摘要
基于对台式和浸入式两种光电测沙仪的对比测试及对实测153组数据的回归分析,率定了含沙量与有关影响因素的相互关系,给出了 ZD-1000型仪器的率定公式。公式显示,含沙量不仅取决于水体浊度,还与泥沙的粒度参数(中值粒径、四分位离差等)有关。成果指出,针对实际情况做好率定工作后,光电测沙仪的实用性是肯定的。
Based on the contrast tests for both desk type and submerged type of the photoelectric gauging sand instrument,and by the help of regression analysis for 153 sets of data observed,the relationsihp between the sediment content and sever- al effective parameters are determined,and some formula appropriated to ZD-1000 Instrument are given.The formulae show that sediment content is related to not only turbidity of flow,but also grading factors (mid-diameters,quartile devation, etc) of sediment.All he results indicate that applicability of photoelectric gauging sand instrument is in the affirmative.
