【摘要】 在野外进行地震监测是地震学的基础工作。地震监测设备的设计工作温度一般在-20℃以上,但高纬高寒地区冬季环境温度往往低于此温度。参照国外经验,基于我们在南极内陆和我国长白山低温地震监测的工作经历,对如何做好低温条件下的天然地震监测进行介绍。实践证明,对地震记录仪和电池等实施被动保温非常必要,持续供电能力则是连续地震监测工作成败的关键。更多还原

【Abstract】 Observation by seismograph is a basic work in seismology.Working temperature of seismograph is mostly-20℃,however,the environment temperature in most high-latitude or high-altitude regions in the winter is lower than the working temperature.In this paper,we introduced how to do seismic observation in a cold environment on the base of experiences from other countries and on the basis of our practices during seismic observations in Antarctica and Changbai Mountain,China.Passive thermal insulation on seismic datalogger and battery is an essential treatment;Capacity of power supply is another key factor determining whether seismic observation can succeed.更多还原
