Introduction Primary defects generally exist in solid materials such as rock.
Under the action of external stress, the interiors of the solid materials may be damaged and failed caused by the possible activated internal defects.
During the fracturing and damaging process, the solid materials release strain energy and the energy propagates rapidly by means of elastic wave.
Acoustic emission character of rock materials failure during various stress states [J].
The spectrum analysis of acoustic emission signal in rock materials [J]. 

The Test of Squat Silo Unloading Pressure Test Model and Stored Material.
The transducer’s out skin is made from aluminium materials, it’s double film midsize of soil pressure gauge, the soil pressure effected on the first film deliver pressure to deformation membrane through the vacuum fluid which greatly improve the degree of measurement and has a good adaptability to the different properties and the diameter of the particle medium.

Introduction Mineralogical materials, which are used in cement, mortar and concrete to increase their binder and some physical properties of them, differ from inert materials such as filler etc.
Mineralogical materials were also used in cement manufacturing in India as raw material.
However, mineralogical materials were mixed concrete as aggregate in South Africa in the past.
In other countries added mineralogical materials both cement and concrete.
To add mineralogical materials to cement, mortar or concrete up to 40% causes over 40% reduces on compressive strength of cement in initial days, for example 7-day, because of mineralogical materials content.

Pure aluminum thin film is introduced in the designed structure, which consists of mainly organic polymeric materials, to improve the thermal conducting behavior and anti-corrosion properties of the whole photovoltaic system.
Fig.1 Schematic structure of soft substrate Fig.2 Thermo-processing procedure Bonding material here is EVA resin, which are fine white powder materials before they are heated to bond the whole structure together.
The materials for the design structure in Fig.1 are put in an oven with a microchip through which parameters like heating rates and time period can be accurately controlled.
This value is much higher than the concentration recommended by ASTM standard for the rubber materials which is within a range between 50 ppm to 250 ppm [6].
