The transformation of the structure of the market economy has prompted enterprises to seek for new developments and innovations. Under the background of the new economy, enterprises must begin from the perspective of internal management and internal strategic development to ensure quality enterprise operation mechanism innovation. This would help direct enterprise operation and development as well as demonstrate the value of enterprise internal management. In this way, enterprises will be able to array their overall competitiveness. This paper comprises a detailed analysis of the connotation and innovation of enterprise operation mechanism under the economic transformation, with the purpose of investigating the innovation strategy of enterprise operation mechanism under the economic transformation.展开更多

Yunnan has highly focused on the task of the treatment of residential domestic sewage and household garbage in rural area. Many efforts and resources have been put into this field in Yunnan since 2016. Progress has been made to increase the coverage rate of the sewage and household garbage treatment facilities. Seventy-five percent of total administrative villages have built up garbage transportation system and treatment facilities. Sixty-three percent of towns have collected and treated the residential domestic sewage by constructing various scale sewage treatment stations. However, the lack of the long-acting operation mechanism and the imperfection of the charge rules for the sewage and garbage treatment facilities have become problems that would hinder the achieving of the environmental goals in Yunnan. The reasons were elaborated on the basis of the local actual situations. Therefore, it is significant to improve the charge rules and frame the long-acting operation mechanism by strengthening the governance capacity, frame an overall mechanism and encourage the mass to be involved in the improvements of the living environment in rural Yunnan.展开更多

The mechanisms of the extension are analyzed in this paper. Lithiumization diminishes the impurities and hydrogen recycling to the lowest level. After lithiumization a high density up to 7×1019 m-3 was obtained easily by strong gas puffing with ordinary ohmic discharge alone. More attractively we found that metal Li-coating exhibited the effects of wall stabilization. The low qα limit with higher density was extended by a factor of 1.5-2 in comparison with that for boronization, and 1.2 for siliconization. Siliconization not only extended stable operating region significantly by itself, but also provided a good target plasma for other experiments of raising density limit. Core fuelling schemes are favourable especially for siliconized wall with a higher level of medium-Z impurity (Z = 14). After siliconization the maximum density near to 1020 m-3 was achieved by a combination of supersonic molecule beam injection and multipellet injection. The new defined slope of Hugill limit illustrating more clearly the situation under low qα and high ne discharges was created to indicate the new region extended by combining IP ramp-up with core fuelling. The slope with a large Murakami coefficient increased by a factor of 50-60 %.展开更多

Chinatex’s import and export value totalled US$2.718 billion last year, a rise of 43.9% over the previous year. The quality of the exports also improved. The company’s Beijing branch exported US$370 million worth of goods, 33.3% more than in the previous year. Its enterprises abroad had a turnover of US$1 billion in 1994.展开更多

The ultimate goal of the rule of law lies in identifying and protecting the rights of citizens. Way to protect the rights of citizens is diverse, but the judicial relief is the most basic and important form of insurance. Everyone can “into” the court and get the impartiality of the judicial relief, is a measure of a country judicial level height and the rule of law implementation degree of important yardstick. Judicial system and judicial procedure to build and build a better, if the subject of litigation rights are not being met and the safeguard, can’t get through the door and it is the legislators and legal scholars over the many efforts are meaningless, under this basic condition, we propose the new perspective on the corresponding issues that is necessary.展开更多
