Antarctic sea ice is an important part of the Earth’s atmospheric system,and satellite remote sensing is an important technology for observing Antarctic sea *** Chinese Haiyang-2B(HY-2B)satellite altimeter data could be used to estimate sea ice freeboard and provide alternative Antarctic sea ice thickness information with a high precision and long time series,as other radar altimetry satellites can,needs further *** paper proposed an algorithm to discriminate leads and then retrieve sea ice freeboard and thickness from HY-2B radar altimeter *** first collected the Moderate-resolution Imaging Spectroradiometer ice surface temperature(IST)product from the National Aeronautics and Space administration to extract leads from the Antarctic waters and verified their accuracy through Sentinel-1 Synthetic Aperture Radar ***,a surface classification decision tree was generated for HY-2B satellite altimeter measurements of the Antarctic waters to extract leads and calculate local sea surface *** then estimated the Antarctic sea ice freeboard and thickness based on local sea surface heights and the static equilibrium ***,the retrieved HY-2B Antarctic sea ice thickness was compared with the CryoSat-2 sea ice thickness and the Antarctic Sea Ice Processes and Climate(ASPeCt)ship-based observed sea ice *** results indicate that our classification decision tree constructed for HY-2B satellite altimeter measurements was reasonable,and the root mean square error of the obtained sea ice thickness compared to the ship measurements was 0.62 *** proposed sea ice thickness algorithm for the HY-2B radar satellite fills a gap in this application domain for the HY-series satellites and can be a complement to existing Antarctic sea ice thickness products;this algorithm could provide long-time-series and large-scale sea ice thickness data that contribute to research on global climate change.

作者： Xianyong Zheng school of Business administration zhongnan university of economics and law {3. P.R.China Hanmin Huang school of Business administration zhongnan university of economics and law {3. P.R.China

Chinese needs of ironstone have been increased sharply since the new century. China has been the biggest buyer in the demanding market since 2003. But it’s puzzling that, the status of biggest buyer hadn’t given China sufficient authority of ironstone pricing since China entered the ironstone negotiation. The reasons are worth pondering. This paper will combine the related theory of bargain model to analyze the mechanism of ironstone negotiation and then to identify some of the reasons of defeat.

《行政许可法》对地方立法的影响

行政许可法颁布和施行的意义不仅仅局限于行政法治这一领域,而且以独特的视角为地方立法今后的发展提供了难得的参考。在地方立法理念上的变化体现为:平衡公益和私益,追求效益,立法应务实创新;对地方立法体制及立法技术的影响表现为:地方对行政许可设定具有很强的局限性,地方立法主体需重新认识和定位,注重以立法事项的性质确定立法主体,在权限上既赋予地方一定的专有立法权,同时对地方立法权进行一些具体的禁止作为补充,健全地方立法的具体内容,完善地方立法技术。即便如此,行政许可法仍对地方立法可能造成以下负面影响:首先是借行政许可法留下的可观的立法空间,扩大地方立法权;其次是由于行政审批改革与立法同步,立法中部门利益将会反弹。

Yunnan university of finance and Trade recording to t he statistics of chain’s output of tea, Yunnan province has entered the ranks of the larger ones of the production in China. Yunnan’s tea industry has the natur al resources and the economic effects envied, on the orther hand, Yunnan’s tea m arket has gradually become less and the economic effects have been poor. Through our comprehensive investigation and study, we consider that because the supply chain has seriously been disjointed among production, supply and sale of tea ind ustry in Yunnan, the supply chain of Yunnan’s tea industry need to be reorganize d for the promoting the development of Yunnan’s tea industry. The essence of reengineering of Yunnan’s tea industrial supply chain is to set u p the model of the trailed operation,to strengthen the strategic partnership man agement between the supply chain, to optimize the design of the supply chain and build up and improve the working mechanism for management of the tea industrial supply chain. The structure of Yunnan’s model of tea industrial supply chain: the model of com mercial flow; the model of logistics flow; the model of information flow and the model of cash flow. The solutions and policies for the reorganization of Yunnan’s tea industrial sup ply chain: planning, logistics and distribution and sales. Set up the supporting system of information technology. Build up the control system of production and *** the working mechanism of Yunnan’s tea industrial supply chain. Implement the engineering of exporting Yunnan’s tea into the markets of other p rovinces and foreign markets. Have many the channels that raise the funds of dev elopment for Yunnan’s tea industry.

台湾大学社会学系的林端教授于2003.出版的《韦伯论中国传统法律:韦伯比较社会学的批判》一书全面系统地批判了韦伯关于中国法律传统的论断。该书在社会学方法论上指出了韦伯比较社会学里二元对立的理想型比较的局限;在实质社会学分析上则结合学界对清代法律和司法审判的研究成果,说明了韦伯对中国传统法律与司法审判的看法存在误解与局限。在此基础上,林端教授认为,若要深刻理解中国法律传统,关键在于把握体现于其中的“多值逻辑”。

根据2008年全国老年人口健康状况调查数据(CLHLS),采用逐步回归模型和分组检验,重点分析医疗保障对老年人家庭医疗负担的经济影响,研究结果显示:医疗保障总体上对老年人家庭医疗负担具有挤出效应,即能减轻其医疗负担;医疗保障对老年人家庭医疗负担的影响有显著城乡差异,在城镇和农村中分别具有挤入和挤出效应;进一步分析发现该效应的群体性差异和非均衡性,即从城市到农村、从高收入到低收入家庭,医疗保障对其产生的挤入效应逐渐减小,挤出效应逐渐增大,根源在于医疗保障自身运作机制及卫生制度存在的各种弊病。最后在研究结论基础上提出建立公平、按需分配的医疗保障制度等思考。

The vulnerable eco-area is one of the important research targets in the field of sustainable development. It is the requirement of building a well-off society in an all-round way that we should study more on the vulnerable eco-areas, deal with the relationship between environmental protection and economic development, speed up the economic development in these areas and increase the living standard of the local people. This paper puts forward the countermeasures of environment---economy coordination, on the basis of the recognition of eco-environment features and social economic conditions in the vulnerable eco-areas of China, in view of the progress in sustainable development studies of the vulnerable ones, taking the transitional areas of farming and pasturing in northeast China as an example to study the regional environment vulnerability.

近年来,中国的国内生产总值和财政收入高速增长。中国政府为了实施依托科技和创新的战略,在研发经费支出上的投入也快速增加。本文利用协整检验的方法对1991年-2013.中国的国内生产总值、财政收入和研发经费支出的时间序列数据进行研究。分析结果表明国内生产总值与研发经费支出存在长期均衡关系,财政收入与研发经费支出也存在长期均衡关系。然后本文进一步运用ARIMA模型对中国和美国在可见未来的研发经费支出进行预测。结果表明中国的研发经费支出一直会跟美国有相当大的差距,且难以赶上美国。接下来,本文分析中国研发环境的下列三个缺陷:科研经费使用效率低,创新人力资源与经费不匹配,以及科技成果评价体系不科学。最后,文章给出改善中国研发环境的建议。
