2. 否定词的转换

汉语中有否定意义的词语译成英语时可转换为肯定表达，这样不但可以保持原文的确切含义的着重点，而且可使译文简洁顺畅。

例6. 如果仲裁员不采取行动或他在法律上或事实上无法执行其职务，则应适用以上各条所规定的关于异议和更換仲裁员的程序。

上句子中的否定表达英译时最好转换为肯定表达。

译文：In the event that an arbitrator fails to act or in the event of the dejure or in fact impossibility of performing his functions , the procedure in respect of the challenge and replacement of arbitrator as provided in the preceding articles shall apply.

译文中用fails to act表达不采取行动，impossibility of performing…表达无法执行，精练简洁，不失原意。

3. 扩充

扩充是指在合同翻译中补充ー些必不可少的词语，以便使译文更加确切地表达原意。

例7. 合同的有效期内和有效期满后5年以内，甲方应对乙方提供的专用技术和任何资料保密。

译文：During the validity period of the Contract and for 5 (five) Years after the validity period, Party A shall keep the know-how and any of the information supplied by Party B secret and confidential.

把保密译成keep…secret and confidential,意思更完整。 

例8. 合同期满后，甲方仍有权使用乙方提供的专用技术，即甲方仍有权设计、制造并使用和销售合同产品。甲方向国外出口合同产品只有事先与乙方议妥后，才能迸行。

译文：After the expiration or termination of the contract, Party A shall still have the right to use the know-how supplied by Party B，i.e, Party A shall still have the right to design manufacture, use and sell the Contract Products in the People's Republic of China only. Party B agrees to discuss after the expiration of the Contract with Party A the possibilities of export by Party A to a third country.
