Using singularity theory, the bifurcation behavior of these solutions with respect to the excitation amplitude and frequency are investigated in detail, respectively.The results show that the universal unfolding with respect to the excitation amplitude possesses codimension 3. The transition sets in unfolding parameter plane and the bifurcation diagrams are plotted under some conditions. Additionally, it has also been proved that the bifurcation problem with respect to frequence possesses infinite codimension. Therefore the dynamical bifurcation behavior is very complex in this case. Some new dynamical phenomena are presented, which are the supplement of the results obtained by Sun Liang et al.展开更多

In the future, Chinese consumers can only go to Japan counters to buy. However, the brand will fully switch to Tmall International and launch the e-commerce platform. The reason for this is that the products selling on counters are currently one year later than Japan and other countries, which is not conducive to the consumer experience.展开更多

The Mill of On Liberty may seem to be a pluralist who tends to prefer difference per se to goodness of a uniform pattern, many-sidedness to conformity, and eccentricity to mediocrity. This paper seeks to challenge this argument by paying close attention to the text. It argues that the Mill of On Liberty was far from a single-minded pluralist. Two divergent positions are found throughout his reasoning: one is a pluralist idea that an individual's own plan of life is the best, no matter how base or licentious it might be; the other is the belief that there exist a limited number of ideal ways of life which define what the good life is. The two positions are, if not mutually exclusive, at least in important aspects indicative of some profound tension at the center of Mill's thought.展开更多
