In the highly competitive market , traditional manufacturing industry faces the challenge of reducing product development time , improving quality , reducing cost and lead - time for production 在激烈竞争的市场环境中，传统制造业面临着加速产品更新换代，提高产品质量，降低生产成本以及缩短生产周期的严峻挑战。
Through this study , it was basically solved the theory and technology problems of modification oil heater to nature gas heater and it will provide with the important referenced value for updating products of manufactory 通过本课题研究，基本解决了现有燃油加热器改型燃气加热器的理论和技术问题，对生产企业的产品更新换代具有重要的参考价值。
With the increasing for the function requirement of mechanical product , the period that the product is regenerated becomes more and more short , but the traditional product design and analysis method ca n ' t suit the requirement needed by modern society 随着对机械产品功能要求的日益增多，产品更新换代的周期缩短，传统的设计分析方法已经不能适应现代社会的要求。
The control of pfc is digital control , it brings the advantages of sample circuit 、 immunity to noise 、 high reliability and debug expediently . so it is easy to update system with immovable circuit to satisfy the need of variational clients 该pfc控制是在软件中实现的,可以在完全不改动电路的情况下,对系统进行升级,满足不断变化的用户的需要,大大减少了产品更新换代的成本。
It brings the advantage of programmability , immunity to noise , and eliminates redundant voltage and current sensors for each controller . programmability means that it is easy to update system with enhanced algorithms for improved reliability 控制是在软件中实现的，可以在完全不改动电路的情况下，对系统进行升级，满足不断变化的用户的需要，大大减少了产品更新换代的成本。
The implementation regulations specifically provide that fixed assets qualified for accelerated depreciation allowance include : ( 1 ) fixed assets fast becoming obsolete ; and ( 2 ) fixed assets in a state of vibration and being exposed to high degree of erosion 实施条例据此明确，可以享受这一优惠的固定资产包括： （一）由于技术进步，产品更新换代较快的固定资产； （二）常年处于强震动、高腐蚀状态的固定资产。
The 21st century is full of challenger and opportunity . facing drastic competition , production rapidity renewal , and the customer demanding continual variety , which made manufacture develop in much - species , small - batch and custom production mode 21世纪是充满挑战与机遇的世纪，面对激烈的国际竞争环境，产品更新换代不断加快，人们对产品多样化需求逐渐增加，使得制造业向多品种、小批量、定制型生产方式发展。
Conclusion product development is an important approach for the company to win advantage in the pierce competition happened in the market place . it can not meet the market need of day - to - day accelerating change products to regard product development only as research technician ' s job 结论产品创新是企业在激烈的市场竞争中获得优势的重要手段，把产品创新当作开发人员的工作的职能管理，己不能适应产品更新换代日益加快的市场需要。
Since the electronic products renew very often and competition of industry become increasingly vigorous , the electronic element firms as the assembly plants " suppliers are comfronted by the pressure of persistant cost reduction , while the life cycle of electronic element also get shortened 随着电子技术的日新月异、电子产品更新换代迅速、行业竞争日趋激烈，给为之配套的上游电子元器件企业带来了产品生命周期缩短、持续降低成本的压力加大的影响。
Stamping - die , which belongs to short period and much variety products , is the important machining equipment for modern industrial products . the speedup of industrial products update has put forward high request to the designing quality and efficiency of stamping die , so it is inevitable trend to adopt cad technology in designing stamping die according to its different characteristic in different application fields 冲裁模是现代工业产品成形的重要设备，属于小批量、多品种产品。随着产品更新换代的速度加快，对冲裁模的设计质量和效率提出了更高的要求。因此，针对各领域的冲裁模应用的不同特点，采用cad技术进行冲裁模的辅助设计是必然的趋势。
