In the light of field features in desertification areas, the data quality and band combination of different bands are assessed, the indicators, principles and methods for data assessment and band option are put forward to, and optional band combination for desertification monitoring is determined primarily. The data pre-treatment model for desertification monitoring is developed after studying the pre-treatment algorithm of restoration and rebuilding of hyperspectral resolution data. The spectral features and variation rules of different objects in experimental areas are understood and analyzed. The different classified methods are given and discussed on the basis of characteristics of desertification region. The remote sensing quantitative retrieval model for the appraisable factors of desertification monitoring are founded.

The experimental results show that the mean particle size of griseofulvin precipitated by RESS is smaller than 1, 0μm, narrow distribution and 95％ fine particles is smaller than 1. 0μm. Increase of the pre-expansion pressure, the extraction temperature, the expansion chamber temperature, the spraying distance, the concentration of cosolvent and decrease of the nozzle diameter resulted in decrease of the particle size under the operating condition studied. Enhancement of the pre-expansion temperature resulted in increase of the particles size. The SEM of GF shows that the shape of original is atactic and a wide size distribution, but the microparticles obtained by RESS is reverse. Similar melting points and XRD patterns were observed for the original material and the precipitates obtained by RESS.

实验结果表明，用含夹带剂的RESS法制备的灰黄霉素微粒的平均直径在1μm左右，且分布均匀，95％微粒在1μm以下，仅用CO〓作为超临界流体制备的微粒与上述方法制备的微粒的平均直径和分布相似，只是产量太低，而用机械法制备的微粒平均直径在3μm左右且分布较宽；不同的过程参数对沉析微粒尺寸有不同的影响，预膨胀压力、膨胀室温度、溶解温度以及夹带剂浓度的提高或增大，均可使沉析微粒的直径变小；预膨胀温度提高，所得微粒的直径变大；喷射距离的增加，沉析微粒的直径变小；喷嘴直径越小，由此制得的微粒的直径就越小；根据实验结果还可知道，通过理论计算的马赫盘处微粒的直径可以较好地估计出膨胀室中收集到的微粒的直径。
