It can be also seen from the experimental data, the ultimate strain of the shale reduced from 0.80% to 0.68% by the effect of water.
At the same time, the rock fissures water generates pore pressure, which reduces the compressive stress among the particles, even makes the ends of the rock fissures in tension state, thereby undermines the rock connection, leads to the reduction of cohesion and the friction coefficient of structural surface, and the physical and mechanical performance of rock is deteriorated. 3.2.2 Influence of freeze-thaw cycles on the mechanical properties of rock Table 1 shows that the strength of shale decreases with increasing of freeze-thaw cycles within the premier 20 freeze-thaw cycles, but its strength tends to be stabilized between the freeze-thaw cycles from 20 to 100 times.
While the enhancement of rock compaction property and the reduction of material capacity to resist deformation make the ultimate strain increasing constantly

At the same time, the PL intensity maxima showed samples with LiBr: S/2 and S/3 concentrations, which correlates with PL data in [3,4].
This corresponds to the maximum reduction in the sizes of silicon NC and confirms the lack of protection of porous silicon at low concentrations of LiBr.
This confirms the reduction in the oxidation of silicon crystallites in the PS layer after treatment and, therefore, provides protection for long-term storage.

The forward/backward spatial smoothing (FBSS) algorithm [9] can estimate DOA of coherent signals in multipath environment at the cost of reduction in array aperture, moreover, its required SNR is too high to put it into application.
The symmetric configuration of uniform linear array (ESCU) algorithms [10-12] can estimate DOAs of coherent signals at low SNR without array aperture reduction, but they are invalid in the presence of strong interference.
The received signals are converted down to intermediate frequency (IF), and data is used.

Increasing the technological parameters of devices causes a considerable wear of components and reduction of their lifetime [6,8,13].
Part of ISO 789-2 determines the test procedures to obtain the data about the lifting force of the rear THP: a) the maximum vertical force that can be generated during the hydraulic lift on the lower hitch points during the overall range of their movement; b) the maximum vertical force that can be generated during the hydraulic lift at point 610 mm rearwards from the hitch points, on the frame connected to the TPH, during the overall range of their movement; c) the optional ability of the lift system to hold the load in a raised position without using the hydraulic power input.

The size reduction or fragmentation of gold and silver nanoparticles induced by laser radiation has been observed [6].
To correct the interpretation of experimental results, the obtained data is crucial.

After taking out the electric furnace, the SS plate was hot-rolled (HRed) three times in a reduction of thickness from 25 mm to 12 mm, then plate was returned back to the electric furnace within a limited period that the temperature didn’t fall Table 1 Hot rolling condition of the 9CrODS steel HR number No.1 No.2 No.3   No.4 No.5 No.6 Thickness (mm) 25 to 20 20 to 16 16 to 12   12 to 9 9 to 6 6 to 4 Temperature 1 (ºC) 1100 to 947 947 to 1100 1100 to 862 below AC3Ts Tf Time Temperature Fig. 1 Shematic of the hot rolling and air-cooling of the 9CrODS steel point.
Subsequently, three times rot-rolling was repeated to reduce a thickness from 12 mm to 4 mm, corresponding to total reduction rate of 84 %.
The electron back scattering diffraction patterns (EBSD) was also conducted by using TSL data processing 4.5 software to evaluate a grain texture and crystalline orientation in an inverse pole figure (IPF) and orientation distribution function (ODF).

In supergene conditions, the high valence of iron manganese oxide can adsorbed molybdenum compounds and molybdenum be enriched, or in the reduction condition, hexavalent molybdenum reduced to tetravalent molybdenum, enriched in the sediments rich in organic matter and sulfur, the sediments containing rich iron manganese oxide, organic matter and phosphorus rich in molybdenum[3].
In the high oxidation condition molybdenum can be dissolved and carried, and in reduction condition will be enriched in sediments rich in organic matter and sulfur, this characteristics is similar with uranium, therefore, the sandstone type uranium deposits are often associated with molybdenum element, can form molybdenum geochemical halo.
Therefore, moderate intensity anomaly halos or abnormal high background can be used to indicate the volcanic rock type uranium mineralization by data processing.
