They showed that metastable thermodynamic nature and the particle surface topography are the major factors controlling the chemical performance of the metallic glass [9, 10].
The crystallization process is very important for the practical applications of amorphous materials, the properties of which are strongly affected by the crystallization process [14].
The detailed mechanical properties have been reported elsewhere [18].

As addressed in the section "Magnetic Carriers - Properties and In Vivo Fate," the size, charge, and surface chemistry of the magnetic particles are particularly important in affecting both blood circulation time as well as bioavailability of the particles within the body [12].
Certain key factors guide the choice of formulations and the technical details of the hyperthermia procedure.
The most important intrinsic factors are proton relaxation and the proton density of the tissue.
Besides, special care should be focused on the particle size, surface properties, magnetic properties, and administration route, for example.

Studies have shown that the occurrence of algal blooms are closely related with nutrients, temperature, light, and other organism’s factors[1].
Yamamoto et al.[2] discovered that algae blooms was affected by water flow in field investigation, Hosaka et al. [3] found that the appropriate shear rate could increase the growth rate of Chlorella, therefore, water flow was the important causing factor for the growth of algae.
Microcystis aeruginosa growth in autumn and early summer raw water were quite different at different flow rates, the biomass of Microcystis aeruginosa in autumn raw water was significantly higher than that in the early summer under fluid motion, it showed that autumn raw water was more conducive to the growth of Microcystis aeruginosa, TN and TP concentrations in raw water medium was similar, so this may be related to the medium properties.

Bubbles exist inevitably in natural water because of the flow, waves, mechanical agitation, change of pressure, biological photosynthesis and other reasons.
The main factors affect the diffusion velocity are the variety of gas, the solute concentration, the variety and proportion of surfactant, area of gas-liquid interface, and the physical condition such as temperature and flow disturbance, etc.
The initial radius r0 and number density ψ of IGN were set artificially to present different property of DEF.
However in this paper, the numerical calculation is limited to factors r0 and ψ.
Other factors in DEF expansion model will be analyzed in our future work.

Recent development trends, as urbanization, in combination with the occurrence of more and longer lasting weather extremes, are responsible for more frequent events with severe impacts on human lives and properties.
Two approaches for the determination of susceptibility maps are the most promising: (a) methods based on the statistical analysis of geo-environmental factors related to the occurrence of landslides; and (b) deterministic modelling based on simple mechanical laws that control slope instability.
Multivariate statistical models provide the best results for large areas especially at cases where the determining factors and landslide occurrence are complex.
I have personally accepted that the evolution of the Greek city-states resulted from the combination of the following three factors: i.
Many other factors, such as the size of groups of people, their level of education, the progress of their technology, outside forces, etc.”

Selection of an opening method depends on the relief shape and the surface situation, deposit’s reserves, physical and mechanical properties of rocks, deposit survey results, mineral reserves and their utility value, excavation volume, operation’s service life, deposit’s depth under the surface, and used mining methods [1].
Fn factors which determine the solution of the given problem.
Creation of the input table of the AHP method (Table 1) was preceded by the systematic analysis of factors (criteria) affecting the selection of the deposit opening method.
Analysis of the factors was carried out using the data from [11].

Its masonry materials have a good compressive property but bad tensile and flexural properties.
This bridge style gives full play to the advantages of its compressive property and makes up for the disadvantages of its tensile and flexural properties.
In terms of the mechanical behavior, girder and arch composite bridge is a typical ternary structure which is made up of the live load distribution member, the force transfer member and the main bearing member [1, 2].
Its arch feet are affected not only by the factors we said above but also affected by the three-dimensional effect.
