受国家地震局科技监测司的委托,于三月五日至十二日在南京举办了国产小核旋仪(CHD 5和CHD 6型)改进技术推广学习班。共有14个省局(办、队)约30人参加了学习,由江苏省地震局磁电组张四维等同志主讲。局科技司毛桐恩同志曾来学习班指导,他在讲话中指出,目前地震系统有近千台国产小核旋仪,由于该仪器一般用于磁法勘探,灵敏度不高,稳定性差,问题较多,绝大多数闲置未用,迭成了大量的积压;若从国外引进地磁仪器,由于资金有限,只能是少量的,而研制新
Entrusted by the Science and Technology Monitoring Department of the State Seismological Bureau, a seminar on the improvement of technology promotion for domestic small-sized nuclear spinning machines (CHD 5 and CHD 6) was held in Nanjing from March 5 to March 12. A total of 14 provincial bureau (office, team) about 30 people attended the seminar, by the Earthquake Power Bureau of Jiangsu Province, Zhang Siwei and other comrades. Bureau of Science and Technology, Comrade Mau Tong En had come to learn class guidance, he pointed out in his speech, the current seismic system has nearly a thousand domestic small nuclear spinning instrument, the instrument is generally used for magnetic exploration, the sensitivity is not high, poor stability, more problems , The vast majority of idle unused, stacked into a large backlog; if the introduction of geomagnetic instruments from abroad, due to limited funds, only a small amount, and the development of new
