“…An online ticketing system covering all stations in China has been initially established after the iterative development of the first five versions. The system is mainly deployed by the Ministry of Railways and railway administrations in local stations (Liu, 2001;Wang & Liu, 2001), and provides services for passengers via offline channels such as station ticket office, TVMs and ticket agents.…”

PurposeWith the yearly increase of mileage and passenger volume in China's high-speed railway, the problems of traditional paper railway tickets have become increasingly prominent, including complexity of business handling process, low efficiency of ticket inspection and high cost of usage and management. This paper aims to make extensive references to successful experiences of electronic ticket applications both domestically and internationally. The research on key technologies and system implementation of railway electronic ticket with Chinese characteristics has been carried out.Design/methodology/approachResearch in key technologies is conducted including synchronization technique in distributed heterogeneous database system, the grid-oriented passenger service record (PSR) data storage model, efficient access to massive PSR data under high concurrency condition, the linkage between face recognition service platforms and various terminals in large scenarios, and two-factor authentication of the e-ticket identification code based on the key and the user identity information. Focusing on the key technologies and architecture the of existing ticketing system, multiple service resources are expanded and developed such as electronic ticket clusters, PSR clusters, face recognition clusters and electronic ticket identification code clusters.FindingsThe proportion of paper ticket printed has dropped to 20%, saving more than 2 billion tickets annually since the launch of the application of E-ticketing nationwide. The average time for passengers to pass through the automatic ticket gates has decreased from 3 seconds to 1.3 seconds, significantly improving the efficiency of passenger transport organization. Meanwhile, problems of paper ticket counterfeiting, reselling and loss have been generally eliminated.Originality/valueE-ticketing has laid a technical foundation for the further development of railway passenger transport services in the direction of digitalization and intelligence.

“…Industrialization of olives in the main three provinces in 2015 [18]. In 1985, the first olive enterprise in China was established in Santai county of Mianyang city, Sichuan province [19]. By the end of 2015, there were more than 40 olive enterprises in China, and more than 20 virgin olive oil production lines were established.…”

China, as a non-Mediterranean country with non-Mediterranean climate, is taking olive cultivation as an important part of its agricultural development. In order to highlight some important facts about the history, status, distribution, and trends of the olive industry in China, we performed analyses based on Internet databases, online GIS software, and scientific papers. Results show that the olive industries have been concentrated in several key areas in Gansu, Sichuan, Yunnan, Chongqing, and Hubei. However, the business scope of olive enterprises is still narrow, the scale of enterprises is generally small, and individual or family management of farmers plays an important role. Thus, increased investment and policies are needed to enhance their capacities of R&D and production, and Chinese investigators should carry out socioeconomic studies at the microcosmic level and take the initiative to innovate the products by cooperating with people in the same professions worldwide.

In response to the problems of low straw utilization efficiency and poor returning effect in Northeast China, this paper takes rice straw containing cow dung as the experimental material, and according to the characteristics of lignin glass transformation of the material, proposes a new method to prepare biomass seedling trays. The seedling trays prepared by this method can meet the needs of corn seedling cultivation and transplantation. To study the molding mechanism, scanning electron microscopy and a universal testing machine were used to compare the changes in the internal structure and mechanical properties of the regularly- and hot-compressed seedling trays before and after seedling raising. The results show that the material with water content of 23% has the best hot-pressing effect. The forming mechanism is: that the strength of the molded seedling tray resulted from the mechanical setting force of the multilayered stem fibers with a mosaic structure within the seedling tray. The adhesion and wrapping by lignin prevented water penetration from damaging the multilayered stem fibers and slightly improved their strength. The seedling tray made of straw and manure was completely degraded over 40 days, and the straw degradation rate was improved. This method can increase the overall quality and benefits of straw, providing a foundational reference for high-quality and high-efficiency straw utilization.
