Abstract:
二十世纪中叶的齐鲁大地,儒家的宁静早已不在,此时的齐鲁大地战火纷飞,百姓苦不堪言,让我们深挖中国大陆战场旧地的点点滴滴,直抵台湾核心地区,探访东瀛之地,用以还原蒙在历史表面上的战争内幕,重现中国抗战勇士的铁血豪情;揭晓国仇家恨背后的诸多历史细节,再现中华民族痛击日寇的义薄云天。历史纪录片《台儿庄一九三八》,以深邃悠扬的历史情怀、厚重朴实的民族感情,充分展现了伟大的中华精神,全面呈现抗日战争期间,中华儿女在台儿庄一战中,可歌可泣的浴血奋战。
In the middle age of 20 century, the quiet of Confucianism no longer existed in Shandong province and people suffered from the fighting everywhere. Now, we seek the details of the old battlefield on the mainland. After the arrival to the kernel spot of Taiwan and Japan, we try to reproduce the blood and iron spirit that have been covered by the war, discover the details of history from the disgrace of nation and the family feud and reproduce the righteousness while Chinese fighting the Japanese invaders. The history documentary Taierhzhuang 1938 fully presents the great Chinese spirit with the melodious deep history feelings and nation feelings and presents the Chinese war-riors’ fighting in the bloody battle in Taierhzhuang.

Abstract:
利用江苏省13个地级市2004~2013年的统计数据,通过面板数据模型,研究了水利基础设施对江苏经济发展的影响。研究表明:水利基础设施是经济发展的重要因素之一;进一步增强农业水利基础设施并不能给江苏经济带来正向促进作用,而发展与工业化与城镇化相关的水利基础设施能给江苏经济发展提供动力;苏南、苏中、苏北地区由于经济发展水平的不同,水利基础设施对经济发展的影响也有差异。
Through using 13 cities’ statistical data in Jiangsu province in 2004-2013, by panel data model, this paper studies the influence on the economic development of Jiangsu water conservancy infra-structure. Research has shown that water infrastructure is one of the important factors of economic development. The construction of agricultural water conservancy infrastructure cannot play a positive role in promoting economy in Jiangsu province, but the development of water conservancy infrastructure associated with industrialization and urbanization can promote the development of economy. Because of the different levels of economic development among southern, central and northern Jiangsu, the influence of water conservancy infrastructure on economic development also varies.

Abstract:

为提高测试效率、降低测试代价,提出了一种基于故障字典与分支定界相结合的模拟电路测试点优化方法。以模糊集和故障字典为工具,以故障检测、故障隔离为约束,建立了测试点优化的0~1规划数学模型,并用分支定界法求解,最后用经典的测试优化电路对该方法进行仿真验证。仿真结果表明:上述方法在保证故障诊断需求的前提下实现了测试点快速优化,为实施测试提供了指导。
To improve test efficiency and reduce test cost, an optimization method for test-point of analog circuit based on fault dictionary and the branch and bound is proposed. By the tool of fuzzy sets and fault dictionary, the 0-1 programming model for test-point optimization is established with the constraints of fault detection and fault isolation and the model is solved by the branch and bound method. Finally, the method is verified by simulating on the classic test optimization circuit. Simulation results show that the above method achieves a rapid optimization on the premise of ensuring the fault diagnosis needs and that it provides guidance for the test implementation.

Abstract: 随着信息技术的迅猛发展,服务业产业结构升级进程加快,电子商务将深度融合一、二、三产业发展,有效重构产业链条,推进一、二、三产业转型升级。电子商务快速发展,对于优化资源配置、推动产业供给侧结构性改革,加快转变产业发展方式,提升区域经济实力具有重大意义。本文基于CII发布的电子商务发展指标体系,构建电子商务发展水平评价模型,综合应用统计方法深入分析我国电子商务发展水平。结果显示:广东省电子商务发展水平最高,江浙沪京次之,其他城市居中,而青海、宁夏、云南、甘肃、西藏电子商务发展水平最弱。本文提出相关对策建议,促进我国电子商务产业跨越式发展。
With the rapid development of information technology, services accelerated upgrading of industrial structure, E-commerce will deeply integrate the first, second and tertiary industries, effectively re-modeling industry chain and promoting the first, second and tertiary industrial upgrading. Speeding up the development of E-commerce, it has a great significance on optimizing the allocation of resources, promoting the reforms of industrial supply-side structural, accelerating the transformation of industrial development and enhancing the strategic initiatives of the regional economy. Based on the CII release index system for development of E-commerce, this paper analyzes the characteristics and the level of development of E-commerce in China, and uses the statistical methods comprehensively to make an in-depth analysis of the level of e-commerce development in China. The results show that the highest level of e-commerce development is in Guangdong Province; Jiangsu, Zhejiang and Beijing are the next, followed by other cities, while the level of e-commerce development in Qinghai, Ningxia, Yunnan, Gansu, Tibet is the weakest. This paper presents relevant countermeasures to promote the e-commerce industry development by leaps and bounds.

