5.Dranchuk Abu Kassem model (DAK model) is the most frequently used for calculating gas compressibility factor. Its application showed that the method was not accurate enough for calculating the compressibility of high pressure gas.
目前计算高压下天然气偏差系数最常用的是Dranchuk Abu Kassem模型 ,但在实际应用中 ,这种模型的计算结果存在较大的误差。
6.The degrading rate of 50 mg/kg MP in non-sterile and sterile soil of chemotaxis mutant DAK is about 20%～30% lower than that of wild-type bacterial DLL-1.Lose of chemotaxis in DLL-1 would decline its degradation ability of MP. It was demonstrated that chemotaxis plays an important role in the in-situ biodegradation of pesticides.
通过土壤盆钵试验(MP浓度为50mg/kg),发现在灭菌与未灭菌土壤中趋化突变株对MP的降解能力低于原始出发菌株DLL-1约20%~30%,说明菌株DLL-1趋化性的丧失会减慢其对农药的降解,趋化性在农药的原位降解过程中发挥重要作用。
