The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

高大建筑物、乔木及灌木遮荫会使用于城市绿化的草坪草受到严重胁迫，造成草坪草衰退，针对这一难题进行了研究；以耐荫性不同的冷季型草坪草匍匐紫羊茅派尼、草地早熟禾肯塔基、匍匐翦股颖摄政王为试验材料，研究了不同浓度的外源激素稀效唑(Uniconazole， S3307)处理对3种遮荫草坪草生理及生长变化的长期调控作用；经稀效唑处理，3种草坪草叶片叶绿素含量和可溶性糖含量增高，植株株高变低，叶片变宽、变厚，不同耐荫性草坪草的耐荫能力均得到显著提高，最适的处理浓度范围100~200mg/L；这在生产实际中有重要应用价值，特别对提高受遮荫胁迫的草坪质量具有重要意义。

Teach an activity this especially, it is the Party Central Committee what make through cogitative, consider the situation is great and decision-making, it is to insist to use " 3 delegates " serious thought arms entire party, those who raise a party be in office the ability, significant move that drives line of business of important matter of Wei of Chinese characteristic socialism in the round.

From Karl Marx to Mao Ze-dong, especially Deng Xiao-ping, all paid much attention to the important position of the productive force in the Party's line, guiding principle and socialist development. The inheritage and the development of these important thought's theoretical origin is that the Party must become the loyal representative of Chinese advanced social productive force. Mao Ze-dong and Deng Xiao-ping combined Marxism with Chine...

从马克思到毛泽东，特别是邓小平，都十分重视生产力在党的路线、纲领及社会主义发展中极其重要的地位，对这些重要思想的继承和发展是&党要成为中国先进社会生产力的忠实代表&思想的理论渊源；毛泽东、邓小平把马克思主义与中国革命和社会主义建设实际相结合形成的、以毛泽东思想和邓小平理论为指导的新的文化理念，奠定了&党是中国先进文化前进方向的忠实代表&思想的理论基础；中国共产党为广大人民最根本利益而奋斗的历史经验，以及毛泽东、邓小平所一贯坚持的群众路线，则与&党始终是中国最广大人民群众的根本利益的忠实代表&思想是一脉相承的

The study of molecular spectra is an important tool for understandingthe structure of molecules. The exploration of the microcosmos relies on spec-troscope to a great extent. In recent years, profited by the development ofexperimental techniques in high resolution spectroscopy, experimental data onmolecular spectra are more and more precise, so the theoretical analysis ofthem has become an important subject on chemical physics.
