In the early days of the founding of the People’s Republic of China,in order to restore the national economy as soon as possible,the Communist Party of China carried out maintenance and repairs on the railways that caused serious damage to transportation tasks through war-torn smoke,and carried out large-scale railway construction.However,in the course of operation,railway safety accidents occur frequently due to outdated equipment,low quality of staff,lack of rules and regulations,vandalism,and various natural disasters.In the face of severe conditions,the railway authorities summed up the accidents and learned the safety of the railways,so that the railway transportation industry,which started after the founding of the country,was gradually on the right track,and laid a solid foundation for the safe development of the railway industry. 展开更多

IT is sometimes hard for foreigners in China to express to their friends and family back home what exactly it is about their host country that keeps them so fascinated. Whether it is the endless array of dumplings, hot-pot nights with friends, or the tea traditions that instantly put you at ease, I would bet China's food culture is at the top of many people's list. 展开更多

Based on data of number of fog and haze days in Baoji City from 1981 to 2013,the changing trends and mutation of number of fog and haze days in Baoji over the past 33 years were analyzed by using trend coefficient,tendency rate,linear regression analysis,anomaly percentage,Mann-Kendall mutation test and sliding t test.The results showed that during the 33 years,the number of fog and haze days in Baoji declined by 16.253d/10 a,and there was a cyclical turbulence every 6,15 or 28years.The frequency of fog and haze weather was the highest in winter,followed by spring and autumn,while it was the lowest in summer.According to the anomaly percentage of the number of fog and haze days in 12 months during 1981-2013,the anomaly percentage changed most greatly in July,followed by September,October,April,May,June,August,February and March,but it fluctuated less greatly in January.The number of fog and haze days from 1981 to 2013had obvious mutation trends in a single year and a single season,and mutation types are different. 展开更多

Then it analyzes address usage. After describing the factors above, this report makes several assumptions and gets the result of IPv4 address's running out day in China. Conclusion is in 2006 IPv4 address in China will run out and IPv6 related applications are to be on the stage. 展开更多

As China opens to the world, Chinese people are embracing the Western world's holidays. Christmas, Valentine's Day and Halloween are all growing in popularity, as the commercial aspects of these celebrations find an audience. Young people say they feel increasingly detached from traditions associated with age-old Chinese festivals, such as Spring Festival, which starts January 29 this year and marks the lunar New Year. But Spring Festival isn't going anywhere yet, and this week the country heads home en ... 展开更多
