中国科学院山西煤化所和山西省水文总站共同研究的超声测沙新技术,于1987年11月17日由山西省科委主持通过了鉴定.参加鉴定会的有水文、水利、声学、地学等各方面的专家和技术人员.与会代表认为:“超声测沙法与常规法相比,不仅改进了常规法笨重、繁琐、复杂的工作过程,提高测量精度,节省人力物力,降低劳动强度;而且可以连续观测悬沙脉动及变化过程和全面动态变化.超声测沙法与振动法和同位素法测沙相比,具有结构简单,体积小,重量轻,造价低,携带方便,无需人身防护等特点”.所研制的样机测沙范围为2—500kg/m~3.测量精度在5—50kg/m~3,相对
Chinese Academy of Sciences, Shanxi Coalification Institute and Shanxi Provincial Hydrological Station joint study of ultrasonic testing sand new technology, in November 17, 1987 by the Shanxi Provincial Science and Technology Commission presided over the identification. Participate in the identification of hydrology, water conservancy, acoustics, geosciences, etc. Experts and technicians in the conference held that: "Compared with the conventional method, the ultrasonic sand measurement method not only improves the heavy, complicated and complex working process of conventional method, improves the measurement accuracy, saves manpower and material resources, and reduces the labor intensity, but also can continuously Compared with the vibration method and the isotope method to measure the sand, the ultrasonic sand measurement method has the characteristics of simple structure, small volume, light weight, low cost, convenient carrying and no need of personal protection. The prototype developed by the scope of the sand is 2-500kg / m ~ 3. Measurement accuracy of 5-50kg / m ~ 3, relative
