Changes in China's social and economic structures, cultural scenes and social operations are revolutionary. The Chinese people, who account for one fifth of the human race, are working hard to bring about a national reiuvanation.展开更多

One of the objectives set at the 16th National Congress of the Communist Party of China (CPC) for building a well-off society in all aspects is to construct a harmonious society. A livable city is one of the most important aspects of a harmonious society. Being so called is closely associated with the living quality of the people in that city and one of the important yardsticks to measure the achievements of China's reform and development. As a development objective, a livable city should have its standards. However, different countries have advanced their standards differently for judging a livable city. There are still not international unified standards. With the passing of the times, the building of a standard system for a livable city is of increasing value both theoretically and practically. In January 2005, the "General City Planning for Beijing Municipality (2004-2020)" was approved by the State Council Beijing was the first to make "livable city" one of its objectives. This will have a significant impact on urban and economic development in the Chinese capital and will have a profound impact on other areas in the effort to build livable cities. In view of the actual conditions of the development of cities in China, this paper has advanced such standards as economic development, social harmony, and amenities for judging whether a city is a livable city, and made empirical analysis of the development of livable cities in China.展开更多

The bubbling and fast fluidization issues were emphasized so that the future offluidization research can be discussed among scientists and engineers in a wider perspective. The first cycle of fluidization research was started in the early 1940s by an initial stage of phenomenology. The second stage of structural studies was kicked off in the early 1950s with the introduction of the two phase theory. The third stage of essential studies occurred in the early 1960s in the form of bubble hydrodynamics. The second cycle, which confirmed the aforementioned three stages closed at the turn of the century, established a general understanding of suspension structures including agglomerating fluidization, bubbling, turbulent and fast fluidizations and pneumatic transport; also established powerful measurement and numerical simulation tools.After a general remark on science, technology and society issues the interactions between fluidization technology and science are revisited. Our future directions are discussed including the tasks in the third cycle, particularly in its phenomenology stage where strong motivation and intention are always necessary, in relation also to the green reforming of the present technology. A generalized definition of 'fluidization' is proposed to extend fluidization principle into much wider scientific fields, which would be effective also for wider collaborations.展开更多

文摘In recent times, China has shifted its position from the pursuit of pure GDP to that of humanistic GDP, environmental GDP, and to the unified harmonious development of population, resources, and environment.
