It is the change of physical properties of system that makes the extractability increase.
萃取率的上升是因体系物理性质发生变化而造成。
2
The data illustrated the extractability was slightly increased in the magnetic field, which could be explained by the same extraction principle.
研究结果认为：在磁场作用下稀土的萃取率稍有升高，萃取机理不变。

The structural variation of the hydrocarbyl groups in the extractant molecules has the different influences on the extractability of various metal ions.
