The effects of the non-breaking surface wave-induced vertical mixing on the forecast of tropical cyclone tracks

The Weather Research and Forecasting model(WRF)is configured for the region of(15°–41°N,105°–135°E),which covers the same area with the MASNUM(Key Lab.Marine ScienceNumerical Modeling,State Oceanic Administration)wave-tide-circulation coupled operational forecast system.Three numerical experiments are implemented to investigate the effects of the real-time forecasted sea surface temperature(SST)and the nonbreaking wave-induced vertical mixing(Bv)on the track forecast of all 33 tropical cyclones(TC)in the model domain area during 2008 and 2011.The first experiment employs NCEP FNL(NCEP final analysis)SST as WRF’s bottom condition as the Control run,which is also the default setup of WRF.The second and third experiments use real-time forecasted SST from the MASNUM forecast system with and without Bv,respectively.The forecasted track results are compared with Japan Meteorological Agency’s best track data.For 24-h forecast,the averaged TC position error of Experiment with Bv is reduced by 9%compared to the Control experiment,while the forecasted track error of Experiment without Bv is reduced by only2%compared to the Control experiment.For the 48-h forecast,the averaged track errors are reduced by 10%and6%with Bv and without Bv compared to the Control experiment,respectively.These results suggest that the real-time forecasted SST can improve the performance of WRF in forecasting TC track,and the Bv plays an important role in reducing the forecast error of TC track.Comparatively,Bv can improve more on the track of stronger TC.     

我国社会组织立法的完善

进入新世纪以来，我国社会组织有了非常迅猛的发展，在促进经济发展、繁荣社会事业、参与公共管理、开展公益活动和扩大对外交往等方面都显示出越来越重要的作用。虽然在短暂的历史时空中我国已经逐步建立起一个等级序列的社会组织立法体系，但是，我国社会组织立法存在的问题仍然不容忽视。为了建设一个社会组织蓬勃发展、各尽其力、各展其才的开放型社会，需要尽快完善我国的社会组织立法，即与时俱进地变更社会组织立法的理念、相机行事地平衡社会组织的立法框架、切中肯綮地建设几项具体的制度。     

实验室制备乙酸乙酯的改进

对现有教学实验中乙酸乙酯教学实验进行改进,用强酸性苯乙烯系阳离子交换树脂作为催化剂催化合成乙酸乙酯.最佳工艺条件为:树脂催化剂用量5g,硫酸1mL,反应温度80℃~90℃,反应时间15min,乙酸:乙醇(1∶1.5);实验全部用时1~2小时,平均产率接近70%,非常适合用于有机化学教学实验中的乙酸乙酯的合成.     

试论我国二倍工资罚则的不足与完善

我国的二倍工资罚则存在以下争议:二倍工资的法律性质是劳动报酬还是赔偿;劳动者拒签,用人单位是否需要支付二倍工资;事后补签劳动合同,用人单位是否需要支付二倍工资;合同期满后未续签劳动合同,用人单位是否需要支付二倍工资.它在实施过程中存在以下问题:劳动者签订劳动合同的责任不明确;用工之日的内涵不确定;一个月签约宽限期的适用范围模糊;二倍工资支付的期限不具体.今后立法应当从以下几个方面加以完善:区别规定未签订书面劳动合同的责任;明确劳动者签订劳动合同的配合义务;明确规定二倍工资支付的具体期限;界定用工之日和宽限期的适用范围.     

The analysis of the legislation on health and safety in Britain

Health and safety is an integral feature of work and employment relations. The consequences of ill-health and danger have an untold impact on workers,on their personal life,on those who enter employment settings,and on the provision of services and goods. In a variety of ways,people attempt to establish minimum standards of danger and hazard to deal with these consequences in their workplace. This essay will firstly review and assess the important issues in the development of the legislation on health and safety at work in Britain,and then analyze the recent situation on health and safety at work in Britain according to some statistics and examples. Finally,it will conclude that Business will benefit from good management of health and safety at work.     

《水污染控制工程》实验教学方法改进初探

结合水污染控制工程实验教学中发现的问题,尝试采用增加设计性实验,简化实验指导书编写以及将小试和中试实验引入教学等改进方法。实践表明,这些改进方法可以大大提高实验教学的质量和效率,增强学生的实践能力。     

枉法仲裁行为刑事规制的正当性

《刑法修正案(六)》第20条确立了枉法仲裁罪,从该修正案的草案阶段开始至今,围绕该罪是否应该设立,社会各界一直争论不休。现在,枉法仲裁罪的确立虽已尘埃落定,但各种批评意见却愈发热烈,且直指该罪存废问题。纵观仲裁员刑事责任制度的价值诉求、理论基础、法律基础、现实条件及经济学依据五个方面,枉法仲裁行为刑事规制的正当性自然凸现。     

比较视野中的近代中国民间社团立法

近代中国的社团立法对民间社团产生了重要影响，且经历了复杂的变迁。通过比较《结社集会律》、《治安警察法》和《人民团体组织方案》的内容，对近代中国民间社团立法进行解读，从立法学的角度分析其局限性，对现代中国的社团政策、法规的制订有一定的参考意义。
