【正文】 industrial design—creating a science and healthy way of life. Facing the threat of human survival and sustainable development, in the 20th century, people began to question the sustainable development of humanity ,to carry out a profound reflection on sustainable development and to put forward a suitable model of circular economy , the principle of circular economy is 3R (ie Reduce, Reuse, Recycle) which is of great significance to the implementation and promotion of socioeconomic stability, sustainable development Against this background, the concept of sustainable development into rapid economic development is inextricably linked to the design, based on this ongoing exploration and practice. 3R principles intended to sort out this article on various aspects of industrial design and the guiding role, and attempts to explore the 3R principles of industrial design at the extension. 2 Cycle economic model and the principle of 3R Economy is engaged in production, consumption and reproduction activities, which is to meet human material needs of their own material .Recycling economy is considered following the original economy, the agricultural economy, industrial economy after the time of the postindustrial economy, with the industrial economy is different between the resources and environment the economic cycle refers to the natural ecosystem of the material circulation and energy flow reconstruction of the economic system so that it harmoniously into the natural ecosystems of the material energy recycling process to product clean production, resource recycling and efficient recycling characterized ecoeconomic development patterns, also known as ecoeconomy, green economy. The relationship between economic model, environment and the resources Human survival and economic activities rely on the resources and the one hand ,it is the source of the human beings material system。 Second, to promote. Small is beautiful . Less Is More, the lightweight and pleasant form of products. Third, the design features of the object collation, evaluation, definition, must always focus on the merger, to simplify, optimize, and makes the core functions briefly products。 Second, it will be able to be easy to use or duplicate the functions of independent recovery, enhance the versatility of the ponents, once the endoflife products, they can reuse or recycling。 Second, products are easy to repair and maintenance。 maintain original material, as far as possible the use of simple materials, the use of alloy materials, to avoid material harm to the environment of the surface treatment。 。 In another example, the reengineering of old jeans before, by reengineering can be turned into shorts, vest and so on. 5 Conclusion Circular economy is to achieve sustainable human development of new economic development model, 3R principle is the core substance of the economic cycle, the idea of circular economy is the fundamental expression. Redesign are able to make the best of 3R in the extension of the field of industrial design and development, is a matter of deep study and practice the new task, it should be, together with the 3R principle, bee a model of circular economy are industrial 4R principles of design. As the international chairman of the Federation of Societies of Industrial Design, Mr. Peter said the design of human development as an important factor, with the exception of selfdestruction might be the ruin of mankind, human arrival may also bee a shortcut to a better world. Today, in the framework of national sustainable development strategies, the role of industrial design is changing, and actively looking for a new direction for the development of circular economy at all levels play a role. Industrial design will bee a powerful for cycling of our country economic. 譯文成績 （百分制） ： 指導(dǎo)教師簽名： 年 月 日 備注： 英文原文出處包括出版社、出版時(shí)間、期刊的刊名、刊號、刊期。 the prohibition of the use of contaminated material against big, look for the corresponding sound material substitution。 Second, in the selection and processing of raw materials, the demolition of the connection。 Fifth, the structure of simple, easy to create。 In the consumer area, reduction of the supremacy of the principle of a change in consumer lifestyles and advocate moderate consumption and green consumption. Reuse principle is the second principle of circular economy, that is, process control methods, with the aim to improve the products and resources use efficiency, it calls for product design to initial the form of packaging for multiple items to prevent premature bee waste. In the design, to the use of standardsized parts, repair and upgrade in order to
