- 近年来,随着Internet的迅速崛起,互联网已日益成为收集提供信息的最佳渠道并逐步进入传统的流通领域。于是电子商务开始流行起来,越来越多的商家在网上建起在线商店,向消费者展示出一种新颖的购物理念。 网上购物系统作为B2B,B2C(Business to Customer,即企业对消费者),C2C(Customer to Customer,即消费者对消费者)电子商务的前端商务平台,在其商务活动全过程中起着举足轻重的作用。本文主要考虑的是如何建设B2C的网上购物系统。 -In recent

- 1.绪论 1.1冲压的概念、特点及应用 冲压是利用安装在冲压设备(主要是压力机)上的模具对材料施加压力,使其产生分离或塑性变形,从而获得所需零件(俗称冲压或冲压件)的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工,且主要采用板料来加工成所需零件,所以也叫冷冲压或板料冲压。冲压是材料压力加工或塑性加工的主要方法之一,隶属于材料成型工程术。 冲压所使用的模具称为冲压模具,简称冲模。冲模是将材料(金属或非金属)批量加工成所需冲件的专用工具。冲模在冲压中至关重要,没有符合要求的冲
