Therefore the suspended structure requires the sacrificial layer material with excellent high temperature resistance, low residual stress, good mechanical property, withstand large strains and satisfy the experiment conditions.
Because the graphic is very small, the process of each step will directly affect the final result.
The following are the basic steps of patterning the sacrificial layer: (1) pre-imidization (2) spin coating photoresist (3) prebake (4) exposure (5) developing (6) wet etching (7) hardbake (8) removing the photoresist Fig.1 Non-photosensitive polyimide graphical process 2.2 The influencing factors in the wet etching (1) Effect of surface cleaning on glass substrate in a wet etching Pinhole phenomenon probabaly occurs when the substrate is not clean.
While heating time too long and too short will cause the exposure of poor sensitivity, precision, and affect graphical effect.

Therefore, powder processing techniques have a vast potential to effectively reduce waste of material, secondary machining and finishing operations and to improve mechanical properties.
Microwave sintering provides fast heating rates, reduced sintering times, enhanced diffusion processes, reduced energy expenditure and improved mechanical properties [6].
All these factors are critical to the application of Sn-Ag-Cu alloys in soldering processes.
The effects of size and morphology of the intermetallic compounds in the mechanical properties is still a matter of debate.
Nonetheless, when their size is large and when in needle-like morphology, normally a degradation of the mechanical properties follows.

Paper-making tobacco sheet has advantages of low density of tobacco, high filling power, good mechanical properties and low tar, and the paper-making process is the main production technology for reconstituted tobacco [4,5,6].
Therefore, the papermaking processing technology play a key role in tobacco physical properties and smoking quality.
Fiber refining Tobacco stem were defibrillated to develop fiber properties with a rotating disc refiner (KRK continuous high-consistency refiner, No. 2500-Ⅱ, Japan).

Fiber self bonding and fiber strength are the most important factor affect tensile strength, fiber length is the most important factor influencing tear strength.Making reconstituted tobacco paper-base furnished with tobacco stem pulp and tobacco dust pulp, with decreasing of tobacco stem pulp percentage, content of long fiber in reconstituted tobacco paper-base was reduced, and tobacco dust pulp was difficult to combine with tobacco stem pulp, therefore, tensile index and tear index of reconstituted tobacco paper-base decreased considerably.

Thickness and temperature of SRM were two important factors influencing the permeation proportion of DMMP.
However, previous studies found that fumed silica mostly aggregated in the silicone rubber which influenced the mechanical property.
If P, Am, H, Fc are settled factors, the ratio of PI and Px was positive correlation to the permeability coefficient of the membrane (Pr).
Temperature of SRM was an important factor to permeability of SRM.
In conclusion, our results demonstrate that the PDMS/silica mixed matrix membrane with thickness not more than 10 μm possess desirable properties that can meet the essential requirement for sample inlet membranes of ion mobility spectrometers.

Based on different formulas and processes, it has good dielectric properties or excellent semiconductor properties.
Due to the peculiar material properties of the SrTiO3 substrate (High hardness, extremely uneven, high brittleness, and very thin), this leads to be easily destroyed (Rupture, scratch crack, pits) in case of the current machining process.
The pore not only has a serious impact on the accuracy and surface roughness of the final surface but also has a negative influence on physical properties, mechanical properties, using performance and subsequent electronic manufacturing process of the substrate.
So the compactness of sintered SrTiO3 is one of the key factors influencing its wide application.

The GMA is placed in a closed internal space relatively, and heat dissipation of the system will cause thermal deformation, having a great impact on the stretching the properties of the giant magnetostrictive materials and the implementation of the output precision seriously with magnetostrictive materials of nonlinear properties.
The choice of the temperature sensor and temperature controller system will directly affect temperature controlling accuracy and performance. 1.
If the temperature exceeds this range, the pulse width is full range; kp is a proportional factor; ki is the integral coefficient; kd is the differential coefficient.

The fuel properties are listed in table 2.
During the test, the injection pulse width of methanol was adjusted easily with calibration software on PC, and pilot diesel quantity was automatically controlled with the mechanical speed governor of the diesel engine.

As can be seen from Figure 2, it is evident that premixing methanol along with intake air of the engine dramatically affected the pilot diesel ignition delay period, in-cylinder pressure and PRR.
These factors resulted in decreasing NOx emissions.

The HTC depend on many factors, in relation to the state of the interface.
It is generally recognized that alloy temperature [1,2], formation of a shrinkage gap [3], chill temperature, surface roughness and chill material [4] all affect the heat transfer.
An explicit finite difference solution to the one-dimensional inverse heat calculation program [7, 8] was used based on a non-linear estimation method, which can be used to deal with the phase change and temperature-dependent thermal properties of solidification processes.
Anyway, a general increase in the whole cooling efficiency can be depicted without doubt, with interesting consequences for the design activity of sand casting processes and in order to obtain the best mechanical properties on the final product.
