This study investigated the chip dispersal behavior during the drilling of CFRP to identify the factors that affect the dispersal of cutting chips.
This study was based on observing the behavior of cutting-chip dispersal during the drilling of CFRP with a view to identify the factors that affect the dispersal of cutting chips.
Table 2 lists the mechanical properties of CFRP.
These results suggest that the scattering of cutting chips is not affected by the airflow field around the drill edge but by other factors.
The scattering of cutting chips is attributed to factors other than the chip size and discharge speed.

The results showed that adding some nano-ZnO powder in paint did not affect the mechanical properties of the coatings, but it influenced obviously the surface topography and characteristics.
Some research has demonstrated that many other factors are of equal or greater importance than the surface energy.
These properties can meet to the general need of antifouling paints.
Based on the above-mentioned results, it can be obtained that adding some nano-ZnO powder in paint did not affect the mechanical properties of the coatings, but it influenced obviously the surface topography and characteristics.
Adding nano-ZnO powder in paint did not affect the mechanical properties of the coatings, but it is easy to get hierarchical porous rough surfaces.

Based on Bishop Model, the equilibrium equation is established to evaluate the slope instability risk accounting for the uncertainties arising from soil properties and water level.
It is difficult to reflect the stochastic influences by using deterministic approaches because uncertain factors always are stochastic.
Uncertainties in soil properties can rise from inhere spatial variability in the properties and random testing errors in their measurements.
Geotechnical properties of slope is shown in Tab.1.
Directly searching method for slip plane and its influential factors based on critical state of slope.

Introduction Thermoplastic materials, especially those of the polyethylene (PE) type, have become in recent years the most used for the construction of pipeline systems for the circulation of natural gas, due to their many properties that are important advantages compared to metal, such as: lower density, high chemical and corrosion resistance, easy and fast welding possibilities, relatively low assembly and maintenance costs.
The optimization methodology is a set of mathematical and statistical techniques that are used to establish a relationship between objective functions and controllable factors.
The influences of two of the controllable factors on an objective function can be presented in the form of three-dimensional graphs on surfaces.
Table 2 shows the optimal values of the controllable factors that satisfy the requirements imposed on the objective functions.

Curing temperature and air humidity are among the prominent external factors that contribute to the alteration of geopolymer properties.
These solutions were prepared 1 hour prior to the mixing process to prevent the excessive heat generated by sodium hydroxide dissolution from affecting the measurement of fresh geopolymer paste properties.
Analysis on the result of fresh properties test (setting time, workability) and hardened properties test (density, compressive strength, porosity and elemental composition) exhibit various correlations that justify the effect of polymerization of geopolymer precursors to the geopolymer properties.

HAp ceramics have attracted the interest because their bioactive and biocompatible properties.
Tenhuisen et al [4] and Durucan et al [5] investigated the factors influencing the kinetics of calcium deficient hydroxyapatite, CDHAp, which formed from the hydrolysis of α-TCP in an aqueous system.
The preparation and the mechanical properties of α-tricalcium phosphate/gelatin gel composite have been studied by a number of authors but HAp formation was sluggish.
The molecular weight of gelatin had no effect on the rate of HAp formation, it may, however, influence mechanical properties.
Collagen processing is the key factor affecting HAp formation.

The factors affecting the fatigue life of asphalt concrete are divided into internal as well as external factors.
Internal factors include asphalt typesamountgradation and porosity[4]while external factors include load axle weightintermittent time and temperature[5].

It was found that microstructural differences between surface and bulk of the samples affect their thermoelectric properties.
The final microstructure of ceramic materials depends on various factors such as properties of raw materials, sintering conditions as well as the shaping method used.
The shaping method can significantly affect development of microstructure during the sintering and hence the final properties of the sintered bodies [3].
It was found that these microstructural differences between the surface and bulk of the samples affect their thermoelectric properties.

Wood as a natural resource is subject to continuous degradation by means of different environmental agents, where fungal decay is one of the main factors affecting timber structure elements.
Introduction Wood is one of the oldest engineering materials; however, mechanical properties are strongly affected by its organic nature and its vulnerability to biotic agents.
In a consequence of such degradation significant changes within physical, mechanical and chemical properties occur.
In wood infested with brown-rot strength loss occurs faster than weight loss, which leads to greater effects on decreasing of mechanical properties (MOE, MOR) [2].
Wood used in historical constructions is more or less modified due to various and complex degradation factors, in many cases even not known for the researcher.

The die material is one of critical factors for isothermal forging.
Effect of Hf, Zr, Ta, Nb on the tensile properties of DM02 alloy at 1050rC.
The tensile properties of the four specimens at 1050°C are shown in Table 3.
As above-mentioned, large primary M6C is detrimental to mechanical properties of the alloy, especially to ductility.
Therefore, 2# specimen would have good comprehensive properties.
