Expression of atnced3 driven by 35s promoter , rd29a promoter or kst1 promoter has greatly affected the growth and stomotal movement and drought tolerance in the transgenic tobacco plants . we observed the 35s : iatnced3 plants showed severe growth retarda - tion , and vd29a : atnced3 plants exhibited slight growth retardation , however we also observed the kst1 : : atnceds plants had a good growth under normal conditions 比较了35s 、 rd29a 、 kst1启动子驱动atnced _ 3的表达对烟草生长和气孔运动以及抗旱性的影响，结果表明35s转基因植株明显生长矮小，发育滞后； rd29a转基因植株生长也比野生型慢一点； kst1转基因阳性苗表型最好，在正常条件下生长旺盛。
In this work , the transgenic plants showed a tendency to accumulate less na + and more k + under saline condition than wild type plants and there was a high cytosolic k + / na + ratio in the roots of transgenic lines . 5 . x - ray microanalysis of na + , k + contents of the symplast and apoplast showed that transgenic lines accumulate less na + and more k + in the symplast than wild type plants 在对转基因植株及野生型植株用100nunol lnaci处理六天后， na ” 、 k ”的x一射线微区分析，转基因植株根、叶中质外体na 、 k十含量变化不大，但共质体中na十含量明显降低，广含量高于对照。
The results of performance testing showed that the additive of nano - powders can evidently enhance the latex coatings " weathering resistance , scratch resistance , water resistance and alkaline resistance , and do not reduce other performances ; polybasic nano - composite powders have more efficient than single nano - powder ; the dispersing method have biggish effect on performances . observing the stability of nano - additive of exterior latex coating showed there was no viscidity rising , no delaminatiom sedimentation in two months . tryout by plant showed that nano - weatherability additive can obviously enhance the weathering resistance of latex coating and water resistance , and no reducing other capabilities 对其性能研究的结果表明，纳米粉体材料的引入，可以明显提高乳胶漆的耐候性、耐洗刷性和耐水耐碱性能，对其它性能无不良影响；纳米多元复合粉体比单一粉体的改性效果明显；纳米粉体的添加工艺对改性乳胶漆性能有较大的影响，采用同普通填料一致的添加方式制备的试样与采用超声波预分散后在配漆阶段加入制备的试样相比，后者在稳定性、耐候性等方面的性能都有所提高。
Practice of application on two boilers in rizhao power plant shows that the adjustment of detection distance not only can solve the problem of somewhat low indicating value for very few flame detectors , but also can save large amount of fuel oil used for stabilizing combustion , having remarkable economic benefit under condition of stable ignition and combustion for pulverized coal and air flow 日照电厂2台锅炉的应用实践表明，在煤粉气流稳定着火燃烧的情况下，调整火检的检测距离不仅可解决个别火检指示值偏低的问题，而且可节省大量的稳燃油，经济效益显著。
Millet and tobacco were transformed with the thrt ' e plant expression vectors . our observations with transgenic plants showed that the pf40 gene affected the growth of lateral shoots developing in the basipetal pattern early after floral transition . analysisd the transgenic plants showed the pf40 gene can reduced the apical dominance of both millet and tobacco 测量结果表明pf40基因过量表达的转基因谷子生长素的含量降低为对照的0 . 6 0 . 8倍，而细胞分裂素的含量较对照约升高0 . 2 0 . 35倍，生长素与细胞分裂素的比值在转基因植物中改变明显，降低到对照的一半。
The combinations of the various aquatic plants showed good maintainability in water garden . the concentrations of tp , tn were kept lower effectively in the experimental pool ii ( planted with emersed aquatic plants ) and pool en ( floating and floating leaf aquatic plants and submerged aquatics ) the concentration of tp and tn was relatively higher in pool i which only planted with potamogeton crispus 用挺水植物和浮叶、漂浮植物组成的试验池及用挺水植物、浮叶和漂浮植物、沉水植物组成的试验池比由菹草组成的单一层次结构的试验池更能有效地维持水体tp 、 tn含量，其景观也更为丰富。
The result showed that physiological response were mainly affected by concentration of peg and less affected by time of peg ( 6000 ) treatment . relative water content of leaves root activity , and growth of roots and plants showed a less reduction under 10 - 20 % peg ( 6000 ) treatment , but ratios of root cap , and contains of soluble sugar , contain of pro and potassium showed a less increase . all those just described indexes showed a marked change under 25 % peg treatment 在10 20的peg浓度胁迫下，叶片相对含水量、根系活力、根系及地上部生长量下降的幅度较小；根冠比、可溶性糖、脯氨酸( pro ) 、 k ~ +上升的幅度也较小，而在25的peg浓度胁迫下上述指标发生了很显著的变化，叶片相对含水量、根系活力明显下降，可溶性糖最大含量出现的时间较20浓度胁迫的提早3d ，且较20时的最大含量小，并在延长处理3d后又开始下降，根系和地上部的生长受到严重抑制，且地上部影响大于根系，根冠比显著增大，胁迫后期趋于恒定状态，生长几乎完全停止。
