Based on the analysis to the factor influencing the cost of heat medium transportation system, the mathematical model to optimize the heat medium transportation velocity is constructed.
Introduction The value of the heat medium transportation velocity not only affects the heat loss of the heat pipe surface and the mechanical transportation energy consumption, but also affects the initial investment of pipeline system.
In the process of design, the heat medium velocity will directly affect the total loss cost of the heat medium transportation system.

This paper based on the in-situ data of "7.16 coal bump accident" of Chengshan coal mine, by summing up and analysis, determine three factors:the time, the gob and the nature of the top which may affect the energy accumulation,and simulating the influence of the energy accumulation the above three factors bring through Flac3D, according to the different level of influence of various factors on the energy distribution, obtaining the main control factors of energy distribution of coal bump.
(3)Through make the roof nature abated, research roof properties effects on energy distribution, and named it scheme 5.
In a word, each factor’s influence degree to energy distribution from big to small is: goaf, roof’s properties, time and the most effective influence is existing goaf in roof. 3.Conclusions The influence of time, goaf, roof’s properties on energy distribution law is simulated through different comparison method.
Get the conclusion: the above three factors can affect the elastic energy distribution nearby the working face
Therefore, the influencing extent from big to small is: goaf, roof’s properties and time.

The selected compositions (table 1) were investigated for physical and mechanical properties (table 2).
Physico-mechanical properties of polymer-bitumen composition.
The resulting series of samples of asphalt concrete were studied for physical and mechanical properties, the results are shown in Fig. 2.
Physico-mechanical properties of stone mastic asphalt concrete.
Summary The results showed that the use of “warm” chemical additives in the PBM composition in the production of crushed stone and mastic asphalt concrete, due to its mechanism of action, ensures the process ability of the mixture at lower compaction temperatures, without negatively affecting the properties of the final product - asphalt concrete.

It discusses the main influencing factors of the piezoresistive effect.
Its conductivity has relationship with rubber matrix, filler type, filler content, temperature and the other factors [1,2].
But it has an adverse effect on the mechanical properties.
Thus it affects the mechanical properties.
A large amount of the filler will affect its dispersibility, so that the plastic material hardens, becomes poor releasability and reduce the plastic of processing properties and mechanical properties of the material.

In this paper, the compressive strength of combined aggregate concrete is studied, and the factors affecting the strength: the replacement ratio of lightweight aggregate and the water-cement ratio are discussed, and the formula of combined concrete strength is given.
The influencing factors : the replacement ratio of lightweight aggregate(0, 20%, 40%, 60%, 80%, 100%), water-cement ratio(0.3, 0.35, 0.40, 0.45) is considered.
Coarse aggregate strength is the main factors influencing the strength of concrete.

Experimental Investigation of Mechanical Properties and Effect of Porosity on Epoxy Granite Composite S.
Regression analysis was applied to establish the empirical relation between inherent properties and mechanical properties.
The mechanical properties was examined on concrete porous and found that it is extensively influenced by the internal formation of porosity.
Factors Influencing Epoxy Granite Composites Main factors which influence the epoxy granite and their levels are decided based on the literature and the two factors fixed for this research work are composition by weight% and aggregate size are 70:30, 80:20 and 90:10 for aggregate sizes of T1, T3 and T4 specimens.

Tensile properties and fracture toughness of coconut spathe fibre for untreated and treated were evaluated.
It showed good improvement on mechanical properties.
Results and Discussion Tensile Properties.
This suggests that the chemical treatment might not affect the fracture toughness as opposed to the tensile properties.
The result indicates the alkaline treatment is harmful while the silane treatments are possibly the alternative treatment in improving mechanical properties on coconut spathe composites.

The research on the rebar corrosion and its effect on the mechanical properties of rebar is increasing [8-10].
The samples (Φ14mm ×450mm) are used for corrosion rate measure and mechanical properties tests.
The tensile mechanical properties, including yield strength, tensile strength and elongation, are tested by a hydraulic pressure universal testing machine.
And then the corrosion rate calculation and mechanical properties tests are carried out.
These will affect the strength properties of rebar.
