求翻译：其次是产业制造能力与技术创新能力严重不对称。例如，我国作为钢铁生产大国，钢产量和成品钢材的产量已是世界第一，出口量也位居世界前列，但这些钢材大都是技术附加值较低的初级产品，高品位的优质钢仅占百分之二十，每年需进口冷轧薄板、冷轧带钢、冷轧硅钢、不锈钢薄板、镀锌板和镀锡板等技术含量高、附加值高的生产用材上千万吨。与国外钢铁行业相比，虽然我们在数量上占有优势，但由于没有掌握深加工的核心工艺技术，缺乏新产品新技术的开发能力，我们在质量、品位、以提高产品技术含量获取高额利润方面，就总是不如人家。是什么意思？

Second, the manufacturing capacity and capability of technical innovation seriously. For example, my country, as iron and steel production, steel production and the finished steel output has is the world's first volume of exports are also among the highest in the world, but the steel is mostly techn

Followed by technical innovation ability of industrial manufacturing capabilities and serious asymmetry. Such as, in China as steel production powers, steel yield and finished steel of yield has is world first, export volume also ranked world forefront, but these steel most is technology added value
