A differential form is required, as the resin undergoes important evolutions of its properties during the cure, that strongly affect the development of residual stresses.
In order to precisely describe those evolutions, the mechanical properties of the M61 resin were investigated.
This conversion degree is a state variable, and can be used for identifying the mechanical properties of the resin.
The gelation point is denoted by a marked gap of some properties.
The choice of a model or another mainly affects the out-of-plane properties, but also the in-plane stiffness; the EKSC model results in a more rigid material than the MTres model, but less rigid than the MTfib model.

Factors affecting the thermal conductivity performance magnesium alloy
ZHANG Shenghua[9] studied the effects of heat treatment system for Al-Mg-Si-RE-B tissue properties of the alloy.
Based on the above literature survey, the factors that affect the movement of electrons and phonons will affect the heat transfer properties of magnesium alloys, studies have shown that α-Mg alloy matrix elements in the solid solution heat conduction process will become scattered electrons and phonons Movement center, thereby reducing the mean free path of electrons and phonons movement, will directly lead alloy thermal conductivity and thermal diffusivity decreases.
This is the most important factor affecting magnesium alloy thermal conductivity and thermal diffusivity size.
Effect of RE on magnesium alloy’s thermal conductivity performance Magnesium alloy to give high priority based on their excellent mechanical properties and high temperature oxidation resistance, but less study of its thermal properties.

Furthermore, the factors affecting the UV transmittance is also analyzed in this article.
Introduction Because the synthetic quartz glass has the excellent properties of high light transmission, high optical uniformity, small thermal stress, strong radiation resistance and fine chemical stability [1], excellent [2], it is widely used in military and civilian optical system [3].
After high-temperature homogenization process, the shape of the quartz glass is more structured, the endoplasmic is more uniform, and the optical and mechanical properties are improved significantly.
It is found that the UV spectrum of quartz glass at the edge position has been affected after homogenization.

Finally, the alignment influencing factors can’t be determined.
The combined effects of the complex factors group formed the overall performance of the assembly body, the interaction between influencing factors and its contribution for the overall performance can’t be determined.
This paper attempts to establish the mapping relationship① through contact theory, exploring theoretical formula such as preload (), gap (), surface quality (), material properties () and stiffness (), damping () in order to establish agent model of various components.
Various parts contains only the quality attributes with no stiffness and damping properties.
A large number of agents with joint surface stiffness and damping properties are conducted computational experiment and communicated with the actual alignment system in real-time.

The advantage of orthogonal experiment is that the effects of each factor and their range on the
results can be differentiated when all the factors varying simultaneously.
The functional properties of tourmaline were not affected by modifying with TiO2.
In addition, the pigment properties were added compared with tourmaline.
Comparing the properties of TTCPM with that of tourmaline, the releasing negative ions quantity were the same, the whiteness increased remarkably, and the pigment properties such as hiding power, were added.
The excellent properties of TTCPM were proved by the paint tests.

This may be contributed by uneven distribution of pressure load, thus affecting the particles packing and properties of final product.
The addition of TiO2 and Cr2O3 hinder the grain growth of Al2O3 during sintering process, thus contribute to the improvement of ZTA’s mechanical properties [18,19].
The improvement in particles packing due to higher pressure influenced the mechanical properties.

At a fixed angle, slight differences in Hres among samples may stem from surface anisotropy factors such as smoothness.
These interactions alter the electronic structure and spin arrangement of the FeNi alloy, thereby affecting its magnetic properties.
Furthermore, interface effects may influence the damping factor and dynamic process of magnetization intensity, further modulating the film's magnetic properties[11,12].
Our findings reveal the mechanisms by which rare earth element doping affects the magnetic properties of FeNi alloy films and the complex behaviors exhibited during magnetization.

Welds were produced by employing rotational speed of 375rpm and a travel speed of 23.5mm/min.The microstructure and mechanical properties of friction stir welded joints were investigated.
Zhang et al. [2] examined the relationship between microstructure, mechanical properties and welding parameters in the Ti-6Al-4V FSW weld.
The mechanical properties of the as-welded joint was evaluvated by the tensile tests, and the specimens were cut by EDM from the same joint.
The cavities were observed at bottom of the weld, also another factor resulting in decreased mechanical properties.
The mechanical properties of the FSW joint would be improved when the process parameters were employed appropriate.

A great technological interest have developed in particle-filled polymer composites as improvements in properties of polymers can be done by reinforcing it with additional materials, so that overall properties of the composites are superior to those of the individual components as properties of the composite depends on the intrinsic properties of the reinforce material [1-4].
It possesses many remarkable properties, such as good thermal stability under operating and processing temperatures, inflammability, excellent resistance to chemical products in combination with very low creep and high mechanical strength.
As reference, neat PVDF samples were also similarly processed for study of the properties.
In general, the properties of semi-crystalline thermoplastic materials are strongly related to their internal microstructure and crystallinity, particularly the mechanical properties and thermal stability.
Due to the high rigidity of CaCO3 and the relatively strong interaction between CaCO3 and PVDF chains as well as the homogeneity of dispersion/distribution of CaCO3 into PVDF, the CaCO3 enhanced the mechanical properties of PVDF polymer.
