Especially the young, born after the 1980s, will play an important part in the future housing market. So it seems quite urgem to effectively satisfy the housing needs of young people. Massive research and practices indicate that the housing industrialization conserves the environment, improves quality and reduces cost of housing and is among the most effective ways to boost sustainable development of housing industry. The main objective of the paper is to discuss how to meet the growing housing demands of the young and concludes that housing with recreation, sports and other ancillary facilities will be better fit to the young to rent or to own. Furthermore, an analysis of the Chongqing housing market potential of young people＇s wish to rent or to purchase satisfactory housing demonstrates that some real estate investors may be failing to exploit serious opportunities that could arise from providing service to the young. And this case study of meeting the changing housing needs of the young may help accelerate the process of housing industrialization in Chongqing as well as providing a useful study concerning housing industry.展开更多
Vanadium - bearing stone coal is a new resource of vanadium. V in stone coal mainly exists in three oxidation states: 7.84% V(III), 72.08% V(IV) and 20.08% V(V).

V in stone coal mainly exists in three oxidation states: 7.84% V(III), 72.08% V(IV) and 20.08% V(V). The change and distribution of valency during oxidizing roasting shows that organic matter in the coal determines the valency at low temperatures. At about 450°C, V(III) is completely oxidized to V(IV); above 500°C, temperature is the most important factor for the oxidation of V. At 700-1000°C, 92% of V in the coal has been oxidized to V(V). At higher temperature, no more oxidation of V takes place, equilibrium being established. The role of NaCl in the recovery of V2O5 from the coal is discussed. The best conditions for roasting are an oxidation-chlorination atmosphere, temperature 800°C for 30 minutes, ore:NaCl = 100:10, ηroast reaching 90%.展开更多

During the 13th Five-Year Plan period (2016–2020), China has made great achievements in the three major aspects of targeted poverty alleviation through industrial development, development of special rural areas, and equalization of urban and rural infrastructure and basic public services. In addition, the important experience of multi-agent participation, multi-mode guidance, and multi-line promotion has been accumulated in the individual, regional and urbanrural dimensions. However, there remain some deficiencies, such as low policy efficiency, poor matching ability, and prominent structural problems. At the beginning of the 14th Five-Year Plan (2021–2025), the task of enriching farmers through sharing has been faced with many challenges, such as major changes in the focus of poverty governance, greater numbers of restraints on the development of special rural areas, and heavy responsibilities of equalizing urban and rural infrastructure and basic public services. Therefore, it is necessary to acquire a profound understanding of the new development concept, and to continuously enrich farmers through sharing in terms of accelerating the improvement of the institutionalized poverty reduction system in the new era, actively building a green development system of agriculture and animal husbandry in special rural areas, and striving to create a fair and complementary urban and rural infrastructure and basic public service system.展开更多
