The traditional idea of revolution in China was brought into"two - wheel revolution "category in the whole world extension by modern theoretical conversion at the beginning of the 20th century, that is ,the England meliorate revolution and the France violence revolution.
Using ab initio norm-conserving psendo-potential computational simulation method based on density functional theory, electronic structure and optical-electronic property of FeS2 have been artificially modulated in order to increase theoretical conversion efficiencies of solar cell.
The response surface methodology was used to optimize the transesterification reaction conditions of rapeseed oil,and the optimized conditions of the reaction was found: the molar ratio of methanol and oil is 1.5 ∶1,reaction temperature is 52 ℃,rotation rate is 200 r/min,lipase mass ratio is 10%,and reaction time is 10 h. Under these optimal conditions,48% of the oil was converted to its corresponding methyl esters(the theoretical conversion rate is 50%).

The excellent strain SB 9064 was obtained by means of isolation of single spore, mutation of monoploidy, fusion of cell. It is sugar tolerant, temptrature tolerant strain and possesses high ethanol producing activity and fast growing fusant in the ethanol fermentation. Ethanol fermentation was carried out using immobilized SB 9064 fusant cell from corn mash. All experiments were carried out at 38 40℃. The pH of the corn mash was kept at 4.0～5.0. The fermentation duration was continued for 20～22hours and the...

Ethanol fermentation was carried out using immobilized SB 9064 fusant cell from corn mash. All experiments were carried out at 38 40℃. The pH of the corn mash was kept at 4.0～5.0. The fermentation duration was continued for 20～22hours and the yield of ethanol above the ranged in 9.0%～11%. The theoretical conversion rate is more than 90%. The initial sugar concentration and residual sugar were 16%～20% and less than 1.0%, respectively. Studies on the morphologcal and biochemical characters of the SB 9064 fusant and its identification. It was identified as a Novel Yeast for High Ethanol Production.
