目前在我国的地震台站或流动磁测中,小核旋仪仍是主要的测量仪器之一。几年来,地震系统各单位在改进现有小核旋仪器的工作中都做了大量工作,并已收到可喜的效果。我们在改装小核旋仪器工作中体会到,要将仪器改装成自动记录,自动定时线路是造价较高的部分之一。为降低定时器造价,简化其线路,扩大定时范围,提高定时精度,我们对CHD-6型核旋仪进行了改进,并装配成自动极化开关和钟控自动打印装置,用于流动磁测日变形态观测。
At present, in our country’s seismic stations or mobile magnetic surveys, small nuclear spinning instrument is still one of the main measuring instruments. In recent years, various units in the seismic system have done a great deal of work in improving the existing small-scale nuclear spinach equipment and have received gratifying results. We are working in the modification of small nuclear spin instruments experience, to be converted into automatic recording equipment, automatic timing circuit is one of the higher cost. In order to reduce the cost of the timer, simplify its circuit, expand the timing range and improve the timing accuracy, we improved the CHD-6 type nuclear rotation device and assembled it into an automatic polarization switch and a clocked automatic printing device for mobile magnetic measurement Daily deformation observation.
