国Ⅲ实施
几遭波折,几度延迟,2011年7月11日,国Ⅲ标准终于施行,行业震荡随即而起。就宏观层面看,国Ⅲ是行业洗牌的加速器;就微观层面看,国Ⅲ是道"坎",在技术、成本、市场方面对企业提出了更高的要求。无疑,这把"双刃剑"可将强企武装得更强,也可将弱企斩于刀下。而投机取巧的"假国Ⅲ"们,仅能在这场刀光剑影的夹缝中偷生一时,惹得市场短暂混乱,而明与暗,白与黑,定将在国Ⅲ潮流中趋于清晰。国Ⅲ,为中国摩托车行业实现产业升级奠定了基石。 相似文献

Nb3Sn and other A15 members have been widely applied in nuclear power, nuclear magnetic resonance, and high-energy particle accelerators for their high critical current density (Jc) and upper critical field (Bc2). There have been comprehensive and intensive studies on the applications, the fundamental lattice dynamic and electronic properties, etc., of A15 superconductors. Various reviews on the preparations, structures, and properties have already been written in the last few years. Nevertheless, on account of the large amount of existing facts and views, a coherent view on the relations between the structures and properties has not appeared to unify the facts. This article sketches a multi-scale point of view on the relations between the multi- scale structures and the corresponding properties. 相似文献
