Because of wide range of acoustic band for a variety of materials, AE also be called the stress wave emission and microseismic in geology[1].
Thus, AE technology can monitor initiation and expansion process of internal micro-fracture continuously, forecast the early or recent rupture of brittle materials caused by external load[6,7].
Many researchers try to establish the reliable experience relationship between AE and other properties of materials.
But rock is a natural material.

But the foaming med has strong corrosion, so the currently used tie material can not satisfy the requirement of duration.
So, it is emergent to create a kind of tie material, which is economic, antirust and has no pollution.
The process of making up material of reinforcement, making and curing of mortar and concrete specimen completed in test room.

Introduction There are two key techniques for transport of raw materials in the surface mining in Poland: continuous via belt conveyors and cyclic via heavy trucks.
The results can also be used as supplementary materials in the procedure for obtaining an environmental decision.

Conventional extraction of BFRs from polymeric materials is usually performed by Soxhlet extraction, which requires long extraction time and high solvent consumption [3].
Nevertheless, these advanced solvent extraction techniques means high energy cost and equipment requirement, which have become challenges faced by them to recycle BFRs from polymeric materials [15].
Experimental section Materials.
Standard stock solution of bromine ion (1000 mg/L) was purchased from the National Research Center for Certified Reference Materials of China and TBBPA (≥97% purity) was supplied by ACROS Ltd., and anhydrous sodium sulfate (Na2SO4) was analytical reagent from domestic manufacturers.

Predicting failure in composite materials is complicated due to the multiplicity of failure modes involving either fibres or the matrix or combinations of both [6].
Tsai Hill's criterion is based on the Von Mises distortional energy criterion which was modified by Hill so as to satisfy anisotropic materials and was subsequently applied to composite materials by Tsai.

This can be achieved by selecting the dimensions and materials so that their possible degradation does not affect the performance of the system.
To lower the warranty and repair costs for example, better materials and manufacturing processes which result in tighter tolerances, are usually needed increasing the production cost.
The design must provide sufficient torque without exceeding material compressive strengths.

In addition, in order to reduce the heat loss and improve the efficiency of system, the heat storage layer is covered with insulation materials.
The canopy material is usually transparent glass and the material of chimney wall is concrete.
The material physical parameters are shown in Table 1.
