本文根据时域实时方法，对辽宁省共同台基的数字宽频带加速度记录和地震仪速度型记录进行相互仿真，并做了对比分析。结果表明，可以由加速度记录仿真得到真实的速度与位移时程；同样，地震仪速度型记录也能通过仿真得到加速度时程。由此可见，强震观测和地震观测在一定范围内是可以相互替代的。

The paper uses real time domain methods to simulate both wide band acceleration and velocity records from a base station in Liaoning Province, and compare them with the records by the instrument. The result shows that we can get actual velocity and displacement time histories by simulating wide band acceleration record. It can be concluded that strong motion observation and seismometer observation can he an alternative to each other to a certain extent.[著者文摘]
