The piezoelectric ceramics that suitable for transformer application should have a high mechanical quality factor (Qm) and low dielectric loss (tanδ) [4].
However, there is no single ceramic composition that owing such properties.
The electromechanical coupling factor (kp) and the mechanical quality factor (Qm) were determined by the resonance and anti-resonance technique on the basis of IEEE standards using an impedance analyzer (Hewlett Packard 4164 A).
While, the d33, kp and Qm factors are increased but went to saturation at approximately 6 mol% of MnO2.
The results show that the electrical properties can be improved via MnO2 addition.

Abstract: By means of mechanical properties test and structure observation, the relationship among electric field strength, polar molecule type, content on the Ni/TiO2 group electrorheological fluid properties have been analyzed.
It is found that with increasing electric field strength, the properties of electrorheological fluid increased for same composition ER fluid.
There are many factors affect the property and microstructure of ER fluid [4,5]., modified technique is one of most important factors affecting the ER property [6,7].
It has proved that polar molecule can greatly increase ER fluid properties.
This paper focuses on the research of properties and structure of Ni/TiO2 group electrorheological fluid modified with different polar molecule under different electric field.

However, the quantitative relationship between the solidification conditions and the resulting microstructures and mechanical properties has not been established since previous studies mainly focused on the multicomponent Mg-Gd based alloys under the unrestricted solidification condition and it was difficult to decouple the individual factors, such as cooling rate and composition, from the solidification conditions.
So far, there are limited studies on the microstructures and mechanical properties of Mg alloy under the restricted solidification, such as directional solidification technique [10-14], which is a powerful technique to investigate the effect of the individual factors (growth rate V, temperature gradient G and composition) on the resulting microstructures and mechanical properties.

The properties of WPC without coupling agent is close to that of products containing coupling agent.
The four selected factors for board fabrication were board density, hot-pressing temperature and time, and the amount of coupling agent, the three levels for each factor were shown in Table 1.
Property Evaluation According to China’s Industrial standard LY/T1613-2004 ‘Extruded Wood-Plastic Composites’[7], physical and mechanical properties of WPC boards, including density, moisture content, MOR, MOE, thickness swelling, internal bonding strength, water absorption rate of 24h, were tested and analysed.
the properties of WPC composites, the effect of hot-pressing temperature is greater than the density of composites, and the the amount of coupling agent had affected the performance slightly.

Analyzed the main factors of affecting hydraulic support stability, this paper analyses anti-topple and antiskid technology to apply to inclined angle 15~33°and compatible supports ZF4200/16/26.
Every roof situation in the direction of large inclined angle suffering different stress lead to different caving property, and the roof motivation can affect other supports strained condition and stability.
If the roof loses its initial property and the roof move downward, the support might topple.
Considering safety factor, we think that the support can topple if toppling angle is greater than 20°.
(3) Transport is another factor affecting support gliding.

In the conceptual design process, factors like the system, structure, spacing and tonnage of anchorage, and properties of rock and soil should be considered and measures should be taken to effectively control or reduce the effect of the anchorage force loss, which possesses great theoretical and practical significance on the design, construction , safety and social-economic benefits of the anchorage project.
The lock-in value of anchorage force in anchor rope is influenced by several factors such as material properties of prestress, mechanical properties of anchored medium, anchor structure, anchorage system, quality of anchor fixture, construction technology, environment of engineering geological, level of operation management and so on[1-2].
During the design process, several factors including materials of engineering geology, hydrogeology, meteorological data, bury content and obstacles, geologic terrain, surrounding environment of engineering and the significance of engineering should be considered.
