为了满足工程中各种振动测量的需要,陕西省建研所与四川省建研所、上海市建研所、同济大学组成了振动测试研制小组。经过对线路设计、结构设计,于1973年12月制成振动测量仪样机,又经国家计量科学研究院四川分院率定后,在各工程中进行实测考验,于1974年第二季度开始小批量生产;现投产的JZ-3型振动测量仪是在样机的基
In order to meet the needs of a variety of vibration measurements in the project, Shaanxi Provincial Institute of Construction and Research Institute of Sichuan Province, Shanghai Institute of Construction, Tongji University formed a vibration test development team. After the circuit design, structural design, made in December 1973 vibration measuring instrument prototype, but also by the National Institute of Metrology Sichuan branch rate set in the project after the test, in the second quarter of 1974 began a small batch Production; JZ-3 is now put into production of vibration measuring instrument is based in the prototype
