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。

The comprehensive evalucation resulted in a strong drought resistance group including ZXY04P-201、ZXY03P-227、ZXY03P-122 and ZX Y04P-136, a weak drought resistance group including ZXY04P-101、ZXY04P-89,ZXY04P-239 and a intermediate group including the others according to the the above indicators. 3. The results of study on drought mechanism for 4 Dactylis glomerata L. under continuously water stress and rewatering show: the water saturation deficit of leaves arose hastily, and ZXY04P-239 changed most obviously while ZXY04P-201 changed only slightly under drought stress. ZXY03P-173 and ZXY04P-201 increased in the relative plasmalemma permeability and the soluble sugar content while thant of ZXY04P-75 and ZXY04P-239 showed the trend of initial increasing, reaching the peak at the 8th day, then decreasing under drought stress.

At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.
