云南省语言文字工作研究

为贯彻实施国家有关语言文字工作的政策法规,云南省语言文字工作部门在省委、省政府的领导下做了大量工作,取得了一定的成绩。随着改革开放的深入,云南的语言文字工作密切结合云南社会经济文化发展的需要,更显示出一种崭新的面貌。尤其自2001年1月《中华人民共和国国家通用语言文字法》颁布实施以来,云南的语言文字工作日益走上法制化的轨道,各项工作有法可依,有章可循,使原有的成绩更加巩固,存在的问题逐步解决,语言规范的意识日益深入人心。

努力提高小学教师的专业化水平

全面建设小康社会,满足少年儿童和千千万万家庭享受高质量的小学基础教育,在经济、政治条件基本具备的情况下,关键取决于小学教师队伍的专业化水平。经过多年的努力,云南小学教育的质量水平有了明显提高,涌现出了在全国也毫不逊色的优秀学校和教师,但是这类学校和教师的绝对数量不多,多数学校的教师学历结构层次水平偏低,专业化水平不高,教育质量水平不尽如人意。因此提高现有小学队伍专业化水平就成了振兴云南基础教育的关键之一。提高现有小学教师队伍专业化水平的途径仍然是要加强学历教育和非学历教育,但二者必须按教师专业化目标统一起…

人参属植物的三萜成分和分类系统、地理分布的关系

 This article deals with the distribution of triterpenoids in Chinese: species of Panax.  The results of investigation show that the tetracyclic triterpenoids of dam- marane type are the main constituents in Ginseng (P. Ginseng C. A. Meyer) and Sanchii (P. notoginseng (Burk.) F. H. Chen) and that pentacyelic triterpenoids of oleanane type are the main constituents in P. pseudo-ginseng Wall., P. zingiberensis C. Y. Wu et K. M. Feng, P. japonicus C. A. Meyer and its variety (var. angustifolius, var. major, var. bipinnatifidus) and P. stipuleanatus H. T. Tsai et K. M. Feng.  The fact that the Chinese people had found out herbs with such high therapeutic effects as Ginseng and Sanchii through long medical practices shows it to have been achieved not without modern scientific ground.  Tetracyelic triterpenoids of dammarane type is one of the active constituent of Ginseng and Sanchii, while, on the contrary, the pentacyclic triterpenoids of oleanane type have yet inactive physiologic properties. '      Through the comparative study of triterpenoids constituents together with the taxonomy and the geographic distribution of various species of Chinese Panax, it shows that Panax as a whole may be divided into two main groups: the first group, having rather short erect rhizomes, fleshy carrotlike roots and larger seeds, is cor- responding to those species with their main constituents as the tetracyclic triterpenoids of dammarane type and their areas in dispersal being often limited and disjunct. The second group, that possesses long creeping rhizomes, usually with no well developed fleshy roots and bearing smaller seeds, correlates to those species invariably with continual distribution and their main constituents are pentacyclic triterpenoids of oleanane type.  Therefore, it is suggested that in comparing with the latter group, the former is perhaps more primitive, and Sanchi  (P.  notoginseng  (Burk.)  F.  H. Chen) may be the oldest member among living species of Panax. On the other land, it is found that in external morphology, P. pseudo-ginseng Wall. belongs to the former group, but its chemical constituents are nevertheless similar to the latter.  On such account, it seems evident that P. pseudo-ginseng Wall. constitutes a transitional type between these two groups, and reveals there by some historical relationship of thesetwo groups.
