On 1 April 2017 China established Xiongan New Area in Hebei Province, which was described as ‘a strategy crucial for a millennium to come'. A point of interest for the public is to be aware of the historical climate change in this new area; however, results from previous global-scale or largerregional-scale averages provide relatively limited information because of the distinct regional differences in climate change. This study analyzes the changes in mean and extreme temperature in this area, based on homogenized daily temperature data for the period 1960–2016. The results show a significant warming in the indices of annual, summer, and winter mean temperature(Tmean), maximum temperature(Tmax), and minimum temperature(Tmin). The linear rate of annual Tmean is 0.34 °C/decade. Temperatures on the hottest day, the warmest night, the coldest day, and the coldest night, every year, all show increasing trends, with the trends in the two nighttime-related indices being significant. An increasing occurrence of warm days, warm nights, hot days, and tropical nights, but a decreasing occurrence of cold days, cold nights, icing days, and frost days, are found, all of which are significant, except for the occurrences of hot days and icing days. A significant extension of the length of the thermal growing season is also found. The magnitudes of change in most of the temperature indices in Xiongan New Area are larger than those of the adjacent Jing-Jin-Ji and North China regional mean. These results could provide valuable information for policymakers, city planners, engineers, and migrants to this new area. 展开更多

It contains physical and sensory properties. In recent years, the material design in indoor environment tends to be more rational, it not only pursues the external performance of material, but also pays more attention to the health and emotional of residents on the basis of scientific and rational use of its properties. This paper based on some scientific methods of literature study, field survey and case study combs the new trends of material design and analyses specific performance and application of materials in development. It is expected that the research can enrich the theory of contemporary material design and provide valuable reference for future material and interior environment design. 展开更多

[Objectives]This study was conducted to deeply understand the effects of production process on the quality of new types of tobacco sheets with different flavors.[Methods]Based on the pilot production process of thick pulp method,four different flavors of tobacco sheets were sampled at several links in the production process,for the detection of the contents of the main components in the samples,including propylene glycol,glycerol,menthol and glyceryl triacetate,so as to explore the change trends of various components in the thick pulp process.[Results]The change laws of propylene glycol and glycerol contents had a very high similarity,showing a trend of first decreasing and increasing then.The changes of menthol content and glyceryl triacetate content were greatly affected by the specific flavor formula.As one of the indexes of the new tobacco evaluation system,the alcohol-to-ester ratio data need to be further improved in the actual production and application process.[Conclusions]This study provides basic data support for improving the quality of tobacco sheets. 展开更多

With never-ending changes and improvements and an increasing industrial scale of the Internet, the emerging new application trends, such as social networking, network video, intelligent search and mobile Internet, and new Internet technologies, such as Mashup, artificial intelligence, grid computing and open platform, are significantly influencing the Internet industrial structure. Moreover, the rapid development of the Internet and the convergence of the Internet and telecom networks, especially the development of mobile Internet, are giving the telecom industry a shock. This shock will certainly change the structure of the telecom industry, gradually break the monopoly status of telecom operators, shift the telecom emphasis to services and contents, and enhance the importance of terminal vendors in the industrial chain. 展开更多

We elaborate support system of edible fungus industry from outlook on ecological economic development, legislation and standardization of variety approval, multiple-function innovation platform of industrial development research, and perfect talent cultivation and education system. Besides, we analyze the development trend of edible fungus industry from competitive advantages, position and role in national food security, industrial development trend driven by internal demand, diversified industrial development model, division of labor within the industry, and expansion of industrial chain. Then, from the point of zoning and planning of edible fungus industry, we put forward suggestions that it should start from modern industrial system and take the industrial cluster development and optimization as guidance. In addition, we present technical innovation direction of industrial development. It is proposed to strengthen propaganda, build industrial cultural atmosphere, and expand social cognition degree of edible fungus industry to promote its redevelopment. Finally, it is expected to promote international influence of edible fungus industry through experts appealing for policy support. 展开更多
