Analysis on the Evolution Path of Transformation of Manufacturing Enterprises through Servitization——A Case Study Based on ShaanGu Group

Service-oriented manufacturing is an emerging innovative development model,and its core is the deep integration of products and services.It has become a hot issue in current research.In order to deeply explore the evolution path of servitization transformation of manufacturing enterprises,ShaanGu Group is taken as a case,and discusses practical application of service-oriented manufacturing model in different development processes of ShaanGu Group.Thus,four stages of transformation of ShaanGu Group through servitization are summarized:specialized after-sales service stage,rental service stage,engineering complete service stage and financial service stage.Through comparative research,it is found that general evolution path of manufacturing enterprises to service transformation is:the primary stage(providing product-oriented product service system)→the intermediate stage(providing application-oriented product service system)→the advanced stage(providing utility-oriented product service system)→the completed stage(providing pure service).On this basis,some suggestions are provided for manufacturing enterprises to integrate productive services in the process of transformation.

Three-dimensional Analysis of the Evolution Path of Teaching Methods in China--Reflection and Prospect of Information-based Teaching

Under the influence of the information technology revolution,the teaching method,as the way to impart teaching content or the means to realize teaching content,has undergone a process of constant evolution and transformation.This transformation is still ongoing.In order to explain this phenomenon,we establish a three-dimension analysis framework of"ECONOMIC BASE-INFORMATION TECHNOLOGY-CULTURE".All kinds of logics involved in them are closely linked,thus influencing each other.At the same time,these aspects constantly affect the historical trajectory of the evolution.Based on the above analysis framework,the paper uses the historical approach to expound the evolution path on teaching methods in China since ancient times and divides it into four stages.Combined with the practical problems and interview results,we rethink the present information teaching methods.In the end,some suggestions are put forward in order to promote the further development of education-related fields.

Identification, evolution and geological indications of solid bitumen in shales: A case study of the first member of Cretaceous Qingshankou Formation in Songliao Basin, NE China

On the basis of sorting out current understanding of solid bitumen (SB) in shales and taking organic-rich shales in the first member of the Cretaceous Qingshankou Formation in the Songliao Basin as an example, the definition, classification, occurrence and evolution path of SB are systemtically studied, and the indicative significance of SB reflectance (Rob) on maturity and its influence on the development of reservoir space are discussed and summarized. The results show that the difference of primary maceral types is primarily responsible for the different evolution paths of SB. Most of the pre-oil bitumen is in-situ SB with only a small amount being of migrated SB, while most of the post-oil bitumen and pyrobitumen are migrated SB. From the immature to early oil maturity stage, bituminite, vitrinite, and inertinite can be distinguished from SB based on their optical characteristics under reflected light, and alginite can be differentiated from SB by their fluorescence characteristics. Under scanning electron microscope, in-situ SB and migrated SB can be effectively identified. Rob increases linearly with increasing vitrinite reflectance (Ro), as a result of a decrease of aliphatic structure and the enhancement of aromatization of SB. Within the oil window three types of secondary pores may develop in SB, including modified mineral pores, devolatilization cracks and bubble holes. At a high maturity stage spongy pores may develop in pyrobitumen. Scanning electron microscopy combined with in-situ SEM-Raman spectroscopy can further reveal the structral information of different types of SB, thus providing crucial data for understanding for understanding OM migration paths, dynamics, and distances at micro-scale.

The Effect of Spatial Structure Character of Heat Source on the Ray Path and the Evolution of Wave Energy of Meridional Wave Train

This paper studies correlations between the spatial structure character of thermal forcing and deformation and the amplitude of rays of meridional wave train. It is shown that if thermal forcing appears a meridional linear variation the rays of quasi-stationary planetary wave may propagate along oblique lines and if the meridional variability of heat source has second order term the rays show distinct deformation as a great circular route. Additionally, the inhomogeneous distribution may cause lower frequency oscillations in mid- and low-latitudes. The combination of zonal and meridional wave numbers and distributive character of heat source may form an inverse mechanism of variational trend of generized wave energy, reflecting in some degree the physical process of transition between meridional and zonal flow patterns.

Evolution of green development pattern in western China

Since the 18 th Party Congress, green and low carbon industry-oriented industrialization road became a new main industry development direction. Through analyzing four kinds of region industry development modes and current situation of the industrial development of the western region, this paper uses DEA method to evaluate 11 western provinces industry green degree and resource utilization degree between 2008 and 2014, and gets the evolution process of the industrial development pattern during 7 years. The results indicate that: industrial development models are not the same in the western China and green degree are generally low. On this basis, it is concluded that the evolution of green development patterns for reference are 4 kinds of industrial development models. Finally, on the basis of green development pattern evolution path this paper provides advice to improve green degree and the degree of resource utilization.

The Path Evolution for Chinese Modernization of the Rule of Law

The Communist Party of China(CPC)has created a new path for Chinese modernization and a new form of human civilization while leading the people in advancing a great social transformation.Chinese modernization of the rule of law is an integral part of this new path.With a high degree of historical initiative and consciousness,the CPC has solidly grasped the basic regularity of China's legaldevelopmenttbased on actual national conditions,and has successfully pioneered,upheld,and expanded Chinese modernization of the rule of law.Legal construction during the New-Democratic Revolution hasreflected theearly exploration of Chinese modernization of the rule of law.The development of the rule of law during the period of socialist revolution and construction has laid a preliminary foundation for the formation of Chinese modernization of the rule of law.The new great social transformation of reform and opening up has further promoted such modernization.The construction of a law-based China in the new era of socialism with Chinese characteristics marks a further expansion and deepening of modernization.Therefore,Chinese modernization of the rule of law is rooted in the Chinese land,conforms to the characteristics of China,and draws on the excellent achievements of the world's legal civilization.It encapsulates profoundhistorical,theoretical,and practical logic,and has created a new model of modernization of the rule of law in a civilized society.

Hotspots and trends of biological water treatment based on bibliometric review and patents analysis

In order to reveal the hotspots and trends of biological water treatment from the perspectives of scientific and technological innovation, both of the bibliometric review and patents analysis were performed in this study. The Web of Science Core Collection database and Derwent Innovation Index database recorded 30023 SCI papers and 50326 patents, respectively were analyzed via information visualization technology. The results showed that China ranked the first in both papers and patents, while the United States and Japan had advantages in papers and patents, respectively. It was concluded through literature metrology analysis that microbial population characteristics, biodegradation mechanism,toxicity analysis, nitrogen and phosphorus removal and biological treatment of micropolluted wastewater were the research hotspots of SCI papers.
