BCJY—Ⅱ型地震仪,是为适应深地震测深需要而研制的三分向模拟磁带地震仪。经辽宁省地震大队1984—1986年实验观测和野外使用结果表明:该仪器主要性能(三分向、自动操作、时间服务、)达到或优于国内同类仪器的水平。是目前地壳深部探测较理想的仪器。
BCJY-Ⅱ seismograph, is to adapt to the needs of deep seismic sounding developed three-point analog tape seismograph. According to the experimental observation and field application of the 1984-1986 earthquake brigade in Liaoning Province, the results show that the main performance (three-point, automatic operation, time service) of the instrument reaches or exceeds the level of similar instruments in China. It is the ideal instrument for deep exploration in the crust at present.
