The ultrasonic measurement results are compared with light extinction method measurement, which shows this method has a good foreground for particle sizing. 测量结果与消光法测量进行对比,表明该方法应用到颗粒粒度大小测量是切实可行的。
The presence of stray light is indicated by the absence of complete extinction when the phase difference is such that this should be achieved. Vis Spectrophotometer Wavelength Error of the Measurement Results Show the Evaluation of Uncertainty 若位差达到应当消光的程度,却未能完全消光即表示有杂散光存在。可见分光光度计波长示值误差测量结果的不确定度评定
