In order to reduce the developing costs , increase the product developing speed ; enterprises must reuse the available resources farthest . but satisfying the personality demands means that we ca n ' t reuse the available resources completely 为了降低产品成本并提高开发速度，企业应最大程度地重用现有资源，但满足客户个性化需求，意味着不能充分地利用企业的现有资源。
Article 11 . for the foreign invested enterprises that increase 10 % or more tech developing cost that the last year , therefore 50 % actual value of the said total cost will offset the cit in current year after the approval of the tax administration 十一、外商投资企业技术开发费比上年增长10 %及以上的，经税务机关批准，允许按技术开发费实际发生额的50 %抵扣当年度的应纳税所得额。
Would you like to have your web site reach to hundreds of millions of chinese viewers only at a fraction of your web developing cost ? it is projected that there will more than fifty million internet users in china by the year 2005 您花费了时间，精力和不小的费用设计制作了您的网站，那么您是否希望再花费您已用去费用的一点点零头，使成千万的外国互联网使用者可以访问您的网站？
Those testing systems can be used only once . thus results in disadvantages such as lower reuse of software , longer developing period , greater developing workload and higher developing cost . and there are more errors left in those systems 这样的考试系统只能一次性使用，系统的使用率低，这就造成了软件复用量小，开发周期长，开发工作量大，开发费用高等缺点，而且系统中遗留的错误比较多。
This paper sets up a solid model with multiple real piston skirt form . it sums up a evaluating way to piston form by testing result . for the piston developing cost and time is largely lowered , it has obvious efficiency both in economy and society 本文采用实体建模，建立了多种真实活塞形状与形线，结合现有的实验和实际使用结果，归纳出了活塞形线的评定方法，大大降低了活塞的开发费用，缩短了定型周期，具有一定的经济效益和社会效益。
The exporting companies should coordinate with the agricultural departments to teach the farmers how to plant vegetables scientifically ; and the manufactures of pesticides and fertilizers should coordinate with vegetables processing companies to develop cost - effective and poison - less fertilizers and pesticides 出口企业应与农业部门联合开展科学种菜指导，化肥、农药生产企业应与蔬菜生产加工企业合作研发适合不同蔬菜的环境友好和高效低毒产品。
The c / s mode system has the disadvantages of high developing cost , complex software maintenance and difficult system migration , which make the fully utilizing of the manage system in the whole enterprise impossible , to say nothing of the usage in a broader scope 单一的c s模式系统开发成本较高、软件维护复杂、系统移植困难，使管理系统在整个企业甚至更广泛范围内得不到充分利用；采用b s模式，简化了客户软件开发，然而对数据安全性提出了更高要求，同时较难实现复杂数据交互窗口功能。
Because of china economy of these a few years is growing all the time , per capita , consumption level , and purchasing power is increasing , still have a bit very crucial , the value of land also is increasing at full speed , estate develops cost to also can increase accordingly undoubtedly , it is difficult also that so house price wants to drop 因为中国这几年的经济一直在发展，人均收入，消费水平，以及购买力都在增加，还有很要害的一点，土地的价格也在飞速增加，房地产开发成本无疑也会相应增加，所以房价想跌也难。
In order to reducing the amount of the experiments , shortening new engine develop period , decreasing the developing cost and improving the product competitive ability accordingly , we can analyze and compare the different engine developing schemes by the means of integrating simulation and experiment together 充分掌握和分析发动机瞬变过程是对发动机瞬变特性进行改善的基础,了解发动机瞬变过程存在的问题,才能有针对性的解决问题,所以,有必要对发动机瞬变过程进行系统的研究。
Modeling of mechanics multibody system is the primary sustaning technology of virtual prototype . it is the base of virtual prototype to realize simulation . design and control . the technology of virtual prototype has changed the tradisional design based on physical prototype , and has greatly reduced the expensive and time wasting manufactrue and exprements of physical proto type . it allows the users analyse and compare rared of designe plans fastly . it can realize optimized design , and can find the potential questions in the early design . it is the effective method to improve qualities of products , to shorten the developing cycle , and to reduce the developing cost 机械多体系统动力学建模是虚拟样机的主要支持技术之一，它是虚拟样机实现仿真、设计制造和控制运行的基础。虚拟样机技术改变了传统以物理样机为基础的设计，大大减少了昂贵而费时的物理样机制造及试验过程，使用户可以直接在计算机上快速分析比较多种设计方案，进行优化设计，在设计的早期及时发现潜在的问题，是提高产品质量、缩短产品开发周期，降低产品开发成本的有效途径。
