珠江水利委员会由美国进口的305型海洋工程地震反射剖面系列,在地矿部第二地质调查大队的帮助下,经过对仪器的验收、调试,以及在海上进行航拖试验,已取得理想的试验结果。目前已在珠江河口及其近海地带正式投入生产使用。 305型海洋卫程地震反射剖面系列由:600型海洋声电源,105型电火花发射系列;20型多用的水上拖缆系列,300型高分辨率地震放大器;LRS—1307M线性扫描记录器等五部分组成。地震源是严密封装在轻便的防护箱内,其它部件可
Pearl River Water Conservancy Commission imported from the United States Model 305 offshore engineering seismic reflection profile series, with the help of the Second Geological Survey Brigade of the Ministry of Geology and Mineral Resources, after the acceptance of the instrument, commissioning, and air-drag test at sea, has made the ideal test result. At present, Pearl River Estuary and its offshore areas have been formally put into production. 305 series of marine seismic seismic reflection profile by: 600 marine acoustic power, 105 series of spark discharge; 20-type multi-purpose water streamer series, 300 high-resolution seismic amplifier; LRS-1307M linear scan recorder and other five Part of the composition. The source of the earthquake is tightly encapsulated in a lightweight protective enclosure with other components available
