Effect of these factors, in declining order, are filler content (f), square of factor f, factor v, factor θ, factor r, factor t, second order term of factor v and square of factor t.
· It is found that filler content and impact velocity are the two most influencing factors affecting the erosion rate of the composites.

These factors, as well as the roughness value of the pre-treated surface (e.g.
Friction factors are identified as follows: is the drug coefficient when the indenter starts moving; fr is the drug coefficient when the indenter moves at a constant speed, caused by plastic deformation of the surface layer of the workpiece and the adhesive properties of the contact "indenter – surface of the workpiece".
Y depth of the groove depends on the values of factors Rapre, r, Q, V.
Thus, force characteristics of the contact interaction are most affected by the factors of the part hardness and the processing speed.

Mechanical tests as tensile strength, flexural strength, impact strength, shore D hardness are used to learn about the properties of manufactured composites.
The result show increased the mechanical properties of the PMMA denture base material.
Impact Strength Test Result Two factors affect the specimen's efficiency: first, the reinforcement material's capacity to inhibit crack propagation by absorbing energy; and second, the reinforcement fiber and matrix's weak bonding, which results in micro-spaces and crack propagation[19] The values of the hybrid composite specimens' impact strength gradually decreased as the weights proportion of nZrO2 with GFs increased, starting at group A.

Microstructure is a important index of soil physical, mechanical and engineering properties, SEM images and computer image processing technology make the soil microstructure research developing rapidly in recent years, but the researches on the influence factors and important degree are rare.
Introduction Microstructure is one of the important index of soil, it can reflect formation conditions, and it also has important implications on soil physical, mechanical and engineering properties.
Information obtained by SEM analysis of the structural characteristics of the soil and its correlation with the physical and mechanical properties, is a core issue in today's microstructure and micro soil mechanics.
Regardless of soil in which research based on SEM will be affected by many factors of human and objective conditions.
There are few studies on these factors impact on soil structure and the impact of the weights.
