SFG data and orientation analysis The theoretical data analysis of SFG spectra generated from the air/liquid interface has been described elsewhere.1 The SFG intensity I() can be expressed as a function of the second order susceptibility 2-4 3 2 2 8 sec (2) 2 I() 3 | eff | I(1)I(2 ) (1) c0 n1()n1(1)n1(2 ) Where , , and are the frequencies of the SF signal, visible, and IR laser beam, respectively. n1(i ) is the refractive index of bulk medium i at the frequency of i , I() is the intensity of the SFG signal or the input laser beams, c0 is the speed of light in vacuum, is the incident or reflection angle of the ith light beams from the surface normal, which is defined as the z axis in the laboratory coordinates system (x, y, z), and (2) is the effective macroscopic second-order susceptibility. (2) depends on eff eff the experimental geometry and polarizations. In the polarization dependent SFG experiments, there are three typical polarization combinations commonly used in the (2) SFG studies, namely, ssp, sps and ppp. eff under these three polarization combinations can be expressed as 2, 4 (2) eff ,ssp Lyy ()Lyy (1)Lzz (2 )sin 2 yyz (2) eff ,sps Lyy ()Lzz (1)Lyy (2 )sin 1 yzy (2) eff , ppp Lzz ()Lxx (1)Lxx (2 )sin cos 1 cos 2 zxx (2) Lxx ()Lxx (1)Lzz (2 )cos cos 1 sin 2 xxz Lxx ()Lzz (1)Lxx (2 )cos sin 1 cos 2 xzx Lzz ()Lzz (1)Lzz (2 )sin sin 1 sin 2 zzz where Lii () is the tensorial Fresnel factor as shown below: 2n1()cos Lxx () n1()cos n2 ()cos 2n1()cos Lyy () (3) n1()cos n2 ()cos 2 2n2 ()cos n1() Lzz () ' n1()cos n2 ()cos n () in which is the refracted angle and n' () is the effective refractive index of the interfacial layer.

When the IR frequency is resonance to the molecular vibrational transitions, the second order molecular polarizability is described as the following (2) (2) (2) q NR (5) q IR q iq (2) (2) where NR is the non-resonant contribution, q ,q , q are the strength factor tensor, resonant frequency and damping constant of the qth vibrational mode, - respectively. For SCN anion which can be treated as Cv symmetry, the nonzero second-order hyperpolarizabilities are aac bbc , ccc . Thus the macroscopic susceptibility tensors under three different polarizations can be given in the following 1 N (1 r) cos (1 r) cos3 xxz yyz 2 s ccc 1 N (1 r) cos cos3 (6) xzx zxx yzy zyy 2 s ccc N r cos (1 r) cos3 zzz s ccc where r is the ratio of aac / ccc , which can be determined through the polarized Raman measurements. is the tilt angle of SCN- transition dipole (CN stretching) from the surface normal. By using the SFG intensity ratio method, the orientational parameter D= cos / cos3 can be determined. With orientational parameter D known, the relative number of SCN- anions adsorbed at the air/water interface can be calculated from the following expression 2 2 2 I() | eff | Ns | r( ) | (7) r( ) is the orientational function related to the orientational parameter D.5, 6 The SFG intensity is proportional to the product of the square of the surface density and the orientational function, and their contributions can be easily separated through the polarization SFG analysis. 2.

Li Nationality’s dwellings space and model have their peculiar vantages including the ancient wisdom of sustainable environmental protection and respecting natural world. Li Nationality adopted the idea of building a boat to construct houses and organized their own families before 4000 years ago and the houseboats contained typical characteristics of simple, saving materials and making good use of the old boats . However, with the modern cultures influence of Han Nationality, more Li people is giving up their traditional houseboats. The only reserved village which possesses traditional houseboats is Baizha in the Dongfang City of Hainan Province. Hainan Province government and researchers are trying to protect the related cultures and houseboats style architecture by moving them into the scenic area or introduce more tourists to visit village having houseboats to increase the income of Li Nationality and make them adapt themselves to modern economic society based on reserve traditional life-style. Step 1 is digging historical and cultural information in Li Nationality, their fairy stories, religious faith and folk songs, step 2 is applying all those materials to intangible cultural heritage list and getting enough subsidiary funds from governments, step 3 is organizing researchers and architects to visit village, step 4 is attracting more tourists to visit it, reserving this traditional architecture style based on cyclic economy.

  • Analysis of Influencing Factors of Migratory Tourists Behavior in Sanya
    2018 1st International Conference on Education, Art, Management and Social Sciences (EAMSS 2018) Analysis of Influencing Factors of Migratory Tourists Behavior in Sanya Gong Huiqin Tourism Management College, University of Sanya, Sanya, Hainan, China, 572002 Keywords: "Migratory bird" tourism, influencing factors, tourist behavior characteristics Abstract: In recent years, "migratory bird" tourism has developed rapidly, especially in coastal coastal resorts. It is also favored by people. As one of the famous coastal tourist cities in China, Sanya has become the main destination for many elderly migratory tourists. However, as the tourism of elderly migratory tourists in China is at a preliminary stage of development, the development policy for the elderly of migratory tourists is not perfect. Therefore, this paper takes the elderly migratory tourists in Sanya as an example to analyze the current and objective factors affecting the decision-making behaviors and consumption behaviors of migratory tourists. It finds out the current problems in the Sanya tourism market and provides advice for Sanya tourism companies to develop “migratory bird” tourism products and develop targeted marketing strategies. With the rapid development of China's tourism industry, people's material life is becoming more and more abundant, and the level of consumption is getting higher and higher. More and more ordinary people choose to travel abroad to enrich their lives. As a new model of tourism and old-age care, "migrant bird tourism" has gradually been loved by the elderly in recent years. The concept of migratory bird-age care is: tourism, living and living. Retired old people have relatively more time and discretionary income, and are conditionally changed according to different seasons, ecological environment and regional climate.

The significance and functions of the education in the mother tongue dialect to the growth of human should not be underestimated. However, in the current education system in China, what people accepts since childhood is the education in mandarin. To the university, only the students majoring in Chinese in some colleges and universities have the opportunity to contact the knowledge on the dialect, most people have not been educated in dialect. The serious absence of the education in dialect is the main cause of the ecological crisis of Chinese dialects. Teenagers are the main force carrying a dialect culture, which is also the special group of language users. How often they learn and use a dialect is crucial to its future development. Based on the investigation of the language use and education in dialect of the teenagers in the Jun Dialect area of Hainan Island, this paper analyzes the current situation of the development of Jun Dialect and puts forward the development direction of education in dialect in the future.