Abstract:
海水中放射性铯的活度浓度必须通过吸附浓缩后才可以测量,缩短吸附浓缩技术的时间是提高采样时空分辨率的关键因素。课题组于2014年7月和11月对厦门近岸水体进行调查,分别利用实验室沉淀法和现场快速富集法分别对所调查海域水样中的放射性Cs-137进行测量,并针对体积对结果误差及方法探测限的影响进行研究。结果表明,两种方法得到的结果在同一数量级水平,2014年7月航次二者的一致率为66.7%,2014年11月航次二者的一致率为46.7%。体积在1000 L以内时,数据结果的误差和方法探测限均随体积增大而明显减小,综合考虑,现场快速富集法中过滤海水体积应不小于1000 L。
The activity concentration of radioactive cesium in seawater must be measured by adsorption concentration, and the time to shorten the concentration of adsorption is the key factor to improve the spatial and temporal resolution of sampling. Research group surveyed the coastal waters of Xiamen in July and November 2014, using the precipitation method and the on-site rapid enrichment method respectively for the measurement of radioactive Cs-137 in sea water samples, and aimed at the volume, the results error and method detection limits were investigated. The results show that the results obtained by the two methods were at the same magnitude level, the consistent rate being 66.7% in the July 2014 voyage and 46.7% in November 2014. When the volume is less than 1000 L, the error of the data and the detection limit of the method are obviously decreased with the increase of the volume, so that the volume of filtered seawater should not be less than 1000 L using the on-site rapid enrichment method.
冬季北半球Hadley环流圈的增强及其与ENSO关系
,李建平
自然科学进展 , 2007,
Abstract: 对1948—2005年冬季(12月—次年2月)的质量流函数进行了经验正交分析(EOF),结果显示其主要是由两个空间模态组成,即关于赤道非对称和对称模态.进一步分析表明这两个模态具有明显不同的时间变化特征,它们分别代表了冬季北半球Hadley环流圈在年代际和年际尺度上的变化.非对称模态的时间系数(定义为非对称模态的强度指数AMI)呈现出显著的年代际增强趋势,表明该模态对北半球冬季Hadley环流圈在最近几十年的增强具有显著贡献.同时它还与热带海洋,尤其是印度洋到西太平洋暖池地区的海温相关显著.而对称模态时间系数(定义为对称模态强度指数SMI)主要体现了Hadley环流在年际尺度上的变化,它与ENSO之间的相关系数在整个时段都是显著的.结果还显示:冬季北半球Hadley环流与ENSO之间的相关系数在20世纪70年代中后期发生的年代际突变也很可能是由于非对称模态引起的.

核农学报 , 2014, DOI: 10.11869/j.issn.100-8551.2014.03.0546
Abstract: 为了探讨适宜的绿豆耕作方式,增加绿豆的产量以获得更高的经济效益。以绿豆白绿6号单作为对照,考察了白绿6号分别和谷子、玉米间作对其生育过程中的多种生物性状的影响,研究了间作方式与绿豆成熟后的产量及产品品质之间的关系。结果显示间作对绿豆不同生育期的生物性状有着不同的影响,并导致了最终产量及产品品质的不同。在苗期,间作方式的影响并不明显。从拔节期到开花期,绿豆和谷子间作在株高、叶面积和单株干物质重等性状上体现出了一定的优势。在成熟期,绿豆和谷子间作对单株荚数、单株产量、单荚粒数、百粒重、分枝数等性状上的影响体现的更加明显。绿豆和谷子的间作方式最终实现了绿豆的增产,产量达到了1404.48kg·hm-2,相比绿豆和玉米间作方式下绿豆的产量提高了30.3%。同时,绿豆和谷子间作可提高绿豆中粗蛋白的含量,降低脂肪的含量绿豆和谷子间作可以实现增产的目的,并可以提高作物品质,显示了此种耕种方式的优势,宜在生产实践中采用。
