| 摘 要： | 根据TAI型库尔特计数器单管粒度分析结果,利用灰色系统建立GM(1,1)预测模型,对样品频率曲线进行外推处理,可获得小于仪器基线通道阈值颗粒的体积百分比含量,并将结果与入重-出重法测定结果进行对比,精度较高。为电敏感区法粒度分析资料的外推处理提供了新的方法。

| Abstract: | According to the results obtained from the particle size measurement of single orifice tube, using Coulter Counter Model TA I ,the GM(1,1) model of grey system has been established. It has been used to extrapolate the frequency curve of particle size of sediment samples. The accumulated volume percentage contains under the threshold value of the lowest channel of the instrument can be obtained. Through compared the result with that obtained from weight in-weight out method, we fond thatthis is a new method of estrapolation technique of particle size measurement using electrical sensing zone method. |
