There are five earthquakes with Ms ≥5. 0 in the Qianguo earthquake swarm, with magnitudes of Ms 5. 5, Ms 5. 0, Ms 5. 3, Ms 5. 8 and Ms 5. 0. In this study, the far-field seismic radiated energy characteristics of the earthquakes are compared based on the source spectrum and the ground motion spectrum of the earthquake swarm. The ground motion spectrum of the five earthquakes at Changchun seismic station （CN2）, which is the national standard station, is first investigated with the recorded ground motions, and then the far-field seismic radiated energy is calculated and combined with the relationships of the source spectrum to describe the variable characteristics of the Qianguo earthquake swarm. Research results indicate that the second earthquake （No. 2） with Ms5. 0 is the key event of the earthquake swarm, which occurred on October 31, the same day following the first Ms5. 5 earthquake （No.l）. In fact, the magnitude of event No. 2 decreased compared to event No.l, which did not agree with its large far-field seismic radiated energy. It needs to be pointed out that event No. 2 was the turning point event of the Qianguo earthquake swarm, as being a significant transition before the largest Ms5. 8 earthquake.展开更多

It exemplified the wisdom of the working people. The knots have the beauty of plainness and nature. Applying it in modem decoration would give the Modem decorative art personality and all kinds of form are available. The two parts would interact and help each other forward. Through the research, this paper analyzed the styles and features of Chinese knot. As well as the development and application of Chinese knot in Modem decorative art. In order to make the theoretical bases, for the sake of inheriting and continuing fine folk arts.展开更多

In order to explore factors that hinder telework adoption in China, this study addresses which individual or environmental factors affect people＇s decision to adopt telework and especially focus on the perception of and attitude toward telework （lllegems et al. 2001） as one of the key factors for telework implementation. By identifying variables that may have an impact on the attitude towards telework acceptance based on the literature reviews, the author collected the data of employees/managers from Chinese organizations through the online survey in 2014. The analyses show that there is statistically significant difference in attitude between men and women, employees and managers, and different marital status and commuting time groups. The findings suggest that China-specific cultural and environmental factors impede the adoption and/or acceptance oftelework.展开更多
