actual situation. In this paper, we derive the solid media of acoustic-elastic coupled media from isotropic media to anisotropic media, and propose an acoustic-elastic coupled medium based ontransverse isotropic media with vertical symmetric axes(VTI) to improve the accuracy of forward modeling. Based on the relationship between the Thomsen parameter and the coefficient matrix of the anisotropic elastic wave equation, we transform the Thomson parameter into a velocity model with anisotropic properties. We use a staggered grid finite difference method to simulate the propagation of a wavefield in a three-dimensional acoustic-elastic coupled media. We obtain the snapshots of the wave field when the solid of the acoustic-elastic coupled media is an isotropic medium and a VTI media. When the solid of the acoustic-elastic coupled media is considered VTI media, we can observe the qP wave and qS wave that cannot be observed in the isotropic medium from the wave field snapshot. We can also find that the seismic records obtained by the method we use are more realistic. The algorithm proposed in this paper is of great significance for high-precision ocean numerical simulation.     

Comparison of finite difference and pseudo-spectral methods in forward modelling based on metal ore model of random media

With more applications of seismic exploration in metal ore exploration,forward modelling of seismic wave has become more important in metal ore.Finite difference method and pseudo-spectral method are two im-portant methods of wave-field simulation.Results of previous studies show that both methods have distinct ad-vantages and disadvantages:Finite difference method has high precision but its dispersion is serious;pseudo-spectral method considers both computational efficiency and precision but has less precision than finite-diffe-rence.The authors consider the complex structural characteristics of the metal ore,furthermore add random media in order to simulate the complex effects produced by metal ore for wave field.First,the study introduced the theories of random media and two forward modelling methods.Second,it compared the simulation results of two methods on fault model.Then the authors established a complex metal ore model,added random media and compared computational efficiency and precision.As a result,it is found that finite difference method is better than pseudo-spectral method in precision and boundary treatment,but the computational efficiency of pseudo-spectral method is slightly higher than the finite difference method.

从“文学终结论”析文学困境之原因

在现代媒体深深介入文学领域并困绕既往的文学习惯,造成文学困境的时候,希利斯.米勒提起的“文学终结”论无疑引起人们思想上的波动,并让人深省造成文学困境的原因。事实上,造成困境是多种力量合力的产物,而不能仅仅归源于现代媒体,文学创作者与文学研究者对大众群体文学接受视野某种程度上的漠视,也负有不可推卸的责任。     

Evaluation and Influence Factor of Green Efficiency of China's Agricultural Innovation from the Perspective of Technical Transformation

Agricultural innovation is important for the green transformation of agriculture. Based on the perspective of technology transformation, this paper builds a theoretical analysis framework and evaluation index system for green efficiency of agricultural innovation,and discusses the evolution laws and influencing factors of the green efficiency of China's agricultural innovation from 2005 to 2017 utilizing the DEA model, Malmquist index, and Tobit regression analysis. The results show that: 1) The overall green efficiency of China's agricultural innovation is not high, the green efficiency of agricultural innovation in eastern China is mainly driven by pure technical efficiency, while that in central and western China is mainly driven by the scale efficiency. The green efficiency of agricultural innovation shows significant spatial differences, and the low efficiency and relatively low-efficiency regions moved to central and southeastern China. 2) Technical progress is the main force affecting the change of green total factor productivity of China's agricultural innovation, seeing a trend of decrease followed by an increase. Pure technical efficiency and scale efficiency exhibit an increasing-decreasing trend, and gradually transform into key factors that restrict the improvement of the green total factor productivity of agricultural innovation. 3) Agricultural technologies' diffusion, absorption, and implementation are three influencing factors of the green efficiency of agricultural innovation. The local level of informatization, the number of agricultural technicians in enterprises and institutions, average education level of residents, and the level of agricultural mechanization have positive impacts on the promotion of the green efficiency of agricultural innovation, promoting the diffusion, absorption and implementation of agricultural innovation technology can significantly improve the green efficiency of agricultural innovation.     

Full-wave synthetic acoustic logs in porous media

In order to investigate the permeability of porous media,it is necessary to figure out the property of wave propagation in this medium. The authors calculated the full waveforms and the 2-dimensional spectrum of fluid saturated porous media,analyzed the wave propagation characteristics of different permeable stratums. From the theoretical acoustic pressure waveform received at the well-axis and the 2-D spectrum it is revealed that longitudinal-,transverse-,Stoneley-,pseudo-Rayleigh-,longitudinal mode-and transverse mode waves are different in characters in various permeable strata. Stoneley wave is sensitive to the change of permeability,and its frequency range and amplitude attenuation are influenced by permeability.
