This paper studies the factors that affect the surface roughness on a Platinum deposited wafer after reactive ion etching (RIE) using a combination of CF4 and Argon gaseous.
All three factors gave negative effects.
Methodology A design matrix was designed using full factorial design of experiment (DOE) with four factors and one response.
Pressure can affect plasma uniformity and cause the etch rate or the deposition rate across a wafer to change.
Moreover, ion bombardment is a very important property of plasma.

For decades, the composite materials have been increasingly widely used in aerospace, ship, auto and civil engineering with its excellent mechanical properties[1].
All industries engaged in the national construction in China often come up against the problem that a mature composite material may be in short supply due to the market factor, price or other factors and thus affect the normal operation of the project.
It generally studies the large systems containing complex factors.
It’s feasible to give a qualitative and quantitative evaluation on the properties of the composites with AHP.
In this paper, the gray hierarchical analysis is applied to the relation evaluation of the properties of composites to take an overall consideration of several factors affecting the performance and avoid the subjectivity of the single factor.

Significant changes in mechanical properties were observed.
Analyzing these factors based on different models, it can be concluded that they all come down to similar conclusions.
The objective of the research was to determine how the addition of individual fibers, in different amounts, affects the mechanical properties of the renovation plaster.
These are the same places where the mechanical properties decreased.
All tested fibers improve the mechanical properties of porous renovation plasters.

Carbon nanotube (CNT) has been widely used as a kind of conductive inorganic filler in composites due to its excellent mechanical properties, thermal properties and electrical properties.
By testing the mechanical properties of prepared materials, they found that carbon nanotube could improve composites toughness.
The study reveals that the average conductive pathway density of CNTs (CNT alignment structure) mainly affect the anisotropy of electrical property.
Application in Biodegradable Plastics Biodegradable materials are environment friendly, but their popularization and application were restrained for high cost, narrow processing window, and poor mechanical properties.

It is a kind of non polar polymers, with mechanical properties and good elasticity.
Factors Affecting the Synthesis of High Styrene Rubber Temperature control: When the conversion rate was 98%, with the increase of the reaction temperature, reaction time is shortened obviously.
Styrene content: due to the quality of styrene and butadiene styrene rubber than the direct effects of high bound styrene content, thus affecting the physical and mechanical properties of products.
In addition, vulcanization system may have an effect on the blend properties.

By using this technique, different factors affected during rolling process can be investigated and controlled such as the metal flow, the distribution of stress and strain, and the deformation zone.
In consequence, the computational analysis with mathematical model by using Finite Volume Method had been applied to predict the suitable production process and good product quality, which base on the input of mechanical properties of raw material and process parameters [1].
Mathematical Model Modeling three dimensional models according to the rolling design, the assumption have been applied in the simulation for material properties such as mechanical properties and processing conditions as shown in Table 1.

According to the test results, the main factors influencing the bond behavior between mortars and blocks were analyzed, and the reasonable admixtures amounts were given.
Experimental Study The bond strength between mortars and blocks were affected by many factors.
With orthogonal test, the relationship of four factors: mortar grade, block type, PVB amount, MC amount and bond strength were mainly examined, and four levels of every factor.
The block type was the most important factor to affect the bond strength of specimens.
