According to the experimental results and existing data processing experience, We could safely predict the existence of this curve, and the force and the shape of the sample did not affect the existence of this article curve within a certain range.
Taking all these factors, the test error is about ± (6% ~ 7%).

The most important factors that have a profound influence on the toughness are strain rate (loading rate), temperature, notch effect.

Then, the resulted films were characterized on their optical, structural, and photovoltaic properties.
Therefore, in the detailed study, we investigated the effect of those layers on the optical, structural, and photovoltaic properties of BiOI films.
Due to the covalent bond in all atoms, BiOI has good optical and mechanical properties.
We assumed that the insertion of TiOx and TiO2 might affect the shunt resistance value (Rsh) and it had an impact on the open-circuit voltage enhancement.

There are numerous factors that have an influence on the accumulation process including temperature or a loading program [4].
Mutual interactions of strains and stresses being accounted in the energy based approach description make it difficult to define unequivocally cyclic properties of steel P91 on the basis of the process of strain energy changes.
Conclusions On the basis of plastic strain energy ΔWpl analysis, in the function of the number of loading cycles, can be said that P91 steel is characterized by changes in cyclic properties.
It is difficult to identify the cyclic properties of the investigated steel on the basis of unequivocally energy change ΔWpl.

Introduction For over a decade carbon nanotubes (CNTs) have been the source of abundant theoretical and experimental research due to their extraordinary mechanical, electrical and optical properties [1].
Since the properties of CNTs vary depending on their structure, synthesis method development has targeted selective formation of CNTs with controlled diameter, length and chirality, as well as the number of concentric graphite walls.
This work aims to promote the understanding of the basic mechanisms of CNTs formation in the CVD by investigating the conditions for CNT growth, the factors affecting CNTs length, and the sizes and types of catalyst particles, which subsequently determine the formation the CNTs.

The prepared geopolymers were cured at different temperatures (ambient, 40 ℃ and 60 ℃) and were studied to determine their strength, bond structure, mechanical properties, and resistance in an acidic and salty environment using an accelerated durability test.
Its composition (Na2O / SiO2) and physical property, especially the viscosity, has a major effect on the final properties of the geopolymer [13,25].

However, the poor mechanical properties of HA with regards to its brittleness and low fracture toughness restrict its use in load bearing application [1-2].There were several approaches for the improvement in mechanical properties of the HA.
A well-known method of improving the mechanical properties of HA specimens was based on the synthesis of composites made of HA and other reinforcing phases.
Bioinert ceramic oxides like alumina (Al2O3) and zirconia (ZrO2) having high strength was used to enhance the densification and the mechanical properties of bioceramic[3].
It was reported that HA and titanium composites showed significantly higher mechanical property [4].
The porosity, α-TCP and β-TCP contents affect the dissolution behaviour, strength and biological properties.

The connotation essential factors constitute sports building system's skeleton, the extended conditions enrich the sports building system's compatibility, enable its comfortable existence, the two complement and actuate mutually.
Structure boundary conditions refer not only to beams, columns and other physical border, but the environment, geographical and societal factors which affect the building structure should be integrated into the boundary elements.
To carbon mitigation, structure matching should comply with the following principles: (1)Preference for lightweight and efficient tensegrity structures, such as looped cable roof, cable dome, suspen-dome etc, to avoid the whole structure system loss of seismic capacity or carrying capacity caused by some elements destruction, in order to take full advantage of the mechanical properties, to achieve its ecological significance of carbon mitigation.
