Besides, the following assumption is put forth as the basis of the discussion: interstitial atom is just affected by those atoms which surround the interstitial atom and locate in the lattice.
In order to simplify the discussion, the analysis for force will be taken in one lattice and other factors except for Coulomb force will be neglected.
Generally speaking, the atom which locates in the gap position of lattice(be called interstitial atom) will be affected by lattice atoms which surround the interstitial atom at the same time.
As is well known that pure metal is made up of the stacking of lattice and temperature also plays a vital role in the performance of metal, so those factors should be taken into consideration in the future study to get more accurate results.

But most of previous work focused on the influencing factor of the vibration, such as traveling speed of vehicle, deck surface roughness and vehicle-bridge frequency ratio etc.
Bridge deck roughness is an important factor affecting the vehicle-bridge coupled vibration of highway bridges.
In engineering practice, the power spectral density(PSD) is usually used to describe the statistical properties of random bridge deck roughness.
Mechanical coupling relationship.

Bainite morphology and mechanical properties depend on austempering temperatures.
Austempering time is also an important factor which determines the percentage of bainite transformation completion and therefore can affect the final microstructure.
According to previous work by one of the authors [9], ferrite-bainite steels with 34% volume fraction of ferrite showed the optimum mechanical properties.
Mechanical properties of samples austempered at different temperatures are given in table 3.

They concluded that several factors do affect the maximum adsorption capacity and reaction kinetics such as the nature of the divalent and trivalent cations, their relative ratio, and the preparation method.
The equilibrium time is considered one of the important factors that affect the cost and applicability of the adsorption process.
Factors of the kinetic models for the adsorption of MO onto LDH.
Using different divalent cations with different ratios is one of the key factors affecting the properties and hence the performance of the resultant LDH nano-adsorbent.

Also allows the motor load starting as normal, mechanical overloading.
Electrical Equipment Failure Caused a Sudden Some Objective Factors The electrical heating equipment, high-current device electric power, electric contact points poor contact, arc these factors Heating of electrical equipment and electrical failures relationship From the energy point of view, is the root cause of the electrical equipment for heating the energy loss.
Poor electrical and electrical failure There are many reasons for poor electrical connection formed, the conductive material in the repair process or long-term wear, material properties change, the electrical contact performance deterioration of electrical contact form changes, resulting in increased contact resistance.
Environmental effects, temperature, high humidity, acids, bases, oxides, chlorine and other chemicals that affect accelerated chemical etching to increase the contact resistance.
In summary, rooted generate electrical fault circuit parameters change due to various factors, troubleshooting is based on the failure phenomenon using a variety of logic and experience accumulated gradually sort out, and ultimately to identify the point of failure, I hope this paper to find an electrical fault A little help.

Beside such methods as powder metallurgy, rapid cooling, mechanical alloying and other it is more frequently used manner of convenient obtaining of materials practically on each type of substrate.
In classic awareness the electrodeposition process of metallic materials on cathode is connected between other with the following factors: (i) nature of co-deposited metals and difference in their atomic radii, (ii) kind and state of the substrate structure, (iii) difference in equilibrium potentials of the deposited metals being the reason for overpolarization and depolarization of discharge of metal ions, (iv) rate of co-discharge process of the metal ions dependent on the electrolyte type, its temperature, pH and cathodic current density, and (v) interaction of the metal ions and another ions or solid particles existing in solution during the electrolytic process (underpotential phenomena, induced discharge, adsorption phenomena of the ions, chemical reactions of reduction and oxidation) [1-7].
Contemporary electrochemistry more frequently utilizes the electrodeposition process for production of new materials with concrete functional properties or materials being suitable for obtaining these properties after simple thermo-chemical treatments.
This results from the fact that technologies of the electrolytic production of composite materials possess many operating parameters enabling the controlled affecting on the structure of the obtained material and in consequence on their properties.
