一、处仪修站和四川大学共同协作,今年进一步完善了地震载波传输整机的设计工作,并对各单元电路的性能进行调试。将试制的载波装置与地震仪配合进行了室内和野外试验。1、载波道传输试验(1)第一次试验是4个检波道(未加变放和屏蔽),传输信号80赫。第二次试验是6个检波道(未加变放和屏蔽),传输信号36赫。当输入为100微伏～400毫伏时,能不失真地传输,但当输入小于100微伏时,特别是小于40～30微伏的小信号传输,感应背景很明显。(2)进行7个检波道试验(未加变放),加了比较简单的盒子屏蔽,录制的记录有很大改进。
First, at the instrument repair station and Sichuan University work together to further improve the design of seismic carrier transmission machine this year, and the performance of each unit circuit debugging. The trial of carrier devices and seismometers with indoor and field experiments. 1, Carrier transmission test (1) The first test is 4 detector channel (without amplification and shielding), the transmission signal 80 Hz. The second test is six detector channel (without amplification and shielding), the transmission signal 36 Hz. When the input is 100 micro-volts to 400 millivolts, can be transmitted without distortion, but when the input is less than 100 micro-volts, especially small signal transmission of less than 40 to 30 micro-volts, the sensing background is obvious. (2) 7 channel test (no amplification), plus a relatively simple box shielding, recording the recording has been greatly improved.
