Introduction
Currently on the particle shape and morphology of a variety of qualitative and quantitative representation of different methods, even for this term in terms of size, there is no
Uniform definition. Different particle size analysis methods are based on the measurement of different physical characteristics. In GB/T 15445.1, the particle size is defined as
Diameter of the sphere having the same physical characteristics, i.e., equivalent spherical diameter. The so-called characteristic function, which is characterized with the primary concern (for example, flow
Mobility, taste and dissolution time) associate.
In terms of particle characterization, widely used classification method showed that the particle size is usually an important indicator, but not only the particle size
Sufficient to explain the phenomenon of particles such as powder flow, mixing, wear or biological effects. Particle system, particle shape and morphology play focuses
To the role, it is necessary for quantitative characterization of these features and descriptions.
Characteristic function contains additional shape parameters should have better attributes associated with a particular particle system. For example, the characteristic function by using
Grain size and edge sharpness of information, not only to distinguish between old and new abrasive grains, but also quantitative forecast abrasive grinding effect.
GB/T 21649.1 and ISO 13322-2 respectively measuring particle size analysis of static and dynamic images, descriptive and verification
The method provides guidance. Standard wide range of industrial applications of image analysis techniques required particle size, shape and other characteristics of geometry and measurement
method.
Shape of the particles is the envelope surface at all points on its surface composition. Particle morphology is simple shapes to complex description description (such as porosity, crude
Roughness and texture and other features) extension.
There are a variety of terms set for the description of particle shape and morphology (see Chapter 5), which may describe particle classification or identification
Helpful, but the definition of particle shape and morphology quantitative terms in the software applications required has not yet reached sufficient consensus, this part of the repair
Order version will involve relevant content.

1 Scope
GB/T 15445 provisions of this part of the rules and terms of particle shape and morphology of qualitative and quantitative statements.
Note 1. In order to particles or systems more fully described granular information may be used together with other information, but in most cases can not be replaced.
Note 2. The samples of all the particles in the shape of an equivalent process has great limitations, it must be distributed as a supplement to other particle characteristics of particle size distribution
(See GB/T 15445.1).
Note 3. The technology is a decisive factor in selecting the appropriate particle shape characterization methods. Therefore, this section is limited to industrial applications and physical properties relevant to a
These characterization methods.
Note 4. The shape and morphology are usually three-dimensional problem, but due to the extensive use of image analysis, most of the definitions in this section are actually based on two
Dimension.
Note 5. Using the evaluation criteria in Chapter 4, Chapter 5 from various descriptors and methods to give a basic set of descriptors (see Chapter 8), which makes Chapter 6
Subject to the conditions discussed, can be of different shape analysis apparatus or a method for direct comparison.
