Based on the research, founded on existing production conditions, production capability and technical natures of KISC, especially its own development requirements, linked with the development trend of the iron and steel industry, fully considering the continuity of equipment upgrade and technical optimization of KISC, guided under principles of validity and benefit, the writer analyses and argues that in current conditions. KISC shall not adopt the hot metal pretreatment of desiliconization, dephosphorization and desulphurization, but the end-point converter process to improve the dephosphorization effect. But according to the development plan of KISC, with its scale development, upgradeof equipment and technical conditions and implementation of a plan to use high-phosphorus ironstone, its more suitable to adopt the converter-shaped pretreatment of desiliconization, dephosphorization and desulphurization.

在此研究基础上，立足昆钢当前生产条件、生产能力和工艺特点，特别是昆钢自身发展需要，结合钢铁工业发展趋势，充分考虑昆钢现行装备改造和工艺优化的延续性，以有效性和经济性原则为指导，分析讨论了在昆钢当前条件下，不适宜采用铁水"三脱"预处理工艺，而宜考虑采用转炉复吹技术以达到改善转炉吹炼过程脱磷效果的目的；而根据昆钢的发展规划，随着昆钢的规模化发展，生产装备及工艺条件的更新改善及利用高磷铁矿计划的实施，则适宜采用转炉型"三脱"预处理技术。

With reference to the experience of specific practice on strategic alliance in typical domestic and overseas port like New Jersey Port in New York, port of Kaohsiung, Keelung and Taizhong, major ports in Yangtze River Delta, the possible modes of Rizhao Port strategic alliance were proposed. Based on the previous analysis, specific design on the supply chain management system of Rizhao Port viewing from strategic alliance was given in this dissertation, which mainly covered two aspects. On the one hand, based on the overall review of common design process, structure design and selection of partnership of supply chain management, and with consideration of the development trend of Rizhao Port, the double-sector style supply chain structure mode of Rizhao Port was put forward based on strategic alliance. On the other hand, in order to make it more clear on the specific process and contents of this kind of supply chain structure, the specific implementation of five supply chain for Rizhao Port in which capital was taken as the hub were proposed, named as, the coal supply chain based on norm regular ship transport mode, the ironstone supply chain based on cost optimization, the crude oil transport supply chain with the aim of extending petrifaction industrial chain, the timber transport supply chain based on circulating economy concept, and the farming transport supply chain based on futures theory.

在前文分析的基础上，论文重点论述了基于战略战略联盟的日照港口供应链管理的总体框架构建和具体规划设计两方面：一方面，在对供应链管理一般构建流程、结构设计、供需均衡及合作伙伴选择等方面进行全面总结基础上，并结合日照港口的发展趋势，推出了基于纵向战略联盟的日照港口集团式双扇形供应链结构模型；另一方面，为进一步理清日照港口双扇形供应链结构中相关供应链的具体流程及内容，特提出了以资本为纽带日照港口五大供应链的具体设计，即基于准班轮运输模式的日照港煤炭供应链，基于成本最优化日照港口铁矿石供应链，以延伸石化产业链为目标的日照港原油运输供应链，基于循环经济理念的日照港木材运输供应链，基于期货理论的农业定单式日照港农业运输供应链。

In late Tang period,influenced by west Asian great cutting Dao,each 'country' is more powerful because of this shape.Because it's hard to find iron and ironstone,a lot of sword was needed to re-smelted.Moreover the former shape didn't reach the new war condition,so it's abandoned and there's little exsited(only inscribed in Tang poems and Tang drawings).

二、在唐末五代十国时期，受中西亚大砍刀的影响，各"国"因为此刀型比原有唐刀更加结实有力，先后装备这种刀型，加上当时各"国"贸易流通受政治影响极大，铁和铁矿石很难买到，故须将大量的刀剑重新回炉炼制此新刀型，加上原有刀型无法适应新的战争条件，导致此刀型被废弃，故现存实物极少（只在唐诗、唐画中有描绘）。
