In recent decades, decreasing metal ore grades and the complication of the mineral composition of ores have been observed due to the depletion of high-grade raw materials, and therefore low grade ores and mining wastes are considered as the most promising sources of different metals [7, 8].
Materials and Methods  The object of the study was a sample of uranium ore from the Vostok deposit (Northern Kazakhstan), which was subjected to long-term acid leaching.

Experimental Design Materials.
In the testing of soft materials, because of the low strength of soft materials, the transmission stress is small; the semiconductor strain gauge becomes the most effective method to test weak signals.

The harm of train fire is conducted in heat radiation, harmful smoke flow and oxygen loss, and the new synthetic materials make poison gas suffocation as the death factors in the fire cause injury.
While other combustible materials, such as the seat, participating in post-combustion shown in fig.4 (d), the smoke flow velocity is increased and the fire is rapidly developed.

Another possible explanation is that increasing the accumulation of fresh litter and partially decomposed organic materials keeps precipitation from permeating to the mineral soil.
