1、科技英语标点符号用法（以钢铁专业为例）THE INTRODUCTION TO ENGLISH PUNCTUATION USAGE FOR SCIENCE AND TECHNOLOGY科技英语标点符号用法 （以钢铁专业为例）标点符号是现代英语书面语必不可少的部分，而国内一般英语语法书对标点符号的介绍均较简略；现已出版的英汉科技词典，附录多为化学元素表、度量衡表等，未见将英语标点符号用法作为附录的。有鉴于此，笔者以近年国外英文原版钢铁专业文献为素材，广泛搜集英语标点符号的用法、用例，归纳、整理成文。其中部分内容，鲜见或未见于国内版英语语法书。因此，本英语标点符号用法对于从事科技汉英互译将会有所裨益
