Dynamic Analysis of Micron-size Particles by Dynamic Ultrasound Scattering Method and Its Application

一种新的技术，使用超声波已经开发，以评估微米级颗粒的直径。与光学技术不同，这种方法允许人们在不稀释高度浑浊的悬浮液的情况下评估颗粒结构和动力学。在这项研究中，沉积速度和它的波动分别从平行和垂直于重力方向评估。将速度进一步转换为分散在水中的颗粒的直径。

A novel technique using ultrasound waves has been developed in order to evaluate the diameter of the micron-size particles. Unlike the optical techniques, this method allows one to evaluate the particle structure and dynamics without dilution of the highly turbid suspensions. In this study, the sedimentation velocity and its fluctuations were respectively evaluated from the directions parallel and perpendicular to the gravity. The velocity was further converted to the diameter of the particles dispersed in water.
