The influences of phenolic resin content, forming pressure, sintering temperature of samples on the performance of green body, mechanical microstructure and properties of RBSC were studied.
As well as we known, the existence of residual silicon in RBSC would restrain the working temperature and reduce the mechanical properties of RBSC[11], which is unavoidable due to the RBSC process of infiltrating molten silicon into carbonaceous green body under capillary action.
Therefore, the characteristics (such as mass ratio of raw materials, density, porosity, pore-size, etc.,) of green body decided by green body preparing is one of the most important factor to affect the residual silicon content and the properties of RBSC.
The effects of green body forming process parameters on microstructure and properties of RBSC had been investigated.

Fig. 1 Service of cloud-based mass customization service platform Parallel processing of product configuration There are many cloud-based product configuration problems to be solved: (1) Because the relatively large correlation between product configuration data in computing process, The overall performance would be affected by so large amounts of data transfer between nodes; (2) How to ensure data transmission security between the data nodes; (3) The parallel split of MAP is affected by the strong correlation between the configuration data.
In addition, associated types also can be defined by establishing the associated objects between brother PFSCs and assembly properties between instance objects of the brother PFSCs can be expressed by use of the adjacency matrix representation.
So we should consider a variety of factors which affect the effect of the service in the cloud-based mass customization service platform and comprehensive application of the factors and parallel processing so that we can more effectively improve the speed and response of services in the cloud-based mass customization service platform.

The primary component of plantation fir was analyzed, fir scrap properties were tested in contrast to peeled fir.
Single-factor experiments were employed to discuss the influential factors liquefying plantation fir scrap by ionic liquids.
The ionic liquid is prepared according to previous literature[10]. 1- butyl-imidazole and 3-chloropropene were added in a three-mouth flask with mechanical agitation, the reaction was operated under the protection of nitrogen at 60 °C for 24 h, the intermediate, [BAIM][Cl] was synthesized after washing and drying.
In a 500mL three-mouth flask with mechanical agitation and spherical condenser tube, dried 60 mesh or so wood-flour and liquefaction agent [BAIM][Cl/AlCl3] were added according to a certain proportion(mass ratio of ionic liquid/wood-flour) , and then refluxed in an oil bath under the protection of nitrogen at schedule temperature, observed the phenomenon of reaction, when reached the scheduled time, stopped heating and stirring immediately.
In the first stage, liquid/wood ratio increased from 5 to 7, residue rates decreased rapidly, which affected significantly by liquid/wood ratio, it was favorable to increase liquid/wood ratio.

The development of composite asymmetric membrane is a major breakthrough in membrane research field, as this membrane offers significantly high selectivity without affecting the mechanical durability of the membranes.
Depending on these factors, the effective strategies should be selected to control the fouling [27].
Furthermore, mechanical properties and durability of cellulose composite membrane are maintained by incorporating different additives such as nanoparticles [61], carbon nano tubes (NTs) [62] and silica [63].
The benefit of using composite membranes is that by tuning the thickness of both hydrophobic and hydrophilic layer, parameters such as mass transfer rate, heat transfer rate and mechanical properties can be controlled.
The key advantage with the thin film composite membranes is its high selectivity without compromising the mechanical properties of the membranes.

Electrochemical micromachining can machine hard to cut materials irrespective of their physical and mechanical properties and the material should be electrically conductive.
Machined surface is stress free and burr free and the heat affected zone (HAZ) is reduced.
The rate of anodic dissolution or machining depends upon its atomic weight, valence, the current density and the time of machining and is not affected by the hardness and mechanical properties of the materials [4].
Therefore, the four input factors has been chosen with three levels in this present work.
Step 4: Calculate the grey relational grade Step 5: To select the maximum average grey relational grade for input factors [11].

But test results always are affected by various interference factors and we gain not good control precision in the operation process of actual computer control system.
The top two classes is uncertain environmental factors or external disturbance, the third belongs to uncertain model factors or internal disturbances.
The preparation value of v(k) and n(k) in sampling time is unknown, but their statistical properties can be obtained by observing the data.
Here we assume that they are all weak stationary random process, namely their statistical properties is certain.
Theoretically stationary random sequence v(k) can be generated by white noise sequence w(k) through a forming filter, so that stationary random interference affecting control system can be equivalent to interference of white noise acting on system by forming filter, which brings great convenience to analyze and realize control system under random interference.

The degradation of wood in outdoor conditions is mainly a surface process and it is caused by factors such as solar radiation, moisture, temperature, dust and other physical and biological agents [1, 3] as a result primarily color changes and mechanical damages occur.
Investigation of changes in wood during weathering is important for finding of new more efficient treatment solutions that ensure the required stability of the decorative properties.
In this study the artificial weathering test was carried out to evaluate and select the processing parameters which could enhance the service properties of the final product.
The only parameters which can affect the absorbed amount of paint are, at a fixed temperature, the dipping time, the viscosity and the composition of the paint and the morphological properties of the wood surface.
