目前用于地震观测的记录仪器,以可见笔绘记录仪最为普遍。这种记录管理和使用方便,提供地震数据直接快速,但同照相记录相比、前者记录笔尖所走轨迹为弧线,而后者属直线记录。因此笔式记录仪会对地震学动力参数带来误差.地震工作者希望改变这一记录形式,期望有一种较为理想的直线记录笔出现在地震领域中。
The current recording equipment for seismic observation is most commonly seen as a pen recorder. This record management and easy-to-use, to provide direct and fast seismic data, but compared with the photographic records, the former record pen tip to track the arc, while the latter is a straight line record. So pen recorders can cause errors in the seismological dynamic parameters.Seismic workers hope to change this record form and expect a more ideal linear stylus to appear in the field of earthquake.
