Teaching Materials of Geophysical Observation-Earthquakes and Geomagnetism-

1.自行研制的地震仪系统概述自1989年研制出样机以来，对自行研制的地震仪系统的改进一直延续至今。该系统是全手工制作的，包括地震仪、电路和自动测井软件。对系统的详细内容进行了描述，包括未发表的研究。为了便于制作像我的系统一样的仪器，我们对电路和自动测井软件进行了详细的说明。对学校地震观测中的一些注意事项也作了详细说明。由于我的系统太难在学校制作，我们开发了一种新的简化的传感器，它由胶片外壳和条形磁铁组成，并进行了详细的描述。制作用于地磁观测的磁通门磁强计使用铁氧体磁芯制作了磁通门磁强计，并对传感器的灵敏度和日变化的噪声水平进行了标定。开发了地震与地球结构教材软件，展示了地震波的传播过程和海啸的传播过程，为课堂教学提供了基于PC的数值模拟。地震图的例子--临近地震--5.以国外地震为例，介绍了一些有特色的地震图，并给出了有益的注解。

1.The outline of my own handmade seismograph systemImprovement of my own seismograph system has been continued since 1989 when the prototype had been made.These system is whole handmade including seismometers, electric circuits, and auto logging software The details of the system were described including unpublished study .We explain in detail about the electric circuit and the auto logging software for the convenience of making an apparatus like my system. Some notice points in the observation of earthquakes at school were explained in detail, too. Since my system is too dificult to make at school, we developed a new simplified sensor which consists of filmcase and bar magnet, and described in details.2. Making fluxgate magnetometer for geomagnetism observationWe made a magnetometer using a ferrite core and calibrated the sensitivity of the sensor and the noise level of daily variation.3. Softwares for the teaching materials about the earthquake and the earth structureSoftwares which show the propagation of seismic waves and the propagation of tsunamis were developed as PC based numerical simulation for study in the classroom.4. Exemples of seismograms -Near earthquakes-5. Exemples of seismograms -Foreign earthquakes-For the use of teaching material, some characteristic seismograms are shown with helpful comments.
