如达不到要求，可对色谱分离条件作适当的调整。
If it fails, appropriate adjustments can be made to the spectrum separating conditions.
并从色谱热力学函数分析了保留指数随温度变化规律的主要原因是由于在色谱分离过程中不同的熵变和焓变所造成的。
The changing law of retention index with temperature from chromatographic thermal function resulted from the variation of the different entropy and enthalpy during the chromatographic separation.
对它们的分离一直以来都在研究，传统的方法有凝固点法、气相色谱法，但是分离效果均不理想。
The separation of them is studied all the while. Traditional methods include freezing point and gas chromatography, But the effect of separation is not so good.
