由于非限制性定语从句与主句的关系比较松散，且中间由逗号分开，意义上与主句是相对独立的，因此，非限制性定语从句的译法主要是分译法。

 (1)译成并列分句

例 1 They are preparing to cover their requirements in a third country, where the prices are more competilive than those offered by you. 

译文:他们打算到第三国购进所需，那里的价格比你们的更优惠。

例 2 We have offered to purchase various equipments for your factory, which will increase its products，improve quality and raise its efficiency.

译文:我方愿意为贵方工厂购买各种设备，以扩大生产，改进质量，提髙效率。

例 3 The seller shall get the signed B/L from forwarding agent，a copy of which will be sent to the buyer by airmail.

译文:卖方应向装运代理领取签署的提单，并将其中一份通过航空寄给买方。

例 4 Another is called“ Preference Stock ”，which is adopted by part of corporations.

译文:另一种叫“优先股”，为部分公司所采用。

 (2)译成独立句

例 5 Large economic spaces involving key trading partners have emerged, which could contribute to trade liberalization as well as to the multilateral trading system.

译文：由主要贸易伙伴参加的大型经济区现已形成。这将有助于贸易自由化和多边贸易体系。

例 6 This visit is a symbol of the good faith, with which we seek to build upon the strength of our friendship, our cultural and commercial ties, and our important strategic relationship.

译文:这一访问是一种诚意的象征。我们正是怀着这种诚意，力求加强我们之间的友谊，加强文化、贸易以及重要战略关系。

 (3)译成相应的汉语偏正复句 

英语中有些非限制性定语从句兼有状语从句的职能，在逻辑上与主句有状语关系，说明原因、结果、目的、让步、假设等关系，翻译时应善于从英语原文的字里行间发现这些逻辑上的关系，然后翻译成汉语中相应的偏正复合句。
