Abstract: As one of the early outbreak areas, China attracted the global news media’s attention at the beginning of 2020. During the epidemic period, Chinese people united and actively fought against the epidemic. However, in the eyes of the international public, the situation reported about China is not optimistic. To better understand how the international public portrays China, especially during the epidemic, we present a case study with big data technology. We aim to answer three questions: (1) What has the international media focused on during the period? (2) What is the media’s tone when they report China? (3) What is the media’s attitude when talking about China? In detail, we crawled more than 280 000 pieces of news from 57 mainstream media agencies in 22 countries and made some interesting observations. For example, international media paid more attention to Chinese livelihood during the period. In March and April, “progress of Chinese vaccines,” “specific drugs and treatments,” and “virus outbreak in U.S.” became the media’s most common topics. In terms of news attitude, Cuba, Malaysia, and Venezuela had a positive attitude toward China, while France, Canada, and the United Kingdom had a negative attitude. Our study can help understand China’s image in the eyes of the international media and provide a sound basis for image analysis.

Strategic Study of CAE 2005, Volume 7, Issue 10, Pages 51-55

Abstract:

A conception of “un-stressing concentration” anti-fatigue for ultra-high strength steel 300 M has been investigated. The compress stress field and cell structure with high density dislocation were formed in surface layer of specimens with the surface integrity machine, shot peening, hole extrusion and screw rolling strengthening, by which the crack initiation was changed to the subsurface from surface, crack propagation was thwarted, fatigue limit at the place of stress concentration were returned to a approximate to the innate fatigue limit of 300 M steel and “un-stressing concentration” surface integrity condition was resulted. This conception of “un-stressing concentration” anti-fatigue was described as a comprehensive equi-fatigue strength, which was equal approximately to the innate fatigue limit of 300M steel, encirclement on the constructure surface case.
