BT-1500离心沉降式粒度分布仪比测分析及其应用

摘要

对西洞庭湖水系的安乡、自治局（二）、石龟山、官垸4个水文站62个泥沙颗分细沙部分（粒径小于0．062mm）水样样本，用传统的吸管法和BT-1500型离心沉降式粒度分布仪法进行同粒径级比测分析，介绍率定仪器参数和确定误差标准的基本方法以及在应用过程中注意的事项，供泥沙颗粒分析工作者在实际分析工作应用中借鉴。%Through selecting silver-sand water samples of 62 sediment grains from 4 hydrologic stations： Anxiang station, Autonomous Council （II） station, Shigui Mountain station and Guanyuan station which belongs to West Dongting Lake water system and using traditional pipette method and decanter grain- size distribution meter BT-1500 to do comparing test and analy- sis, the author introduces rating instrument parameter and definite error standard method to sediment grain analysts.
