万事万物由“阴阳相济”而生,这是一条普遍的哲理。它不仅对客观世界中的事物适用,对人工世界也同样适用,它是放之四海而皆准的。人工世界的许多产物正是两项技术集成的结果,或者说,是两项技术联姻的结晶。信息技术尤其如此,所以信息技术产品都形成了家族系列,这是人们已经司空见惯的了,这样的实例比比皆是,不胜枚举。例如:由于收音技术和录音技术的集 Everything from the “yin and yang,” born, this is a common philosophy. It applies not only to things in the objective world, but also to the artificial world, which are universally applicable. Many products of the artificial world are the result of the integration of the two technologies or, in other words, the result of a marriage of two technologies.

For example: due to radio technology and recording technology set
