In this study we applied the multiplicative decomposition model because it has been found to be useful when modeling time series that display increasing or decreasing seasonal variation [19, 20].
These demand peaks recur following almost a predictable pattern which concurs Busetti and Harvey [24] such that understanding seasonal fluctuations helps plan for sufficient goods and materials on hand to meet varying seasonal demand.

The arrow color represents the minimum speed that is 0 in the regional materials in the punch diameter deviation from the outside, which shows this area is basically no flow.
The outer materials in contact with the die wall are slower than the materials near the symmetry axis center and the difference between them will increase with the increment of extrusion capacity, the distance of end face at axial position between center layer and surrounding material is greater and greater, so that they will not be gradually in the same plane.
The metal materials of this region can flow to center axis of symmetry, however, with the increase of deformation degree, the surplus materials will be less and less between the punch-dies and flow properties of materials is gradually weakened to makes materials at surrounding of the die flow to the center difficultiy.
And the peripheral materials cannot supplement to the center part effectively.

Introduction
The blast-furnace process is currently one of the major parts of the repartition of iron ore raw materials.
For the solution, the Fourier differential equation is required to know the thermal conduction of materials of a lining.

Due to the continuous weathering of the earth's surface, silica sand is an extremely abundant and common natural material.
Moisture content is measured and controlled to ensure minimal casting defects associated with organic matter present in silica materials.

As a result of gravity, some parts of materials will be gradually deposited at the bottom of the crushing chamber, at this time the 1st fan 5 has brought out the high-speed airflow, and it can take out the materials, which is re-transported through the feed tube 6 to Room 2 to smash once again.
Let F be the new surface area when the material is smashed, then the rate of generation of new surface area is the crushed speed of material: (2) In the equation, —material crushing speed; —the coefficient related to crushing process; —the rate coefficient of crushed materials; —the coefficient related to crushing process; ; —material density.
