A major international event for the watch and clock industry-Basel Fair - has recently ended. Among Hong Kongexhibitors the generally feeling was that of slight disappointment. Judging from the respond in the Fair the expectation forHong Kong and China's exports of Watches and clocks to the world market for this year has become rather restrained.2000 was a relatively good year for the timepieces industry of Hong Kong. Its total exports (domestic exports and re-exports together) increased 4…  相似文献

China's State Council recently passed in principle the auto industry rejuvenation plan. Major contents of the plan are:to foster auto consum ption market, including a 50 percent cut in the vehicle purchase tax on passenger vehicles with a displacement of 1.6 liters and below; to promote reorganization of the auto industry and support large auto enterprise groups to carry out mergers and acquisitions, and key auto spare enterprises to expand production; to support independent innovation and technical upgrading by enterprises: the central government wiU appropriate RMB 10 billion in a special fund to support technical innovation and renovation and development of new energy automobiles and spare parts by enterprises in the next three years;to implement a new energy auto strategy :subsidy from the central budget will be appropriated to support the spread of energy saving and new energy automobiles in large-and medium-sized cities; and to promote development of independent brands of automobiles, speed up construction of auto and spare parts exportbases, develop a modern auto service industry and improve auto credit.  相似文献

China's import and export volume reached US $1,338.66 billion in the first eight months of 2009, declining 22.4% year on year. of this, exports accounted for US$730.74 billion, down 22.2%; and the imports accounted for US$607.92 billion, down 22.7%. The trade surplus in the period was US$122.82 billion,dropping 19% from the same period last year.  相似文献

Measure index system of technical innovation in medium and small manufacturing enterprises is established according to principles of exploration, adaptability, standardization, generalization, feasibility, comparability and combination of economic benefit and continual development. It includes index of technical innovation capacity, informational administration on technical innovation, and investment of technical innovation, economic benefit, green technical level, social contribution and other influential indexes. Approach to measure of technical innovation in medium and small manufacturing enterprises is presented based on combination of grey relation and fuzzy hiberarchy analysis, and conclusions are drawn based on practical analysis of 20 medium and small enterprises, which provides the basis for the medium and small enterprises to select technical innovation policies and the government to constitute relative policies.  相似文献

China is launching 880 technical transformation projectssupported by state treasury bonds, in an attempt to improve thetechnical level of key industries, according to the State Eco-nomic and Trade Commission. Starting from the second half of 1999, the Chinese Gov-ernment decided to take out part of state treasury bonds in ad-ditional issue each year to serve as discount interest for loansissued to enterprises carrying out technical transformation andupgrading. A total of RMB19. 5 billion(about US $2. 35 bil-lion) has been earmarked from the additional issue of statetreasury bonds in 1999 and 2000 to support the 880 pro-  相似文献

Crimping is used in production of large diameter submerged-arc welding pipes. Many researches are focused on crimping in certain manufacturing mode of welding pipe. The application scopes of research achievements become limited due to lack of uniformity in theoretical analysis. In order to propose a crimping prediction method in order to control forming quality, the theory model of crimping based on elastic-plastic mechanics is established. The main technical parameters are determined by theoretical analysis, including length of crimping, base radius of punch, terminal angle of punch, base radius of die, terminal angle of die and horizontal distance between punch and die. In addition, a method used to evaluate the forming quality is presented, which investigates the bending angle after springback, forming force, straight edge length and equivalent radius of curvature. In order to investigate the effects of technical parameters on forming quality, a two-dimensional finite element model is established by finite element software ABAQUS. The finite element model is verified in that its shapes error is less than 5% by comparable experiments, which shows that their geometric precision meets demand. The crimping characteristics is obtained, such as the distribution of stress and strain and the changes of forming force, and the relation curves of technical parameters on forming quality are given by simulation analysis. The sensitivity analysis indicates that the effects of length of crimping, technical parameters of punch on forming quality are significant. In particular, the data from simulation analysis are regressed by response surface method (RSM) to establish prediction model. The feasible technical parameters are obtained from the prediction model. This method presented provides a new thought used to design technical parameters of crimping forming and makes a basis for improving crimping forming quality.  相似文献

1 China's Economy Continues to Maintain Stable Growth. 2001 is the first year for the implementation of the TenthFive-Year Plan (2001-2005) for national economic andsocial development. From now on, China's economy continuesto maintain sustained rapid and sound development. The inier-nal and foreign investment continues to grow stably. Thanks to continuously implementation of expanding do-mestic demand course, proactive fiscal policies and prudentmonetary policies by Chinese government, China's economyexperienced sustained, rapid and sound development in the firsthalf of this year, and the scale of the fixed assets investmentcontinues to expand. In the first five months, the fixed assetsinvestment amounted to RMB619. 9 billion yuan or USD74. 96  相似文献
