At the same time, the fountain solution is removed, resulting in the temperature of the ink in the printing process is too high and the ink stickiness is increased, then affecting the printing quality.
(4)The temperature of the blanket cylinder does not affect the deformation of the blanket.
Conclusion Temperature is an important issue to affect the normal working of the waterless press.
Before calculating the heat transfer of the cooling roller, need to analyze the heat transfer model and the influence factors, and build an ideal physical model, then analyze each module of the model and calculate the theory formula.

Therefore, identifying the nature of bonding force between C-S-H clusters becomes the striking point to understand the cementing properties of the cement pastes.
With appearing the atomic force microscopy (AFM), the properties and characterization of bonding forces between C-S-H clusters in concrete have become the focus of the research recently.
AFM becomes a popular tool in studying the three-dimensional structural characteristics of materials, meanwhile nanoscale mechanical properties of the sample surface by means of force-distance curve [4].
Therefore, it would be applied to reflect indirectly the nanoscale mechanical properties of the cement-based materials.
Through analyzing the main influencing factors, the validity of bonding force results is assured, which lay the foundation for simplifying the method of the measuring force values.

The prestressing force is the significant factor that influence the strengthening of steel H-beams.
In addition, steel structures are only marginally affected by friction loss when steel tendons are applied.
Fabrication and mechanical properties of internally prestressed steel I beam produced by combining steel T profile and prestressing steel plate were investigated, it was observed that flexural strength of prestressed steel I beam produced by this method has increased by about 30% [4].
The properties of the materials that were used are given in Table 1.
Furthermore, the amount of prestressing force applied is the significant factor that influences the strengthening of steel H-beams.

The effects of the length and the content of PPF as well as the content of AEA on the physical properties (dry density, drying shrinkage) and mechanical properties (compressive strength, flexural strength) were investigated.
Table 1 to 3 show the chemical compositions of Portland cement, the mechanical properties of PPF and the mix proportions of FC, respectively.
The stability of foam can be affected by many factors such as temperature, humidity, atmospheric pressure and air movement.
Fig.3 shows the effects of PPF length and content on the mechanical properties (compressive strength and flexural strength) of FC.
Despite these benefits, it must be noticed that the action of PPF to compensate shrinkage is limited by the mechanical properties of itself.

The following factors are considered in the analysis: (1) the restraint due to geometrical features in the metal die; and (2) process parameters such as dwell time, die/platen temperature, injection pressure, and injection temperature.
Introduction Metal matrix composites have received much research interests over several years due to their excellent mechanical and thermal properties compared with the conventional materials.
By suitable arrangement of metal matrix and ceramic addition, it is possible to obtain desired properties for a particular application.

The aims were to analyze the influence factors and the interaction of these parameters with respect to surface quality produced.
Trimming of composites is different from that of common metal cutting in many aspects, because the composites itself not only inhomogeneous but also dependent on fiber orientation and mechanical properties.
Moreover, P-Value less than 0.05 indicate the factors are significant.
