股骨髁上简单骨折随愈合时期变化的负重能力研究

股骨远端骨折稳定性差、并发症多,目前多主张进行积极的手术治疗。术后的早期康复训练有助于促进骨折愈合,但大多基于临床医生经验,缺乏客观指导。本文通过影像学数据获得了股骨的三维几何模型,建立了使用锁定板固定的股骨髁上简单骨折模型,研究了股骨在单腿站立姿态下,不同愈合时期骨折固定模型的应力分布和传递机制。结果表明:骨折固定模型的应力分布状态受骨折方向和愈合时期的影响,例如锁定板的最大Mises应力在相邻两个愈合期最高相差70%。文章以锁定板系统失效为标准,给出了股骨髁上简单骨折早期承载能力的半定量指标,表明了患者需要针对骨折方向和愈合时期及时调整术后负重大小,对临床康复训练有指导意义

Study on Tobacco- Leaf Inventory Management Strategy Based on Revenues Sharing Mechanism

文中以福建省两烟物流一体化为背景,建立了基于收益共享机制的烟叶代管策略模型,然后采用SHAPlEy值法来确定收益共享比例,并引入了风险修正因子,修正了物流公司与复烤厂之间的收益分配,探讨了物流公司的整合能力、所承担的风险大小、复烤厂烟叶库存成本占总成本之比对收益共享比例的影响。在此基础上,通过数值分析论证了该方法的可行性。分析结果表明,收益共享比例与物流公司库存整合能力系数、承担风险大小、复烤厂烟叶库存成本占总成本之比成正比,采用带修正因子的SHAPlEy值法对于物流公司与复烤厂之间的收益分配更加合理。Based on the background of integrated- logistics of cigarette and tobacco leaf in Fujian province,this paper builds a model revealing revenue sharing mechanism on tobacco- leaf inventory management strategy.Then Shapley value method is adopted to determine the revenue sharing proportion,risk factor is introduced to fix distribution of profit between Tobacco Logistics Company and redrying factory,and this paper's discussion will show revenue sharing ratio is influenced by the coefficient of inventory integration ability,the risk of Logistics Company and inventory cost of tobacco leaf accounts for the ratio of the total cost of redrying factory.On this basis,using the numerical analysis demonstrates the feasibility of this method.The analysis results show that the coefficient,the risk and the ratio is proportional to the revenue- sharing ratio,Shapley value method with risk factors is more reasonable for distribution of profit between tobacco logistics company and redrying factory.中国烟草总公司福建省公司“两烟物流一体化运行模式研究与实践”项目; 国家自然科学基金项目(71371159); 浙江省科技厅软科学研究计划(2014C35018

Effect of ashing temperature on accurate determination of plutonium in soil samples

An acidic leaching method using HNO3 is widely employed to release the global fallout Pu from soil samples for further chemical separations in radioecology and toxicology studies, and in many applications using Pu as a useful tracer. In the method’s sample ash treatment step to decompose organic matter in soil, various ashing temperatures (400 – 900˚C) are used. However, the effect of ashing temperature on the accurate Pu analysis has not been well investigated. In this study, two standard reference soils (IAEA-soil-6 and IAEA-375) were used to determine the ashing temperature effect (from 375 to 600˚C) on HNO3 leaching method. The Pu analytical results of both standard reference materials showed that lower 239+240Pu activity was observed when the ashing temperature exceeded 450˚C, and the 239+240Pu activity continue to decrease as the ashing temperature was raised. Approximately 40% of the Pu content could not be leached out by concentrate HNO3 after ashing for 4 h at 600˚C. The Pu loss was attributed to the formation of refractory materials, which are insoluble in HNO3 solution. This hypothesis was confirmed by the XRD analysis of soil samples which revealed that plagioclase-like silicate materials were formed after high temperature ashing. To ensure the Pu release efficiency in HNO3 leaching, we recommend 450˚C as the ideal ashing temperature. This recommendation is also useful for analysis of other important artificial radionuclides (e.g. 137Cs, 90Sr, 241Am) for which an ashing process is needed to decompose the organic content in soil samples
