According to the formula（10）, it should be noted that the structure and intensity of the dispersal equipments and the mass ratio of explosion and fuel and the property of explosion and fuel is not taken into accounts.
The results of experimental study indicate that, when the explosive is detonated, a lighting ball beyond the vision of field appears and soon shrinks, and then the structure of a fireball is clear.
The fireball involves complex chemistry reactions, such as the reaction of aluminum and oxygen in air or explosion products, which require a more intact reactive mechanism to account for this phenomenon.

Hydrothermal synthesis and photocatalytic activities of La-doped BiVO4 microcakes Guocong Liu1, a, Shihua Xu2,b , Yinjian Liang1,c 1Department of Chemical Engineering, Huizhou University, Huizhou 516007,China 2 College of Chemistry & Ecological Engineering, Guangxi University for Nationalities, Nanning 530008, China.
To further improve the photocatalytic activities of BiVO4 with polymorphic structures, the nanocasting strategy, metal-doping technology, heterozygote of metal oxide, and highly ordered three-dimensional (3D) superstructures have been reported.
In this paper, lanthanum element was chosen for doping BiVO4 using template-free hydrothermal process, and uniform Bi1-x LaxVO4 microcakes can be controlled only by changing the pH values of the solutions.The substitution of bismuth by lanthanum might change the energy band structure of BiVO4 crystal, which will enhance the photocatalytic ability.The photocatalytic property of the hybrid BiVO4 was examined by measuring the degradation efficiency of methyl blue (MB) under visible light irradiation, confirming that La-doping BiVO4 is effective to some organic pollutants.

(TPU, Department of General and Inorganic Chemistry) [7].
It is possible to go on by increasing the sintering temperature, but it is inevitable recrystallization of sintered material, the result of which will be coarse-grained structure of the sintered ceramics.
This structure leads to the degradation of strength properties.

Measurement and Control System Inverter Solar Energy Controller Load Figure.1 Schematic of off-grid power systems since tracking Solar orientation during tracking, since feedback signals are tracking signals, and the actual structure of the actuator is mechanical, due to limited control interval, and a slight error in the operation of each machine, the solar photovoltaic power generation will lead to a long time the huge accumulation of errors, making a serious deviation from the solar collection panels solar orientation.
Conclusion Tracking devices generally have gear or worm gear structure, the overall tracking accuracy is poor, suitable for non-concentrating photovoltaic systems, solar orientation if you want to achieve high-precision tracking concentrating photovoltaic power generation system to adapt to the precise moment the sun is on the requirements, the need to manufacture high-precision tracking devices or high-precision worm gear and precision servo system, the high cost.
