According to the old surface coating process of European and American furniture, the surface of modified poplar is first differentiated pre-treatment, and then the bottom color modification and material color modification are respectively applied to the modified poplar after the surface differentiation treatment. The visual physical quantity and physical and chemical properties were measured and compared with mahogany, which is commonly used in old furniture in Europe and America to explore the effect of colorants and coloring steps, as well as different surface pretreatments on the coloring effect. Finally, it is concluded that continuous coloring operations can narrow the difference in brightness and red color value in the coloring layer of modified poplar and mahogany. Continuous coloring operations increase the difference between the yellow-green color values of modified poplar and mahogany. Therefore, the coloring difference between modified poplar and mahogany was affected by the colorant and coloring steps. Through color accumulation, the gap between the two in the target color coloring effect can be reduced, thereby reducing the difference between the coloring effect of modified poplar and mahogany.
As a large-scale landscape region, Tibet has ubiquitous and decentralized tourism resources, unique landscape, and layout of transportation routes. The various natural conditions such as terrain, altitude, and climate make tourist flows in Tibet completely different from other regions, especially for group and self-guided tours. This study collected data on group tour and self-guided tour from popular tourism websites, and combined social network analysis to explore the network structure characteristics and organizational models of tourist flows to Tibet, providing a theoretical reference for the optimal organization of Tibet tourism destinations. The study found that the tourist flow into Tibet is characterized by overall agglomeration and hierarchical differentiations. The nodes are not closely connected and the core-periphery structure is obvious. Group tour is strongly dependent on hub nodes and traffic, and self-guided tour covers a large area. Group tour and self-guided tour modes present "destination area loop" and dispersion features, respectively, and the phenomenon of crossing administrative regions in the compact network segment is prominent and largely controlled by the main traffic routes. The difference between tourist flows of group tour and self-guided tour reflects the joint influence of terrain, altitude, transportation, tourism resource distribution, and consumption ability. It is the result of spatial decision-making of individuals and groups under different tourism motives and the comprehensive effect of multiple factors, and has influenced the development of tourism transportation layout, tourism product combination, and regional tourism cooperation in Tibet. The research results provide a reference for understanding the flow and movement patterns of tourists entering Tibet for group tour and self-guided tour, and it can provide a theoretical guidance for the optimization of tourist route design and collaborative planning of tourist destinations in Tibet.
<p>Relevant surveys show that in recent years, with the improvement and optimization of the level of economic development, the public’s attention to catering has been increasing, which has effectively promoted the development and implementation of food safety management in my country. In this process, a large number of researchers have conducted in-depth analysis and exploration of related work based on the current development of my country’s food safety management team, aiming to further improve and optimize the comprehensive level of food safety management in order to work for my country’s food safety. The improvement of overall quality provides a new impetus. Based on a large amount of data, this paper analyzes and discusses the shortcomings of my country’s food safety management at this stage. At the same time, the researchers put forward corresponding optimization strategies based on their own work experience, aiming to further realize the comprehensive quality of the food safety management team. The improvement and optimization of food safety in China will then provide impetus for the development of my country’s food safety work.</p>
The target that reducing by 17% of carbon dioxide emission per GDP is regarded as constraint indicator into our national economic and social development planning during the twelfth five-year demonstrates the responsible attitude to the global climate change. The article establishes the evaluation system of carbon reduction. Adapted to factor analysis and clusting, it reflects the religion difference of carbon reduction potential and makes the relational classification. Setting targets of carbon reduction in different regions provides theory and method supported for regional targets of carbon reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
