作为国有中型企业的杭州电声厂，去年瞄准大屏幕彩电发展趋向和高保真音响配套需求，开发了五十多项新产品。

The Hangzhou Electronic Audio Factory, as a medium state-owned enterprise, developed more than fifty new products aimed at the trends in the development of large-screen TVs and the demand for high-fidelity speaker accessories.

数字传输虽然能够把失真度减少到逼近于“零”，但从理论上讲，声音的复制几乎绝对无法做到“全保真”！

精品专卖连锁店，经营国内外名牌商品，主要特色是保真，服务周到。

This boutique chain deals in famous domestic and foreign brands. Its main features are that it provides a guarantee of genuine products and excellent service.

有几年曾有些拍卖公司针对假货太多，买家没有信心等问题，提出过类似的所谓“保真”措施。

A few years ago, some auction companies addressed problems such as a large amount of fake goods and a lack of buyer confidence with a similar measure- a guarantee that products are genuine.
