今天使用的许多个人和家庭用电子设备以及消费类电子产品,是在过去十年中研制成功的。有些产品现尚在研制之中,可望在1990年前提供使用。一些即使是目前尚不能肯定的产品,亦可望在1990年前从实验室进入市场。消费类电子产品的市场变幻莫测,其成功与失败往往同样惊人。例如,0.5英寸磁带家用盒式录像机,仅仅几年之内就发展成为工业中的领先产品。1984年,家用盒式录像机的销售额占消费类电子产品总销售额的45%。可
Many of the personal and home electronics used today, as well as consumer electronics, have been successfully developed over the past decade.

The market for consumer electronics is unpredictable and its success and failure are often equally alarming. For example, a 0.5-inch tape home video cassette recorder has evolved into a leading product in the industry in just a few years. In 1984, home video cassette recorders accounted for 45% of total sales of consumer electronics products. can
