对于研究液体中粒子的沉积速率,业已提出很多种不同的方法。这些方法中的大多数都是其于沉积——其上的清浮界面的位置相对时间的探测,而该界面往往是不易定义的,但是它却决定着悬浮小粒子的沉积速率。我们设计了一种超声干涉量度学方法,以便更好地研究液体中粒子的沉积。该方法基于A模式回波描记术的可用以测量当粒子沉积在一个固态盘上时形成的、被称之为“固态盘沉积”界面的一个固定界面11反射的超声波(回波E_1)的幅值。回波的幅值既取决于三介质(固态盘、
A number of different approaches have been proposed for studying the deposition rate of particles in liquids. Most of these methods are based on the relative timing of sedimentation - the location of the clear interface above it, which is often undefined, but which determines the deposition rate of suspended particles. We have devised a method of measuring interferometry in order to better study the deposition of particles in liquids. This method is based on the use of A-mode echography to measure the amplitude of the ultrasound (echo E_1) amplitude reflected by a fixed interface 11 called the “solid-state disk deposition” interface as the particles are deposited on a solid-state disk value. Echo amplitude depends on the three media (SSD,
