Instrument for sediment measurement and particle size analysis in open channel 河流泥沙測(cè)驗(yàn)及顆粒分析儀器
The annular flume , which is an ideal instrument to study fine sediment , is restricted by the technology of sediment measurement 摘要環(huán)形水槽是研究細(xì)顆粒泥沙的理想裝置,但測(cè)沙技術(shù)的相對(duì)滯后極大地制約了環(huán)形水槽的使用。
Aiming at the change of the traditional sediment measurement method , a new equipment , called infrared back - scattering sediment instrument , is introduced , it can measure the real - time sediment content continuously 為改進(jìn)環(huán)形水槽的傳統(tǒng)測(cè)沙技術(shù),自主研發(fā)完全開放式的實(shí)時(shí)在線測(cè)沙儀器,力求在水槽中實(shí)驗(yàn)水樣的自然流態(tài)下實(shí)時(shí)測(cè)量垂線懸浮泥沙含量。
