Introduction
Many cumulative particle diameter distribution system Qr (X), in a dedicated graph paper, it is represented as a straight line. FIG longitudinal and transverse
Coordinate conversion performed by various mathematical formulas. In this section, the cumulative size of the particles is assumed that the system obeys lognormal probability distribution.
In this section, a particle diameter of x, with the diameter of the ball is represented; Depending on the circumstances, the particle diameter of x, may also represent
The equivalent diameter is some other form of particles.

1 Scope
GB/T 15445 in this section is to particle characterization lognormal probability distribution of the particle system provides cumulative particle size distribution obedience
Theoretical basis, can clearly verify the distributed computing function made of particle size.
This section explains the lognormal probability graph paper design and moments, median diameter, mean particle size and volume - than the surface area of \u200b\u200bcomputing
method. Lognormal probability distribution is often applied to express the cumulative particle size distribution of any dimension.
This section applies to the number, length, area, volume or mass cumulative distribution of the reference characterization can be by a series of parallel lines table
It shows, and from any location in a line can be known to determine the location of all other lines.
