On the basis of pollen analysis of surface sample in North China, polynomial function analysis method was applied to establish pollen climate response surface of Pinus, Betula, Quercus, Artemisia, Chenopodiaceae, Compositae, Picea, Ephedra, Gramineae in North China, therefore an easy and applicable method for reconstructing palaeoclimate and palaeoenvironment with data of fossil pollen was founded; Multi-analysis method was applied to analyse the principal elements of surface sample pollen in central Inner Mongolia Steppe, the assemblages of surface sample pollen in steppe area and its relationship with vegetation type were discussed with helps from spore-pollen analysis of a peat section in Chasuqi, Inner Mongolia and 〓C chronometer, fossil pollen data were obtained with high resolution on the peat section in Chasuqi. Vegetation succession and environmental changes since Holocene at resolution of 70 years were primarily reconstructed in south Mount Daqingshan and Plain Tumete. The changes in the area were copmared with those in the neighbouring areas during the same period. It was found that Holocene environmental change had undergone the following stages: cold-arid, temperate-wet, warm-wet, temperate-arid and cold-arid, and the climatical optimum period occurred in 5000-4100 aB.

The strain and temperature resolution is 30με and 3℃, respectively. 6. Several typical demodulation method using optical filters, including quasi delta function demodulation, linear function demodulation, matrix function demodulation and trigonometric function demodulation, is presented and discussed. We research the matched-grating demodulation and a high wavelength resolution of 2. 6pm is reached.

分析和归纳了几类较为典型的滤波解调制方法（包括：类δ函数解调制、线性函数解调制、矩形函数解调制和三角函数解调制），对这几类方法如何实现做了简单讨论，并对匹配光栅解调解调技术进行了理论分析和实验研究，这种检测方案的波长分辨率可达2.6pm。

In the case of racemate 2, better resolution was obtained when using 2-propanol as modifier in the place of methanol and ethanol, while for racemate 1, methanol provided the best performance. Both retention and resolution decreased with increase in pressure.

结果表明对映体的保留因子均随着改性剂含量的增加而显著下降，当改性剂含量大于10%时，保留因子的下降趋势变缓；分离帕罗酮酯时，异丙醇作改性剂的分离度和分离因子均最大，分离帕罗醇对映体时，甲醇是最佳的改性剂。
