D-valueD值
1.By this method, the D-values of three foodborne pathergens, Escherichia coli , Salmonella paratyphi B at the temperature of 50 ,55,60 ℃ and Staphylococcus aureus ranges from 55～65 ℃ in water bath and microwave heating were determined.利用此方法,分別測定了三種食源性致病菌,大腸桿菌(Escherichia coli)、乙型副傷寒沙門菌(Salmonella paratyphi B)在50,55,60℃水浴和微波加熱殺菌的D值,以及金黃色葡萄球菌(Staphylococcus aureus)在55,60,65℃水浴和微波加熱殺菌的D值。
2.We use D-value method to fast determine the efficacy.本文研究了綠茶和桑葉提取物在不同濃度時對細菌的抑制作用,采用D值計算法快速評價了它們的抑菌效果。
3.By comparing the D-value of both microorganisms,it is found that Escherichia coli are killed more easily than staphylococcus aurous.通過對滅菌D值的比較發現大腸桿菌(革蘭氏陰性菌)較之金黃色葡萄球菌(革蘭氏陽性菌)易于滅殺。
3)d/D rated/D值
1.Based on the RTD (Residence Time Distribution) experiment and in-tandem model, this paper mainly discussed how the d/D rate and the rotating velocity of fluid director (n) influenced the flow pattern of SUFR.介紹了螺旋升流反應器流態試驗的思路及原理;并通過壽命停留時間分布(RTD)試驗及多段串聯模型,探索d/D值及導流轉速(n)對螺旋升流反應器的流態的影響規律;由正交回歸試驗得到:當d/D=0。
4)R/D ValueR/D值
5)d table methodd值表法
6)displacement value〔d〕d值位移
1.We have studied the variation rules of widening of diffraction line profile,〔020〕displacement value〔d〕,grain size,endothermic effect and hydroxy vibration,The results demonstrate that the s.研究了衍射峰線形寬化、〔0 2 0〕d值位移、晶粒度、吸熱效應、羥基振動等變化規律 ,進而提出了擬薄水鋁石的結構為〔AlOOH〕·nH2 O ,n為 0 0 80～ 0 6 0 2。
