Abstract：Particle materials are widely used in different fields such as medicine，construction，chemical and environmental protection, and the parameters of particle size，shape and distribution are closely related to the physical and chemical properties of particle materials. Particle testing technology is an important means to represent the parameters of particle. In recent years, the particle testing technology of different fields and principles has made new progress and obtained closely attention from various industries. This paper summarizes the development status of particle testing technology and its the latest application process in different fields. On the basis of this, the different trend of the particle testing technology is prospected, in order to provide appropriate reference for the application of particle testing technology in different fields.
