在传播中

E-mail is one of the most popular communication services around us, but there are some overstaffed problems associated with the MUA of traditional E-mail system. These problems make the E-mail client side cumbrous and difficult to expand on mobile terminals such as cell phone, and PDA etc.

随着人们在网络上的活动日益增加，电子邮件服务在人们的日常生活中越来越重要，大量的敏感信息要在网络上传播，人们对电子邮件服务的便利和安全的要求越来越高，与此同时智能化程度越来越高的移动终端设备如手机、PDA、PocketPC等也逐渐融入人们的生活，人们对移动设备上的邮件服务需求在也慢慢呈现出来，因此如何让邮件用户在各种固定或移动环境下收发邮件具有一定意义。

TV broadcasting is an integral part of these creative industries, inextricably-linked with the mass-entertainment film industry, radio, newspapers, magazines, children's toys, electronic games, fashion - with the advertising industry a very prominent "cement" in that structure…They interlock, incestuously perhaps, and provide constant mutual product and programme support.

电视传播是这些创造性产业中的主要部分，它不可避免地与大众娱乐电影产业、广播、报纸、杂志、儿童玩具、电子游戏、时装等联系在一起，而广告业是这个结构中的一种非常重要的黏合剂……它们互相连锁，也许是混乱错杂地交叉渗透，提供持续合作的共同产品和相互支持的节目。
