Secondly, for properties of longer response time, overshoot, and difficulties in establishing precise mathematical model of the pneumatic control system, this paper uses fuzzy PID control method to control the pneumatic output pressure.
Combination of both to control the output pressure not only can make the pressure values achieve pre-test value as quickly as possible, but also can control the pressure in appropriate context and not affect the normal work of instrument.

Protein hydrolysates have properties that make them attractive as a source of protein in human nutrition.
However, some factors such as slow and incomplete hydrolysis, hydrolysate with bitter taste, low yield of the desired hydrolysates, difficulty for hydrolysate separation, exist during hydrolysis.
These are limitting factors of restricting the development of hydrolysis industry of food proteins.

Furthermore, adhesion of film to substrate is one of the most important factors.
Since silver or silver ion has strongly bacterial inhibition property, there are plenty of researches studying on this property over few decades [15-17].
The last treatment, SiC paper grinding, is mechanical interfacial layer type forming on rough or porous substrates [10].
The area affected is 5-15% of the grid. 2B : the coating has flaked along the edges and on parts of the squares.
The area affected is 35-65% of the grid. 0B : flaking and detachment was worse than 1B.

The C/S molar ratio and activated carbon circulating ratio were important parameters affecting SO2 removal efficiency [6].
The reaction temperature affects not only SO2 adsorption onto activated carbon, but also SO2 catalytic oxidation into H2SO4 [7].
The reaction temperature has more of an effect on physical adsorption, and therefore SO2 adsorption capacity decreases with increasing temperature, which then affects the SO2 catalytic oxidation.

However, the resulting surfaces are not uniform because the deposition rate is not constant as it is affected by electric field that is applied on surface of the microstructures [16].
From the results of simulation, the variation of gap was the main reason affecting the electro field strength on the surface of microstructure.
In order to fabricate complex-shaped 2D and 3D microstructures, the factor for control the geometry of microstructure should be analyzed.
The top point of microstructure determined by the algorithm used in this research can be used in all experiments with reliability and reproducibility, and it has clearly definition on geometry even though this point has no chemical and physical properties.
Microstructure angle relative to microstructure position (E–H). 4.3 discuss with simulation According to the previous study [4] and the theory of electrochemical, electro field strength is the most important factor to affect deposition rate.

Therefore, the friction factor m at the die-workpiece interface for the simulation is assumed to be 0.05 ~ 0.15 [9].
Note that other design parameters such as punch angle (2α) and friction factor (m) are set to be 170° and 0.1, respectively, to see the apparent effect of outer diameter ratio on the force requirement.
It is noted that the other process parameters such as the friction factor, punch angle, punch corner radius and die corner radius have constant during the whole extrusion process.
(d) The friction factor and punch angle does not affect very much the load-stroke relationships and volume ratios.

The protective performance of the Zn coatings has been improved with the use of cyanide baths which is highly toxic; though other factors influence the quality of Zn deposition (plating bath composition, nature of substrate surface and plating time) [15, 16].
The theoretical significance factor is the standard value wherewith the mean square ration must be greater than for the statistical relevance factor to be established.

Aiming to go deeply into this aspect, in this work the occurrence of IMTs and their properties have been examined for an extensive set of off-stoichiometric Ni2MnGa.

Although the Curie temperatures determined by this method are affected by a considerable uncertainty, they are reliable enough to account for relative changes in the position of the magnetic transition.
Similarly, neither the quench temperature nor ageing after quench affect significantly the Curie temperature TC.
To find, if any, a systematic relationship between the composition of Ni-Mn-Ga and the occurrence and properties of intermartensitic transformations, the available data has been plotted as a function of the electron to atom ratio (e/a).
