查询词典 dissociation

The factors relevant to the running buffer and their effects on separation were investigated. The buffer solution composed of 30 mmol/L sodium borate and 2.4 mmol/L β-CD was found to be the most suitable electrolyte for separation. The second order dissociation constant range of honokiol was estimated. The content range of honokiol in Cortex Magnoliae Officinalis and was 3.42-5.98 mg/g, while the mean content of honokiol in its preparation 0.021 mg/mL.

Fusion dissociation can be achieved in different ways , dissimilar ocular targets(e. g., Maddox rod), vertical prisms , separate targets for each eye(e. g., in a stereoscope), or alternate occlusion(e. g., cover test).

5融合分离可采用不同的方法实现，如采用双眼视标差异法、垂直棱镜法、双眼视标分离法、交替性屏蔽法等。

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...

以磺胺二甲嘧啶为模板分子，分别用甲基丙烯酸和4乙烯基吡啶为功能单体，二甲基丙烯酸乙二醇酯为交联剂，采用牺牲硅胶法合成了磺胺分子印迹聚合物，通过静态吸附实验，系统研究了不同单体对聚合物识别性能的影响；Scatchard分析表明，以甲基丙烯酸为单体的聚合物具有较高的吸附能力，其离解常数Kd为959×10-4mol/L，最大表观结合位点数Qmax为3070μmol/g。

We mainly detected the TOF and angular distribution of photofragment, and get the anisotropy parameter β and the translational energy distribution. In addition, we calculated the geometries of the ground states, the excited states and the triplet excited states, and the transition electric dipole moments. According to these, the dissociation lifetimes of some molecules are calculated.
