Abstract.
In case of strong texture the conventional sin 2� technique can hardly be applied since, with exception of high symmetry materials (cubic), different reflections appear for different inclinations of the diffraction vector.

In construction process, device of preventing water inrush is installed on the grouting orifice tube to prevent accidents.
2.3 Water prospecting
According to the geological characters of mine, applicable conditions of mine direct current electric method, mine transient electromagnetic method, radio wave penetration method and other Water prospecting method, transient electromagnetic method is adopted to prospect water during building the slope.
2.3.1 The mine transient electromagnetic method
Transient electromagnetic method is known as time domain electromagnetic method, also known as "pure anomaly field method", use loop source to send a underground electromagnetic field, in an electromagnetic field intermittent period, use the coil to observe the secondary eddying electromagnetic field produced by the underground abnormal material, so predict the distribution of underground mining, geological structure, aquifer based on the research of the characteristics of the secondary eddying
However, mine transient electromagnetic method compared with the ground transient electromagnetic method has the characteristics of the following aspects: 1) Due to underground measuring environment is different from the surface, could not have big coil used on the surface, can only use a great number of turns of small coil those length is less than 3 m, labor intensity of data acquisition is small, measuring equipment is portable, efficiency of operations is high and cost is low. 2) Due to measuring by small coil, distance is mine dense (generally of 2~10 m), reduce the influence of volume effect, and improve the resolution of prospecting especially the lateral resolution. 3) Due to the effect of cut-off time, can not prospect mine shallow abnormal material (shallow within 15 m).

Abstract.
Materials and Methods Chemicals. perfluorooctanoic acid (PFOA, 90%) were purchased from Fluka (Milwaukee, WI).
As the impact to the defluorination rate, both anions and cations can inhibit the defluorination process, but anions have much greater impact than the cations to the defluorination rate. b Acknowledgement This study has been supported by the National Science Foundation Committee of PR China (Project No. 20807032, 21177094, 41271465).
