Research on the present situation and development direction of mechanical engineering intelligence

In the era of Industry 4.0, the traditional mechanical engineering method has been unable to meet the modern manufacturing industry’s demand for efficient, accurate and fast production. Through the introduction of intelligent technology to greatly improve the degree of automation and production effi ciency of mechanical engineering, reduce production costs, improve product quality and accuracy, and further meet the diversifi ed needs of the market, has become an important trend in the development of modern manufacturing industry. Based on this, this paper fi rst analyzes the signifi cance and current situation of mechanical engineering intelligence, and then discusses its development direction combined with relevant practical experience, in order to offer suggestions for the development of modern manufacturing industry

Language Policy and Language Planning: A Comparative Perspective of Economics and Linguistics

Language planning refers to a kind of humanly-conscious intervention within certain limits in the process of language selection. It has not only something to do with the language itself, but is far more involved in such issues as the adjustments of the relations among people or between people and society through language problems. The traditional analysis on language planning is mainly based on sociolinguistic theories, which tends to emphasize the basic concepts and categories in this area so that, at the macro level of public policy, neither practical nor reasonable measures have been able to brought up. The economic rational-choice theory and the cost-benefit analytical method, however, can effectively compensate for the weaknesses of the traditional studies of language planning, and greatly enrich the development of language planning. This paper reviews the connotation and denotation of language policies and language planning in details, discusses the significance and feasibility of conducting economic analysis and research on these two issues, and makes a comparison between the traditional sociolinguistic analysis and the new-rising economic analysis on language planning.language policy; language planning; economics of language
