in the following subsection according to the traffic conditions and mobility of the users. The CP scheme is not considered here because of its poor efficiency in terms of resource utilization [3, 14]. 2.3... efficiency and quality of service (QoS) required for different services in a very scarce resource as the radio spectrum. A new scheme was proposed which extends the concepts of resource sharing......
Experimental investigation on atomization and collecting efficiency ofwind-spray dust controller and its parameters optimizationKOU Bao-fu(寇保福)1, LIU Qiu-zu(刘邱祖)1, CAO Shi-chen(曹世宸)2, HU Xiao-he(胡晓禾... of Science and Technology Beijing, Beijing 100083, China)Abstract:In order to enhance the atomization efficiency of atomizer, a new type of wind-spray dust controller combining the rotary-atomization......
(OH)3 precipitation efficiency and induction period of bayerite were investigated. The results indicate that the neutralization curve of the artificial chromate alkali solutions shows three distinct... 50 °C to 70 °C. Coarse bayerite with particle size (d50) from 24.2 μm to 29.3 μm extremely has few impurities, which is suitable for comprehensive utilization. Key words......

Technology, Changsha 410083, China) Abstract: To analyze the situation of comprehensive utilization of different kinds of resources such as material, energy, funds, labor force, the concept... such as utilization coefficient of universal exergy and sustainable development index were defined. Universal exergy analysis method and the models were used to evaluate a SKS lead smelting system......
that the tumbling index and finished products efficiency increase with increasing coke dosage, while decrease with increasing basicity. Sinter spontaneous pulverization becomes severer as basicity increases. The tumbling index is 69.1%, finished products efficiency is 81.2%, sintering speed is 30 mm/min and productivity is 1.2 t/(h?m2) under the conditions of moisture of 9.0%, coke dosage of 8.0......
, the minimum requirement and utilization of reducing gas depend on the actual requirement and thermodynamics efficiency of the key stage. In reduction process, only the second or third stage may become... in reduction course is the 3rd stage (FeO→Fe), and the utilization of reducing gas increases with the rise of H2 proportion. Key words: iron ore pellets; coal gas; gas-based direct reduction; reduction kinetics......
