2017年1月份国产圆珠笔尖钢研制成功的消息火速传遍全国，连日推涨太钢不锈的股票，这让太钢人大为惊喜。中国是产笔大国，但圆珠笔的钢材和加工机器都依赖进口。为此，科技部资助国家科技支撑计划重点项目“制笔行业关键材料及制备技术研发与产业化”，核心目标就是圆珠笔头国产化。研发笔尖钢没有任何参考，科研专家不断地积累数据、调整参数、设计工艺方法，有趣的是笔尖钢研制突破的灵感竟然来自家常的“和面”，面要想活得软硬适中，就要加入新“料”，相对应的钢水里就要加入工业“添加剂”。太钢人用笔尖钢精神在“中国制造”的新篇章上写下了光辉一笔。笔尖钢的研发成功说明了（    ）

①事物的主要矛盾决定着事物的发展

②科研数据的不断积累必会实现笔尖钢研制的成功

③意识活动具有主动创造性，笔尖钢精神助我们收获笔尖钢研发成果

④创新来源于生活灵感

法国国王路易十四（1643－1715）任用柯尔柏作为财政总监，先后两次大提关税，几乎排斥了英荷等国毛纺织品的进口，极力招徕外国的能工巧匠来法国定居开业。其做法（）
