Chekhov was an excellent writer of Russian critical realism literature in the 19th century. He successfully shaped the classic character image of Belikov in The Man in a Case,which expresses the criticism of authoritarian society and the deep excavation of human nature. From the two aspects of the analysis of image and causes of characteristic,this paper expounds that putting oneself in a case like Belikov is tantamount to self-isolation and self-destruction. In the face of the external world full of changes,only by constantly innovating and breaking through the constraints can we continue to survive and develop.
Rapid economic progress has led to significant changes in the industrial structure of society,and environmental problems have become increasingly serious. By constructing a coupling model of environment-economy-logistics industry,we measured and analysed the system coupling coordination degree and spatial characteristics of six provinces and one city in East China from 2010 to 2020. The research results showed that the coupling coordination degree of each province and city showed a fluctuating upward trend during the study period,but the overall coordination level was low,and most provinces and cities were still at the stage of barely coordinated development. The spatially positive correlation of the system coupling coordination degree of provinces and cities shows a gradual weakening,and the local spatial variability is large. Therefore,it is necessary to pay attention to green development,improve the coordination level of each province and city,strengthen the interconnection to realize the high-quality coordinated development of environment-economy-logistics industry in each province and city.

The modern media context triggers the reexamination of the previous classic works,highlighting the value of media factors in the construction of literary classics. Although the recently emerged concept of cross-media has not formed a complete theoretical system,it has initially shown a strong explanatory power,or it can be said that the classics have been unable to refuse the investigation of media and cross-media theory in the context of the media age. Cross-media theory should become an important part of the perspective of classic construction. Taking Water Margin as a clue,this paper probes into the rationality of transmedia narrative as the construction of literary classics. The canonization of Water Margin originates from the discovery of the inner aesthetic value of the novel,and is also the result of the construction of external factors. The cross-media communication practices of stories of Water Margin construct the meaning and aesthetic network of the novel,and shape the audience’s understanding of the novel and its classic value recognition.
Wang Wei was a famous poet in the Tang dynasty and an outstanding representative of landscape and pastoral poetry school. The skill of simplicity in Wang Wei’s poetry was formed in the flourishing period of Tang dynasty,which has much to do with his study experience. His skill of simplicity is mainly embodied in the three aspects of poetic language, structure and creation techniques,and plays a driving role in the expression of the emotional connotation of his poems,and also has a profound influence on the creation of later poetry.
From the 10 th to the 13 th century,the northern minorities Khitan,Dangxiang and Jurchen successively established regimes,forming the confrontation period of Liao,Song,Xia and Jin.During this period,Khitans played an important role in connecting the Grassland Silk Road,especially the Western Liao dynasty established by YelüDashi,which promoted the Grassland Silk Road to be further unimpeded,played an important role in the economic and cultural exchanges between the East and the West,and had a wide influence on the Eurasian continent at that time,making the word“Khitan”become the name for China in Central Asia.By reviewing Khitan dynasty’s expansion of the Grassland Silk Road and relevant records in overseas literatures,this paper discusses that the export of silk goods,tea and other products through the Grassland Silk Road,Europeans built the prosperous Khitan （China） image and made the image of China enter the world horizon.This is inseparable from the unique dual system of the Khitan people and the nomadic culture of Nabo.The imprint left by the Khitan people on the Grassland Silk Road is the precious wealth in the history of the Chinese nation.

The mechanism of noise restraint effect of over-damped nonlinear bistable system and the output characteristic of large frequency weak signal passing through nonlinear bistable system are studied in this paper by using the fourth order Runge-Kutta algorithm to analyze the nonlinear Langevin equation. The results of numerical calculation show that nonlinear bistable system has the effect of restraining noise going with large frequency weak signal intensively under the situation of choosing system parameters properly,consequently,the signal-to-noise ratio of output signal is improved evidently. The purpose of extracting large frequency weak signal is achieved by applying this system to detect weak signal from heavy noise background,and this system has been of high applying value.
Marguerite Duras was thought to be the queen in French literature,and she had written many works. With strange life experience and unique writing style,Marguerite Duras had written for herself all her life since she entered the literary world. She always described fictional herself in her works,trying to create a perfect self-image,to seek self-affirmation. This kind of expression may seem narcissistic, but in fact it is deep in the heart of the lack of confidence. The lack of confidence stems from her wonderful but unfortunate life experience,family environment and childhood. From diffidence to narcissism,Duras’ s characteristic gradually changes. The influence of narcissism on people is two-sided. On the one hand,it can lead people to be positive. On the other hand,it will distort people’s personality,which requires people to treat with a dialectical point of view.
