摘要本研究采用大肠杆菌GM133 rifr细胞和营养收集细胞HB214 strr进行适应性突变实验。在混合30min和2d 后添加链霉素杀死GM133基因型细胞，继续培养5d后，在选择平板上出现了一定数量的lac+strr基因型回复突变菌落。根据这些突变菌落的数量，估计在lac+突变产生之前，GM133和HB214细胞之间的接合频率分别为0.07%和7.47%。在培养了7d的选择平板上添加含链霉素...

We compute the quantum rate constant based on two extended stationary phase approximations to the imaginary-time formulation of the quantum rate theory. The optimized stationary phase approximation to...
Cross-Linked Hydroxy-Al-Montmorillonite as a Stationary Phase in Liquid Chromatography
Adsorption Chelation Cross-linked smectite Disubstituted benzene High-pressure liquid chromatography Hydroxy-Al Monosubstituted benzene Phenyl-urea Phosphate esters
2012/1/4
Quasi-spherical particles (7-µm mean diameter) were prepared from cross-linked hydroxy-Al-montmorillonite (basal spacing = 15.3 and 18.6 Å) by spray-drying. These particles (SP-CLM) were u...
