现金流量表用于企业财务分析的实证研究

现金流量表是通过会计期间营业所得现金收入减除需用现金支付的费用以后的余额来说明企业财务状况的变动。比起营运资金即流动资金净额来，现金的增减变动更能反映企业的财务状况和偿债能力。为了说明现金流量表对于企业财务分析的重要性，通过一个企业的现金流量表实例，分析了该企业的生产经营状况，结果表明，这种分析具有较强的实用性。

利用火箭技术对大型油罐进行模拟地震试验

利用火箭技术设计一种火箭激震装置，地震波动运动，其地震波主频率为２－１０Ｈｚ，持续时间达３ｓ，地面破坏状况相当于地震烈度７度。使用这种装置激震储存石油的大型油罐，可以检测储油罐的抗震性能。     

考察德国大学物理教学的启示

通过对德国克劳斯塔尔工业大学物理教学的考察，阐述了教学与科研相结合对提高大学物理教学质量的重要性。为寻求教学与科研相结合的途径和改变基础课教师长期脱离科研的现状，在分析我院物理课教学情况的基础上提出了几点建议和想法：首先，我院理学系除了下设物理教研室、物理实验室之外，可以设立研究室或科研课题组；其次，可以结合物理实验教学搞科研；还可以与其他专业合作搞科研。

在大学综合英语课堂教学中提升学生学习自主性的行动研究

通过采用行动研究的方法,揭示大学生英语学习中自主性问题的现状,并试图在教学实践中探索出有效的提升大学生英语学习自主性的方法。通过问卷、访谈、课堂观察等方式展开调查,并在分析和实践中发现,只有教师不断地激励,并在课堂上创设能够让学生发挥学习自主性的情境,开展多样的课堂活动,学生的英语学习自主性才会不断地提升,英语学习才会呈现出良性发展的态势。     

Solar Wind Models from the Sun to 1 AU: Constraints by in Situ and Remote Sensing Measurements

There are three major types of solar wind: The steady fast wind originating on open magnetic field lines in coronal holes, the unsteady slow wind coming probably from the temporarily open streamer belt and the transient wind in the form of large coronal mass ejections. The majority of the models is concerned with the fast wind, which is, at least during solar minimum, the normal mode of the wind and most easily modeled by multi-fluid equations involving waves. The in-situ constraints imposed on the models, mainly by the Helios (in ecliptic) and Ulysses (high-latitude) interplanetary measurements, are extensively discussed with respect to fluid and kinetic properties of the wind. The recent SOHO observations have brought a wealth of new information about the boundary conditions for the wind in the inner solar corona and about the plasma conditions prevailing in the transition region and chromospheric sources of the wind plasma. These results are presented, and then some key questions and scientific issues are identified. This revised version was published online in June 2006 with corrections to the Cover Date.

Capacity-building programmes in Latin America

We review how capacity building in space sciences has developed in several Latin American countries, the state of development of some current programs and the role that space activities and space information play and can play in the future. We stress the need to educate educators, in order to increase the public awareness about the benefits of space research and, more importantly, attract the next generation of professionals that will be required in the coming decades.     

16MnR低合金钢管板带极堆焊工艺研究及应用

某裂解反应器设计压力0.94MPa,设计温度340℃,工作介质为甲醇、氢、一氧化碳等,换热器管板基体材料为16MnR低合金钢。为提高设备抗高温氢、一氧化碳等介质的腐蚀性能,要求在其表面堆焊耐蚀不锈钢堆焊层。因此,管板不锈钢堆焊质量是整个换热器制造的关键。本文通过对焊接方法、材料及工艺的选择等方面的研究确定出最佳的焊接工艺规范参数。试验证明此工艺方法合理、可行,施焊效果良好,各项试验结果均符合设计技术要求。
