The nonrelativistic energies for lithium isoelectronic sequence 1s~2ng and1s~2nh (n = 5,6,7, and 8) states from Z = 3 to 8 are calculated by using a full core pluscorrelation (FCPC) method with multiconGguration inter...The nonrelativistic energies for lithium isoelectronic sequence 1s~2ng and1s~2nh (n = 5,6,7, and 8) states from Z = 3 to 8 are calculated by using a full core pluscorrelation (FCPC) method with multiconGguration interaction wave functions. Relativistic andmass-polarization effects on the energy are evaluated as the first-order perturbation theory. Ourpredicted excitation energies are compared with previous experimental results in the literature.展开更多

The interrelation between the coastal zone and the preference structure of visitors form a desired tourism setting and a hospitable destination in which environmentally friendly practices dominate the tourism aspects. Conjoint analysis was used with a purpose of eliciting respondents＇ preferences and answering questions concerning the features that compose a sustainable tourism product. In the survey, 16 proposed combinations of tourism characteristics were rated by 1,433 respondents. The three most preferred factors of the proposed tourism product were the accommodation factor, the sea activities factor and the fishery tourism factor with averaged importance scores 27,351,22,900 and 2 1, 13 1, respectively.展开更多

This paper tries to examine inbound tourism development in China in the last decade and analyze inbound tourism's satisfaction of their travel experience with tourist attractions, facilities, services and price by an empirical study based on the investigation of Lanzhou, Wuhan, Guangzhou, Shanghai and Beijing. This paper discusses the demographic characteristics of visitors from Hong Kong, Macao and Taiwan, US, Korea and Japan by surveying a sample of 528 visitors in fi ve different cities. The survey showed that four provinces/autonomous region in western China ranked the top 10 popular destinations. Chinese natural landscape, culture and food were highly regarded by the tourists. At the same time, tourists expressed less satisfaction with tourist language convenience, tourist facility and nightlife in China. It was also found that only 7.4% of the tourists thought travel in China was far more than what they had paid, that 6.5% regarded they got what they paid for, and that 34.9% thought the travel cost was reasonable. Most tourists were satisfi ed with their travel experience in China; many of them would like to return to China and would like to recommend China. For the sustainable development of tourism, Chinese tourism authorities should strengthen the construction, propaganda and management of scenic spots, improve tourist facility and tourist education, especially language convenience, and strengthen the supervision of tickets, souvenir and hotel price.展开更多

It is also the needs of establlshing socialist harmonious society in China. It is an arduous systematic project in ethnic group regions of China to realize economic and sodal sustainable development,promote the harmony between man and nature andrealize the coordination among the economic development population, natural resources and envinonment To develop ecosystem construction and the green indutry well is the basic path to realize the above goals. Huanren Manchu Autonomous County in Liaoning Province is abundant in forests, especially local products, medicinal materials, tourism resource, water resources and culotte resources. In order to develop its ecosystem, the strategies should be focused on enhancing protection consciousaess, brand consciousness, science and technology consciousoess and market consciousness.
