The historical starting point requires the study of ancient Chinese capitals to abide by rigid academic principles and must be based on historical facts. Contemporary vision refers to the obligation to contribute to contemporary society and civilization through ancient Chinese capital research. World insight expresses our need of an integral and systematic concept to correctly assess the historical status and role of ancient Chinese capitals in the larger context to unveil the unique cultural values and historical significance of ancient capitals across China. Chengdu is an ideal case for us to explore new research approaches from the above three aspects.展开更多

It is intellectual capital. Because intellectual capitals increase GDP of nations, and create wealthfor nations. ICs have accumulated knowledge, and ICs make innovations for company via this knowledge. Forexample, American economy has full of ICs, corporate CEOs. CEOs make country rich. CEOs are intellectualcapital. For example, Steve Jobs created smart phone, and Apple becomes no.1 in markets. Therefore, ICs(corporate CEOs) make a country richer. Intellectual capital is related with human resource management. Therefore,a country make investment to human resource management to create wealth of nations and intellectual capitals.展开更多

In this study, we attempt to use the random walk model to fit the annual precipitation in 49 European capitals from 1901 to 1998. At first, we used the simplest random walk model to fit the precipitation walk, which is the conversion of recorded precipitations into ±1 format, and then we used a more complex random walk model to fit the recorded precipi-tations. The results show that the random walk models can fit both precipitation walk and re-corded precipitation. Thus this study provides a model to describe the precipitation patterns during this period in these cities.展开更多
