 [PDF]

中文, 谭国良, 李国文
Journal of Water Resources Research (JWRR) , 2014, DOI: 10.12677/JWRR.2014.36057
Abstract:
鄱阳湖流域占江西省国土总面积的97.2%,占长江控制流域面积的9%,鄱阳湖流域水资源变化对长江流域有着显著影响。本文通过分析鄱阳湖流域降水、径流等水文水资源要素,得出了各要素的年际、年内及地域空间上的变化规律。同时,采用Mann-Kendall (MK)方法,分析鄱阳湖流域隆水量以及各站年入湖径流的变化趋势。
Poyang Lake basin accounts for 97.2% of total land area in Jiangxi Province and 9% of Yangtze River basin, and the change of water resources in the Poyang Lake significantly affects Yangtze River drainage area. In this study, the inter-annual, intra-annual and regional variation rules of each element were obtained through analyzing precipitation, runoff and other elements of hydrology and water resources in the Poyang Lake basin. Meanwhile, the Mann-Kendall (MK) method was used to analyze the precipitation of the Poyang Lake basin and the significance level of variation trend of annual inflow in each station.

Abstract:
鄱阳湖为长江中下游洪涝灾害频繁的地区,鄱阳湖洪水预报方案研制对于科学调度鄱阳湖防洪减灾具有重要意义。本文分析了鄱阳湖洪水及其灾害特征,根据星子站实测水位与星子、湖口站前期水位、涨率、区间平均降雨量、五河七口入湖流量与湖口出流量之差进行相关分析,建立了湖泊水量平衡方案与多要素相关方程两种预报方案,用于鄱阳湖洪水作业预报。通过历史资料和应用检验,这些洪水预报方案可以取得较高的预报精度。
Poyang Lake, located in the middle and lower reaches of Yangtze River, is the area that bears fre-quent flood disasters. The development of flood forecasting scheme for the Poyang Lake is of great significance for the scientific flood dispatch and disaster reduction. This study analyzes the cha-racteristics of flood and disaster of the Poyang Lake. Related correlation analysis was carried out based on the actual measured water level of Xingzi station, water level at earlier stage of Xingzi station and Hukou station, rise rate, regional average precipitation, the difference of flows into five rivers and seven stations and outflow of Hukou station. The lake water balance and multi- factor correlation equation schemes were established for flood forecasting. The floods of the Poyang Lake could be scientifically forecasted by these two schemes with relative high accuracy.

