Highly porous "Gamma Alumina" is commonly considered as one of the most prevalent nanomaterials employed as a source of metal catalysts which has a spinal structure [15]. γ-Al2O3 is a top catalyst widely employed for industrial purposes in large part due to its relatively vast surface area, unique surface properties, and outstanding structural stability [19]. γ-Al2O3 has a cubic spinel structure and can effectively transform into alpha-alumina at sintering temperature before inverting at 1150 °C.

The application and analysis of the risk assessment model about BLEVE accident Fei Xie1,2,a, Wen-hua Song1,b, Zhen Chen1,c,Ling-yue Lv1,d 1.Environment and Chemistry College, Tianjin Polytechnical Univeisity, Tianjin China 2.Tianjin City Public Security Fire Station, Hexi District Fire Brigade, Tianjin, China ae-mail:xiefei820818@126.com be-mail: songwenhuateam@sina.com ce-mail: chenzhen3419@126.com de-mail: yiqiandshowlove@126.com Keywords：BLEVE; TNT equivalent method; 1,2-dichloropropane tank area; risk assessment; overpressure wave; Abstract：The flammable vapor pressure inside the combustible liquid storage tanks in the fire environment elevates, and the of the tank wall the yield strength of enduring the heat decreases, which cause the collapse to occur soon, resulting in the happen of BLEVE.
Refinement of the BLEVE concept in the light of the information available from the past accidents,and substantiation by controlled experiments,has led Venart and co-workers[9] to suggest that a complex two-step failure process involving fluid structure interaction may be the cause of all the BLEVES.
The fire protection embankment in the tank area is reinforced concrete structure.

Furthermore, Zhao Xianrui also made description of the principle of supercritical fluid refinement technology, the technological conditions for preparation of ultrafine RDX、HMX and the advantages of technological industrialization of supercritical fluid etc.[10] 4.The method of ultrasonic wave refinement The principle of ultrasonic wave crushing is [11]: firstly, energy is delivered by the high-frequency ultrasonic vibration to solid particles in the liquid, and then solid particles will be crushed (or depolymerized) when energy received in the particle inside is enough to overcome the binding energy of solid structure.
The special sonifier can crush explosive crystals into the particle of which volume average diameter is only10um, and the sonofier is effective for particles whose ultrasonication structures are loose but not for crystals in which particles are dense, but it is quiet effective for exploding aggregation of ultrafine particles.

This figure clearly shows the existence mixed phases of fluorophlogopite and MgSiO3 in the form of large flake like structure and fine grains.
Fig. 2(b) shows the SEM picture of the sample having 12.34 mol% of Al2O3, which shows the presence of only one phase namely the fluoro- phlogopite, has got plate like structure dispersed in glassy phase.

The sintered Al-6%Cu compact shows a relatively dense structure and particle boundaries and pores are mostly filled with a second phase which must be a liquid phase which persisted during the sintering.
EDX analysis of the sintered structure revealed that the matrix contains about 4.5% copper which is much higher than about 2% in a sintered Al-6%Cu and the solidified liquid phase contains about 45% copper, which is lower than in Al-6%Cu, without any zinc.

The composition of the films and the ion implanted surface of the substrate were measured by Rutherford backscattering spectrometry and the structure of the films was analyzed by Raman spectra.
In indicated the structure of DLC films on ion implanted substrate was similar with that of normal DLC film.
