Abstract Non-heritage handicrafts are outstanding achievements and wisdom crystallization jointly created by people of all ethnic groups in long-term life practice, and they are an important expression of the cultural values of the Chinese nation. From the perspective of tourism resources, this paper proposes the coupling path between non-heritage handicraft resources and rural tourism and constructs the planning mode of “non-heritage handicraft tourism”. The evaluation model of the potential of industrialized development of non-heritage handicrafts, which contains 12 factor-level indicators, is constructed by comprehensively applying big data analysis, kernel density analysis, and hierarchical analysis method. The empirical results show that, among the four non-heritage handicrafts, Nixing pottery has the greatest industrialization potential with a high degree of affiliation (0.3621) and a high potential for industrialization and development. The evaluation results have established a scientific and reasonable system for developing or protecting handicrafts for different potential non-heritage craft projects. This can guide the current practice of revitalizing non-heritage crafts in full swing.
In order to create a safe tunnel lighting environment and provide a good driving experience, this paper analyzes the influence of the layout of the luminaires in tunnels on their glare. By establishing a tunnel simulation model, the threshold incremental glare evaluation method is used to explore the relationship between the spacing and height of the luminaire and the glare level for different vehicle types. The research results show that increasing the height of the luminaire can effectively reduce the glare effect, and the glare difference of different models becomes smaller. Increasing the spacing of the luminaires will slightly increase the glare, and the glare difference of different models is almost unchanged. Therefore, the height of the layout and the spacing of the luminaires can be increased to achieve safety and energy saving effects.
The rapidly growing household energy consumption has put huge pressure on coping with global warming and the low-carbon transition of cities in China. Household energy consumption was obstruction to achieve sustainable energy development. This paper establishes a new subdivide model based on the household characteristics, economic level of residents and climate conditions, and its will effectively subdivide household energy use into five end-uses: Cooking/hot water, heating, cooling, lighting, and power. The calculation results reveal that the energy consumption of end-use and its provincial differences in urban areas of China. For the country as a whole, (1) Five end-uses energy consumption has maintained a consistent increase over the past decade, and the share of cooking/hot water has expanded significantly; (2) Heating and Cooking/hot water dominate household end-use energy consumption, accounting for over 70% of the total. From the provincial, (3) End-use energy consumption of urban households varies widely by province, cooling energy consumption is concentrated in southern urban China. (4) Where climatic conditions are an important factor in the difference between heating and cooling energy consumption; The difference in cooking/hot water and power energy consumption results from the number of households. This paper provides a basis for accounting for household end-use energy consumption, which will contribute to a cleaner transformation in energy consumption structure.
Considering the current situation that China's many reefs in the South China Sea have been occupied and a lot of resources have also been plundered,in order to better safeguard our sea rights and lay a good foundation for the construction of China's maritime power,this paper analyzes the concept of effective administration as mentioned by the United Nations Convention on the Law of the Sea(UNCLOS),which is an important criterium of adjudicating the disputed territory.This paper gives the following suggestions;China should identify U-shaped line as the line of islands ownership and make Ocean Basic Law as well as other laws as soon as possible;the administrative body in Nansha Islands should be stronger and more effective;meanwhile,administrative activities should be richer and much more emphasis should be placed on specific activities.
This article presents experimental testing results designed to obtain physical and mechanical properties of glued laminated bamboo (glubam) beams. Two types of glubam beams made with different pre-processed plybamboo boards were tested. One type glubam beam specimens were made with thin layer bamboo strips of about 2 mm thick, and the other were manufactured with thick layer bamboo strips of about 5–6 mm. Test results of the full-scale beams show that the behavior of the glubam beams was elasto-brittle, similar to typical wood-based glulam. The different configurations of bamboo strips have certain influence on the flexural performance of glubam beams, and the mean ultimate capacity of the samples with bamboo strips flatwise is higher than that of edgewise. Based on the experimental results reported herein, the strength capacity equations are proposed for calculating the flexural rigidity and strength capacities of the glubam beams.
In this study,a new dynamic separator was designed by the simulation method with the ANSYS CFX11.0 software. It can be found that the flow field was separated into two parts in the rotor region, i.e. the fluid close to the rotor region went up through the rotor grading face, while the fluid in the distant area revolved around the axle forced by the rotor. The results of particle tracking showed that the particles smaller than 60μm can easily go through the rotor region, but the particles bigger than 100μm can hardly go through it.
The interspecific cross was carried out using modern roses as female parents,while some wild species of Rosa from China,including R. primula,R. xanthina f. spontanea,R. brunonii,R. laxa and so on,as male parents. 20 compatible cross combinations were selected. The stigma receptivity and pollen vitalities of some parents were tested. Combined with precious hybridization studies,the influences of parent's sterility,genetic relationship,ploidy level and environment on inter-specific cross compability were analyzed. The results showed that parents' fertility was not the decisive factor in seed harvest;R. laxa was more compatible than other wild roses when crossed with modern roses. It was probably compatible when one parent of compatible cross was replaced by genetically close species or cultivars. Triploid and tetraploid were generated when hybridization was taken between tetraploid and diploid. Most hybrid seeds of Rosa canina inermis × R. primula and R. canina inermis × R. xanthina f. spontanea were tetraploid. According to the results,a new method of using diploid wild roses was proposed. This study further improved the system of cross-breeding.
From the different angles of the stock indicators,quality indicators,structural indicators and changes in the degree of indicators,the paper proposed the evaluation index system of the construction of regional ecological civilization and discussed the index weight,comprehensive evaluation model and the index synthesis method.Then,the paper discussed the degree of the regional comprehensive ecological civilization,according to the three indicators of degree of development,coordination and duration.The degree of development described the quantitative dimension,the degree of duration described the time dimension and the degree of coordination described the quality dimension.
Glued laminated bamboo (glubam) is a type of engineered bamboo that resembles timber-based glued laminated lumber (glulam). The glubam components are made by laminating 20- to 40-mm-thick engineered bamboo boards; thus, the performance is determined by the quality and properties of the laminated boards. A comprehensive testing program was conducted on typical engineered bamboo boards. The experiments were performed according to the general requirements given by international standards; however, the size of specimens and loading jigs were redesigned according to the modular thickness of typical bamboo boards. Mechanical behaviors and failure modes of the specimens under 15 stress conditions are reported, along with the surface strain distribution recorded through digital image correlation (DIC). A simple design-oriented axial stress–strain model is proposed, and strength values, including the corresponding coefficient of variance (COV), are calculated and provided. A comparison of characteristic strength values between engineered bamboo and typical wood products is also given in this research.
