专利翻译中,专利说明书正文翻译通常分为三大部分:引言、发明描述和具体实施方案。引言(Introduction)陈述该发明的目的、所属技术领域、目前的技术状况和存在的问题;发明描述(Description of the  Invention)陈述该发明的技术详情、方法和效果,使同行中等水平的技术人员可以做出来;具体实施方案(Embodiment)举例说明该发明的最佳实施方案,要有2-3个实例,这是说明书中陈述技术细节最详尽具体的部分,因而是技术情报检索者阅读之重点所在。

专利说明书翻译的内容是保护科技发明权的法律文件,不同于学术论文翻译,故其翻译内容对发明的细节充分公开,以求法律的保护。而对发明的理论问题,则简而略之,甚或只字不提。对学术研究者,常感美中不足。下面是一件专利说明书正文的英译中翻译对照。

PROCESS FOR RECOVERING PRECIOUS

This invention relates to a proces of recovering metals from dilute aqueous solutions of metal salts by contacting a dilute aqueous solution containing dissolved metals with a fibrous proteinaceous material of animal origin.  In one of its more specific aspects, this invention relates to a process for recovering precious metals and base metals from an aqu-cons liquid containing one or more of such metals in solu-tion by contacting said aqueous liquid with a proteinaceous substance selected from the group consisting of feathers, hair,hoof meal and horn meal.

Industrial' waste waters often contain various’metals which for ecological or economical reasons it would be desirableto recover or remove from the water.  It is known, for example, that large quantities of gold and other valuable metals are contained in sea water, but, up until the present time at least, there has been no economic method for recovering it.
Many industrial waste waters contain dissolved salts of such economicaly important metals as platinum, rhodium, pala-dium, ruthenium, iridium, gold, and silver, as wel as basemetals, such as zinc, aluminum, iron, copper, tin, and nickel.
Such dissolved metals are present as anions as wel as in the form of anionic complexes and are contained in wastes, suchas spent plating liquors and refinery waste solutions.

贵重金属回收法

本发明是一种自金属盐类的稀溶液中回收金属的方法。这种方法是将动物性的纤维状蛋白质材料与含有溶解了的金属的稀水溶液相接触。本发明的特点是;本法可自含有一种或数种金属的水溶液中回收贵金属和贱金属,只需将上述水溶液与蛋白质物质相接触即可。蛋白质物质选自羽毛、毛发、蹄粉和角粉。

工业废水常含各种金属。为了维护生态和经济核算,自废水中回收和除去全属是很必要的。举例来说,如所周知,海水中含有大量的金和其他贵重金属,但时至今日尚无一种经济的方法予以回收。许多工业废水中含有经济价值很高的金属盐类,如铂、铭、把、钉、铱、金和银,以及贱金属,如锌、铝、铁铜、锡和镍。这些已溶解的金属以阴离子和阴离子络合物的形式存在于废液中,如废电镀液及精炼厂废液中。
