The separation of tocopherols and tocotrienols by using the method of adsorption chromatography on silica and on silica impregnated with silver nitrate have been discussed. Satisfactory separation could be obtained with argentation column chromatography by eluting batchwise with n-hexane containing increasing amounts of diethyl ether. More than 90% of vitamin E amount in eluate was tocotrienols.

以乙醚正己烷混合溶液为淋洗液，探讨了硅胶柱层析和硝酸银硅胶柱层析分离生育三烯酚和生育酚的效果，结果表明：通过改变淋洗液中乙醚含量可以将生育酚和生育三烯酚大部分分离：硝酸银硅胶柱层析分离生育三烯酚和生育酚的效果明显高于硅胶柱层析，其洗脱液中生育三烯酚可占V〓总量的90％以上，最高达98.47％。

According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.

从模拟结果中得知，薄膜型结构之太阳电池可以经由AuGe/Au之金属反射层，再次将未被基极层完全吸收之入射光反射回太阳电池，使得薄膜型结构在长波段的外部量子效率获得提升，这结果显示薄膜型结构太阳电池可利用AuGe/Au之金属反射层在长波段的高反射率，改善使用较薄基极层时，无法将入射光完全吸收的缺点。

The higher contract rate and the quicker healing speed appeared in treat group. The result from the hematoxylin and eosin staining showed that the epidermis is thicker in treat group than that in control group. A few BrdU positive cells appeared on the hair follicle of the rengenerate skin and the stratum basale and the stratum of the rengenerate epidermis.

Whereas, the tapetum of Zhenshan 97A disaggregated at the pollen mother cell stage, the nuclear membrane and the cell membrane disaggregated, the phenomena continued to the binucleate pollen stage. The cytoplasm of the tapetum cells of Zhenshan 97A deposited a few Ca^2＋ precipitates at the pollen mother cell stage.

珍汕97A绒毡层细胞从花粉母细胞时期开始，细胞质内有少量颗粒状的Ca^2＋沉淀；减数分裂时期，绒毡层细胞的内切向壁表面有大量大颗粒的Ca^2＋沉淀；单核花粉时期绒毡层细胞周围集聚一层Ca^2＋沉淀。

The 28S rDNA molecular phylogenetic trees showed: 1 entoprocts and phylactolaemate ectoprocts constituted a sister group, strenghthening the opinion that entoprocts should be reunited into phylum Bryozoa; 2 the cheilostome gymnolaemates was obviously non-monophyletic; 3 bryozoans itself was polyphyletic beyond any doubt, its main lineages were scattered in different positions of the lophotrochozoan trees; 4 to our great interests, the phylogenetic position of cheilostomes was between the diploblastic and the triploblastic, indicating they may play an important role during the evolution route from the diplobastic to the triploblastic animals.

28S rDNA分子系统树显示，内肛动物和被唇类外肛动物聚在一起并互为姐妹群，支持将内肛动物重新归入苔藓动物门的结论；唇口目裸唇类外肛动物绝非单系发生；苔藓动物本身也不是单系发生的，其主要类群分别位于触手冠担轮动物系统树的不同位置，特别是，唇口目苔藓动物的系统地位介于二胚层动物和其它三胚层动物之间，可能是二胚层动物向三胚层动物演化过程中的一个关键类群。