Abstract:
2009年三峡水库已经转入全面运行期。本文通过对1950年以来湖口站水位流量资料进行分析结果表明:近60年来湖口站年平均水位和平均流量虽然总体上略有下降,但是变化幅度不大且具有较明显的周期性。2003年以后变化幅度较大,尤其是2006年之后下降趋势十分显著。为进一步分析三峡水库运行调度对鄱阳湖湖口水文情势产生的影响程度,根据三峡水库运行调度情况对湖口水位流量在不同运行期进行了分析。结果显示水库蓄水期由于减少了长江干流流量,长江干流水位较天然情况下降低,湖口出流加快;在枯水期使得湖口站的枯水期提前,枯水期持续时间增长;洪水期和泄水期对鄱阳湖湖口影响不大。
The Three Gorges Reservoir had shifted into comprehensive operation stage since 2009. This paper analyzed daily water level and discharge data of Hukou station from 1950 to 2009. The results show that the average annual discharge and water level of Hukou station decrease slightly in the past 60 years and the changes show obvious pattern of periodicity. From 2003, especially after 2006, the average annual discharge and water level have declined significantly. According to the operation rules of Three Gorges Reservoir, this paper analyzed the hydrological impacts of Three Gorges Reservoir on Hukou hydrological regime in different operation periods. It is found that the decline of discharge and water level of Yangtze River caused by the water storing of Three Gorges reservoir leads to the dry season ofPoyangLakeappearing earlier and lasting longer. However, the influence on Hukou hydrological regime is not obvious at flooding and releasing periods.
钻孔灌注桩孔壁稳定性的影响因素研究
中文
公路交通科技 , 2011,
Abstract: 以某大型桥梁近接工程为背景,采用专业岩土工程有限元软件Plaxis,对钻孔灌注桩孔壁稳定性的影响因素进行了数值分析研究。研究结果表明若无邻近老桩基影响,孔径、孔深、泥浆相对密度、护筒深度及成孔时间是钻孔灌注桩孔壁稳定的主要影响因素;在邻近老桩基的影响下,护筒保护和护筒穿越土层的合理深度是可以将两邻近桩基相互影响降到最低的保证。以上研究结果的应用可提高钻孔效率,并可有效控制超近距离建(构)筑物桩基施工的破坏性影响,保证施工安全。
银行间资产清算顺序优化与风险传染免疫机制
中文
中国管理科学 , 2012,
Abstract: ?银行间交叉持有同业存款时,风险共担和传染是可能的。银行间市场结构的不同会对风险共担和传染产生影响,本文采用三阶段流动性偏好模型的一般分析框架,讨论了应对危机时银行微观层面的资产清算顺序的异同对于银行系统脆弱性的不同影响,并从合作博弈的视角探讨了"货币池"风险免疫的可能性。研究发现:在不存在银行资产信息不对称的条件下,当问题银行流动性波动足够大(ε>ε),银行间风险传染可能难以避免,而当流动性短缺ε在区间[ε,ε]内,银行间的合作博弈效果最优,风险传染可以在很大程度上避免。银行间市场的"货币池"免疫结构模式可以实现风险分担和防范银行间风险传染,从微观层面提供了一种银行间市场危机传染的内生免疫机制。
计时工资发放中的陷阱
中文
财会月刊 , 2013,
Abstract: 目前许多企业都采用计时工资发放标准,如果是按单一的“工时×单价”计算,不会造成员工利益受到损害。但是,如果计时工资要采用平均发放,或者设定一些条件和标准,在员工没有达到标准进行扣除时,由于计发标准和扣除标准不一致,或者偷换概念,则会使员工利益受到损害。本文结合企业实际案例对问题产生的原因进行分析,同时提出简单合理的计算方法,解决了差异问题。【关键词】计时工资平均发放差异分析企业计时工资发放是较普遍的事情,从一般角度看,只要正确统计了工作时间,事先明确小时工资单价,是不会出现问题,但是现实未必如此,从下面的实际计时工资发放案例中你能找出问题的原因吗?一、案例分析例:小张是一名有专长的技术人员,被一家企业聘用,采用计时工资,工资单价50元/小时,因为企业经营的特殊性,有淡季和旺季之分,一年只需要工作10个月,分为上下半年。上半年集中在2、3、4、5、6月,下半年集中在7、8、9、10、11月,为了计算方便,规定5个月按20周算。由于工作性质的特殊性,单位规定了半年内(即20周内)小张必须完成额定工时240小时,非工作时间小张必须留在单位等待突发的工作,但不计发计时工资以外的基本工资。企业为了让小张安心工作,淡季1月和12月享受工作月份的平均工资带薪休假。如果单位订单多,超过240小时,还是按50元/小时计酬,多干多得。但是5个月内工时不到额定240小时要按单价扣除,即扣除短欠工时×50元/小时工资。工资平均发放,半年一结算。具体发放计算方式如下:

高职高专大学英语改革探析——基于PBL教学模式和职业能力测试的应用
On the Reforms of College English Teaching in Vocational Schools—Based on the Application of PBL Teaching Mode and Vocational English Testing System
 [PDF]


Advances in Education (AE) , 2015, DOI: 10.12677/AE.2015.56035
Abstract:
当前经济的快速发展、社会的需求要求我们的职业英语教育与职场贴合,而学生的兴趣爱好则需要我们在教学模式和教学设计上做足功夫,激励学生思考和自主学习能力,并且用符合其职业要求的评价体系评估学生的英语应用能力。这些需要我们对高职英语教育进行再思考。
The fast development of social economy requires vocational English education to meet the needs of professions, while the interests of students make teachers more concerned with the ways to stimulate them in logical thinking and self-study, and in the meantime, to evaluate their ability in language application. Teachers should reflect deeply on the status quo of vocational English edu-cation and how to solve those problems.
