前言 表壳材料是手表工业中用量最大的金属材料。由于表壳的防护作用以及直观的影响,在手表工业中享有很重要的地位。尤其是在国际市场剧烈竞争的今天,表壳的色泽和外观造型,往往在很大程度上影响着手表的身价。为此,手表制造商们在表壳材料的研制方面作了不少工作,以期获得竞争能力。为了对国外表壳材料的发展状况有一个概貌的了解,以利于国内表壳的生产和发展,我们进行了国外表壳材料专利文献的调研工作,查阅了二十年代末至八十年代初约六十年的化学文摘,共收集专利361篇。
Foreword Case material is the largest amount of metal used in the watch industry. Due to the protection of the case and the intuitive impact, the watch industry enjoys a very important position. Especially in the fierce competition in the international market today, the color and appearance of the case shape, often to a large extent affect the worth of the watch. To this end, watch manufacturers in the development of case material has done a lot of work, in order to obtain competitiveness. In order to have an overview of the development of the foreign case material in order to facilitate the production and development of the domestic case, we carried out research work on foreign case material patent documents, and consulted about the late 1920s to the early 1980s Sixty years of chemical abstracts, a total of 361 patents collected.
