Introduction Plasma-assisted surface modification is an important material process for modifying material surface properties [1-5].
The velocity of ions and the kinetic energy are affected because of the strong magnetic field between the anode and the substrate.
Furthermore, the uneven distribution of the magnetic field around the sample surface reduces the distribution uniformity of the ions sputtering on the sample surface, which could affect the uniformity of the conical protrusions on the sample surface.
Conclusions For SUS304 stainless steel, the sputtering power, the anode-to-substrate distance, the argon gas flow ratio and the sputter-etching time were important factors in protrusion precipitation on the steel surface.

Identification of eddy dynamometer in vehicle emission test based on SMI method Ping Liu 1, a 1 School of Mechanical Engineering, Southwest Jiaotong University, Chengdu 610031, China a univerlp@126.com Keywords: vehicle emission test ,subspace model identification , eddy dynamometer.
To solve the parameter estimation problem ,many parameter estimation algorithms are based on mathematical optimization These identification algorithms not only require the user to select a specific set of model parameters, but also require the user to accurately select the initial value, these two choices play a critical influence on the optimization results, then affecting the quality of the identification model.as an effective way to identify the multi-input multi-output system.the subspace model identification (SMI) method has gained wide attention in recent years[1,3].This method is superior than the traditional method in complex high-order systems[4].
Multi-level test of the two factors is carried out, and the torque output of each test was recorded.
When model is built by identification method, the object properties should be considered.

a) Protect the FBG from abominable construction conditions; b) Reliable bond with the asphalt; c) Simple structure and easy to process; d) Packaging structure and size is reasonable; e) Without destroying and affecting the state and distribution of the structure stress after embedded in asphalt concrete.
With comprehensively considered the above factors, a FBG sensor with simple packaged form is designed .Generally the average strain of the distance of triple largest aggregate is taken as the strain of asphalt concrete, so the length of the sensor is set at 130mm.
(1) According to the characteristics of asphalt concrete structure and the properties of construction, a fiber Bragg grating sensor is designed to monitor the dynamic response of asphalt concrete.
(3) The simulated impact test concluded that the sensor can timely respond to the instantaneous impact loading, at the same time the mechanical performance is favorable, and the sensor can meet the requirements of monitoring the dynamic response of asphalt concrete pavement.

It will affect the mechanical properties of the composite transmission and cause stress concentration.
After the material is heated, the internal structure of the material will affect the transmission and impact of material changes in the temperature field heat waves.

This elevated porosity will affect the transport properties of concrete [1-3].
The ITZ is a weakness zone in the microstructure of concrete, but it is one of the most important factors influencing the performance of concrete.
Firstly, the sections of concrete specimens can be obtained by mechanical cutting, grinding or splitting, and the digital images of the sections are recorded in a vertical angle by a digital camera.
But the nonsmooth section would not have affected the digital image analysis.

Relations between these factors and unique specifics of offshore type vessels have been pointed out.
The choice of a particular ship power plant is influenced by such factors as: ship electrical energy requirements, specific properties of groups of energy receivers, power plant mass and size aspects and also, treated as very important, the issues of reliability and economy.
Design factors determining the architecture of offshore type vessel power plants Electrical energy requirement depends on the size, destination and specifics of the vessel.
A failure occurring in one of the plants does not affect the operation of the other and thus a high reliability of the system is obtained.
A diagram of a supply vessel (PSV) power plant The power and the layout of the ship power plant as a sum of the installed power in energy source/generating unit modules as well as their types are determined for a defined number and properties of electrical energy receivers in the most important ship operational states.

Introduction Duplex structure or heterogeneous structure material has been becoming the hot research topic because of its excellent mechanical properties [1-5].
The results proved that the ultrafine grain size and large fraction of austenite could contribute to the significantly enhanced mechanical properties.

A cermet is ideally designed to have the optimal properties of both a ceramic, such as high temperature resistance and hardness, and those of a metal, such as the ability to undergo plastic deformation.
Corrosion is the physicochemical interaction between a metal and its environment that results in changes in the properties of the metal, and which may lead to significant impairment of the function of the metal, the environment, or the technical system, of which these form a part.
This makes it necessary to study the effects of the ions in the solution on the corrosion phenomenon, with due consideration to such factors as the type of metal and anions.
The corrosion behaviour of cermet alloys should be affected by the corrosion behaviour of its components, the galvanic effect of the WC-Co couple and the galvanic effect between the matrix regions of higher W concentration.
Cyclic polarisation of WC-Co in seawater Anions as well as the structure of the surface, affect the anodic current-density potential curves in oxide-free dissolution, as in acid solutions.
