According to the present situation of coal industrial development ,we have analysed some safety problem that arouses from methane gas, introduced the mature and potential application of vacuum equipment to this profession, and put forward that the application of vavuum pump to the coal industrial, can meet safety demand, accord with the basic national policy of the circulating economy, energy saving economy and continuable development.
secondly, the safety management design has been discussed, thereafter, safety management theory is employed to discuss classification of accidents & causation of accidents and to analyze the potential risk in the gas&oil exploitation.
Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics
The explicit solution to Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics is given.
Photocatalytic Oxidation of Aniline in the Gas Phase Using Porous TiO2 Thin Films
The gas-phase photocatalytic oxidation of aniline on a new kind of porous nano-TiO2 composite films is investigated.
Acetone solution-casting films of poly(methylmethacrylate) were analyzed by differential scanning calorimetry and pyrolysis gas chromatography-mass spectroscopy under natural evaporation and ultrasonic vibration, respectively.
