【Abstract】 Anaerobic fermentation characteristic of dairy cattle manure at 20-30 ℃ was systematically stud-ied through dual quadratic rotary combinational design in this paper.Under the condition of certain varying range,the regularity of biogas production rate was gotten.The results obtained from the pattern were the same as the actual experimental results.They could afford warranty for studies afterwards.更多还原
