【摘要】 在制造业中，通过修理将设备恢复到原有的设定状态，是维护技术系统的任务之一。更新准备报废的或已经报废的机械设备也是其目标。这里，涉及到一个再生利用的方式，其意义多半是被低估了。一台机器经过修理或现代化之后可重新使用，这相对购置新机器而言是一个费用合理和技术上等价的方案，但是人们对此显而易见的优点还未有足够的认识。为了尽可能缩短一个产品的再循环周期，以达到重新取得利用如同一种新产品的效果，这里引用了“再制造”的概念。更多还原

【Abstract】 In manufacturing industry, the original state of machines and equipment will be restored through repair. This is one of the tasks in technical system maintenance. The renovation of the discarded or to be discarded machines and equipment is also one of its targets. Here involved is a form of recycling whose significance is mostly underestimated. After restoring or modernization of a machine, it can be reused. As compared to buying new machines, it is a better alternative of reasonable costs and same technical value. But such obvious advantages have not been fully recognized. In order to shorten the period of recycling of a product with the aim of achieving the same effect as that of a new product, the concept of "re-manufacturing" is introduced here.更多还原
