震源系统不稳定度指标和强震短临预报

在探讨震源系统不稳定产生的物理基础前提下，应用调制模式提出了利用小震日频次起伏加剧与外因的相关性进行强震的短临时间预报的设想，具体提出了调制小震频次起伏加剧的两个判别震源系统不稳定度的指标λ＿１和λ＿２。前者为单因子调制指标，后者为多因子调制或多因子调制强化指标。关于大震的地点预报，应用立交模式短临阶段出现调制小震通过未来大震的共轭小震活动条带进行预报。     

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

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.
