对于声发射技术我们是很陌生的。去年七月份接受生产单通道声发射仪器任务后,同合肥通用机械研究所共同研制了二台仪器。郑州会议以后,根据同志们的要求,我们又作了小的改动,最近准备小批试生产。现将仪器的电原理图和电器指标介绍给大家,希望提出宝贵意见,以便继续改进,更好的为用户服务。 For acoustic emission technology we are very strange. After accepting the task of producing single-channel acoustic emission equipment in July last year, it jointly developed two instruments with Hefei General Machinery Research Institute. After the Zhengzhou meeting, according to comrades’ requests, we made a small change and recently prepared a small batch of trial production. Now the instrument’s electrical schematic and electrical indicators introduced to everyone, hoping to come up with valuable advice in order to continue to improve and better serve our customers.
