The properties of the seismic geophones are important factors for high-resolution seismic exploration and have a great infl uence on data quality.The traditional electromagnetic hydrophones in seismic exploration technology is relatively mature, mainly adopts the electromagnetic induction principle to design measuring speed vibration sensor[3-5].
Mechanical model is shown in Fig .2.
This is the principle of the electro-mechanical transformation by the acceleration piezoelectricity geophone.
They will not be affected by the natural frequency difference and excitation frequency changes, to increase exploration resolution and accuracy is significant.

Thermomechanical controlled processing is a very important way to control the microstructure and mechanical properties in low carbon, high strength steel.
However, bainitic ferrite is also a very critical factor for the mechanical properties of steel.
Both of these two factors commonly decided the mechanical properties of the steel, especially the toughness and hydrogen-related cracking(HIC).
The bainitic ferrite should be considered from its orientations and the packet size when it is used to evaluate the mechanical properties of steels.

Most of them have been come to the conclusion that those factors caused the crack initiation are surface decarboning, blocky carbides and longitudinal inclusions, the preventive method were also proposed to avoid similar events.
However, those factors have been improved with the development of industry, the Iron&Steel corporations in china have done great improvement on production of the raw materials.
Results and discussion The tensile test results shown in Table.1 reflect the mechanical properties of PC steel bars before and after cold-heading.

While its promotion is still very difficult, the major barrier affecting the application of green strategies is the high initial cost.
Xiaoling Zhang et al. [5] examined the benefits and barriers in applying green strategies in the process of housing development and facilities management, concluding that the major barrier affecting the application of green building was high costs.
What’s more, previous research focused on the factors affecting the cost and benefit while the evaluation and quantity indexes are not given.
But some factors that are difficult to quantify, such as the economic benefits of corporate image brought by adopting green strategies, are not taken into account, so further studies are needed.

Main factors can affect the quality of foaming board including Al/P (mole ratio of Al(OH)3 and H3PO4 ), M/P (mole ratio of all metal cation and phosphorous atoms) and content of carbonate.
According to these factors, orthogonal test was used to optimize the raw material ratio.
The orthogonal experiments were designed based on four factors and three levels, which choose 50g H3PO4(85%) as benchmark, Al(OH)3, MgO, ZnO and CaCO3 as influence factors.

On basis of the model, its epitomized model is formed to analyze the landslide mechanism and damage model by taking them into consideration: water-level fluctuation in reservoir, rainfall intensity, rainfall capacity and soil mass mechanical property, and decide current stability, predict its tendency and potential risks through applying the monitoring data and quantitative analysis.
The rock increase the water content with the rainwater, and at the same time increase the density, thus finally decrease the shear strength, all of the above factors result in landslide[1-3].
Boji stone landslide is in the northeast of Fulin region, and beside the Yangtze River, which belong to the denudation landform, and is affected by the Three Gorges Reservoir and rainfall, so this region has potential risk of landslide.
But the change of water level affects on the leading edge greatly, which are shown in Fig.7.
