谢谢大家  其中止痛灵的英文是ethenzamide

Different concentrations of ethenzamide UV absorption curve.
Ethenzamidei's solubility in different solvents at different temperatures.
Solubility of different solvents changes with temperature.
The productivity of crude product after recrystallizing in different solvents.
Absorption curve of different solvents
Absorption spectrum with solvent of anhydrous methanol.
The constant concentration (67.104ug/ml)'s absorption of ethenzamide at different temperatures.
Determination of intra- and inter-day precision .
Determination of different concentratiions (g/ml)/specific absorptivity.
Recovery experiment.

上面的翻译有些错误,下面是我的翻译:
(1)Different concentrations of ethenzamide UV absorption curve应该为
The ethenzamide UV absorption curve of different concentrations
(2)Determination of different concentratiions (g/ml)/specific absorptivity.应该为
Determination of different concentratiions (g/ml)/apparent percentage      absorption coefficient  
(3)Recovery experiment应该为
recovery rate test

自己也长学问了， 谢谢.
