回顾自己之旅——一种新的旅游方式

随着人们物质文化生活水平的日益提高和旅游市场的开拓与发展，旅游者的旅游目的和旅游内容朝着多元方向发展，旅游形式也极为丰富多彩。近年来，利用节假日携带家眷再访旧居地的短期旅行，在日本的一些中年家庭中逐渐盛行起来，这一新的旅游方式，被日本记实文学作家足立伦行称为“回顾自己之旅”。     

电源浪涌保护器的参数选择及线路保护

市级气象台IT资源的整合方式和实践

气象台是气象部门IT资源最丰富的地方。根据株洲市气象台多年的改革实践，总结出IT资源的整合具有三个层次：基于硬件的整合，基于软件的整合，基于人才的整合。整合的目标是保证和促进气象事业的可持续发展。根据事业发展的需要，提出预报水平自组织进化系统——建立使短期天气预报水平不断提高的自组织系统，通俗地称之为天气预报值班系统。该系统包括集成研讨系统，客观、公正的预报水平考评系统和自组织的人才系统，经过6年的业务应用，取得了显著的业务效益和巨大的社会经济效益，实现了气象事业的可持续发展。     

普通物理教学改进探讨

目前在我校的普通物理教学中，进行理论教学的很多老师还是讲书本、讲习题的方式。虽然这样的方法曾经培养了一大批优秀的学生，但是面对更高的教学要求，还应该敢于开拓、不断进取，选取更好的教育方式来进行普通物理教学。     

针对学生差异 构建问题情境

新课程的精神实质要求变革学生的学习方式，使学生能够由被动接受式学习转向主动探究式学习，而这种探究式学习是建立在学生对地理问题探究和解决的过程中，因此构建地理问题情境无疑是学生主动探究学习的关键，为此地理教师必须主动更新理念，在教学中应该重视对桕建问题情境的探索和研究，从而通过教师自己的教学方式和教学的变革来带动和促进学生学习方式和学习行为的改变。     

关注教学衔接 加强学法指导

长期以来，初高中地理教学相对独立，信息传递和反馈渠道不畅。随着高中阶段课程改革的全面推开，新教材所承载的课程内容的不衔接现象，学生思维方式和智能发展要求跨度太大等问题逐步暴露出来。在发现并解决问题的过程中，我们应建立和完善初高中地理教学的沟通衔接，促进教师教学行为和学生学习方式的进一步转变和提高。     

Application of Load/Unload Response Ratio in the Study of Seismicity in the Region of Iran

The variation of Load/Unload Response Ratio (LURR) against time for earthquakes in Kerman Province, Iran, on February 22, 2005, M6.4 and in Lorestan Province, Iran, on March 31, 2006, M6.1, has been calculated and analysed in this paper. The tempo-spatial scanning of LURR in the region of Iran during January 1, 2003 to March 31, 2006 has been conducted, with 1 year as a time-window, 1 month as a time-step, and the comparison of the LURR anomalous regions in 2004 with the actual earthquakes with M≥5.0 in the next year (2005) is also given, which shows that 11 earthquakes with M≥5.0 occurred in LURR anomalous regions while 12 earthquakes with M≥5.0 in LURR regions in 2005. Furthermore, the seismicity in this region is studied by investigating the evolvement of the anomalous LURR regions.     

Recent Geochemical Variation of the Hot-Spring Gases from the Tianchi Volcano, Changbai Mountains, Northeast China

Recent fluid monitoring work shows that the contents of mantle-derived CO_2,He and CH_4 increased anomalously in 2002 and 2003. The 3He/4He ratio of the deep-fault-type Jinjiang hot springs increased highly anomalously in 2003, and then decreased in 2004. The 3He/4He ratio from the thermal-reservoir-type Changbaijulong hot springs increased slowly in 2003, and the increase continued in 2004. The mantle-derived He content of the He released from the Changbaijulong springs increased obviously in 2004. The anomaly of the released gases and the isotopic He was consistent with the trends of seismic activities in the Tianchi volcanic area between 2002 and 2004. The abnormal release of the Jinjiang hot springs apparently decreased after the seismic activities ceased in the second half of 2004, while the abnormal release from the Changbaijulong increased significantly after these seismic activities. It shows that the abnormal release of magmas-derived gases from the thermal-reservoir-type springs lags behind that of the deep-fault-type springs. These characteristics may be of great significance for identifying deep magmatic activity and predicting volcanic earthquakes in the future.
