当洗脱体积为床体积的2倍时，黄酮的解吸速度很快。
The desorption of the flavones is fast when the elution volume is 2 times of bed volume.
你引用的规则是用于覆盖全范围梯度洗脱的（例如，有机溶剂从5改变到100%），并且所指的体积是以初始条件来重新平衡。
The rule that you quoted is intended to cover a full-range gradient (for example, 5–100% organic solvent) and refers to the amount of volume to reequilibrate at the initial conditions.
在此条件下，用体积分数60%乙醇洗脱得水解鞣质纯度为71.03%。
Under these conditions, hydrolysable tannins were eluted with 60% ethanol, the purity of which is 71.03%.
而30%乙醇（6倍柱床体积）和50%乙醇（6倍柱床体积）组合是最佳动态洗脱剂。
The optimal eluting solvent was the water solutions of 30% ethanol(6 times of resin volume) and 50% ethanol(6 times of resin volume).
乙醇洗脱速度快，洗脱彻底，洗脱剂用量为2倍柱床体积（BV）。
The desorption of the flavones is fast and complete with 95% ethanol when the elution volume is 2 times of bed volume(BV).
预测了台阶梯度洗脱条件下待分离物质的保留体积。
The retention volume of targeted compounds was predicted in the step gradient elution conditions.
抗惊厥试验结果：天王补心丸SP825体积分数为0.2和0.5乙醇洗脱部分均能够明显延长戊四唑所致小鼠阵挛性抽搐的潜伏期（P<0.05）。
Pentylenetetrazole induced eclampsia: Both SP825 0.2 and 0.5 alcohol fraction could remarkably prolong the latency of clonic convulsion induced by pentylenetetrazole( P< 0.05).
