| 1 | Photoreductive degradation of sulfur hexafluoride in the presence of styrene显示文摘硫 hexafluoride (SF6 ) 在空气作为最强大的温室气体之一被知道。由苯乙烯的 SF6 的减少的相片降级被学习了以达到为硫 hexafluoride 污染开发新奇补习。破坏和 SF6 的移动效率(DRE ) 上的反应条件的效果在这研究被检验。两起始的 styrene-to-SF6 比率和起始的氧集中对 DRE 施加重要影响。SF6 移动效率在 0.2 的起始的 styrene-to-SF6 比率到达最大的价值。DRE 与增加氧集中在 0 ~ 0.09 mol/m3 然后减少的范围上与氧集中增加,这被发现。当水蒸汽被喂进煤气的混合时, DRE 稍微在整个学习时间规模上被提高。X光检查光电子光谱学( XPS )分析,和煤气的层析团,光谱测定( GCMS )和 Fourier 转变红外线的光谱学(英尺红外)分析,证明那是将近居住在煤气的阶段的起始的氟的符号在 SiF4 形式的所有,而,起始的硫在元素的硫形式被扔,在相片降级以后。从有毒的副产品免费,相片降级可以为 SF6 消退面对苯乙烯用作一种有希望的技术。 | HUANG Li GU Dinghong Yang Longyu Xia Lanyan ZHANG Renxi HOU Huiqi | 2008 | Journal of Environmental Sciences2008，20，2： | 5 |
| 2 | Effect of Cryopreservation on Seed Viability of 4 Species显示文摘In order to explore the feasibility of cryopreservation on dormant forest tree seeds,the seed viability of 4 species(Malus baccata,Prunus davidiana,P.armenica and Amygdalu persica) with moisture content(MC) changing was tested after 30-day storage in liquid nitrogen of -196℃.The results showed that all the 4 species of seeds can keep a stable viability after cryopreservation.In the procedure,the optimum MC was 48 g/kg for M.baccata,27 g/kg for P.davidiana,31 g/kg for P.armenica and 45 g/kg for A.persica,... | LIU Yan~1 LI Qingmei~(2**) LIU Guangquan~(1**) DUAN Xinfang~3 HOU Longyu~1 1.International Research and Training Center on Erosion and Sedimentation,Beijing 100044,P.R.China 2.Research Institute of Forestry,Chinese Academy of Forestry,Beijing 100091,P.R.China 3.Institute of New Forestry Technology,Chinese Academy of Forestry,Beijing 100091,P.R.China | 2009 | Chinese Forestry Science and Technology2009，8，2： | 2 |

| 5 | Seasonal distribution of increased precipitation in maternal environments influences offspring performance of Potentilla tanacetifolia in a temperate steppe ecosystem显示文摘Aims Precipitation is predicted to increase in arid and semiarid regions under climate change,with greater changes in intra-and interannual distribution in the future.As a major limiting factor in these regions,changes in precipitation undoubtedly influence plant growth and productivity.However,how the temporal shifts in pre-cipitation will impact plant populations are uncertain.Methods A 3-year field experiment and a greenhouse experiment were conducted in a temperate grassland in northern China to examine the impacts of seasonal(spring and summer)increased precipitation on offspring performance of a common species,Potentilla tanacetifolia.Important Findings Our results showed that the amounts and timing of increased precipitation both played important roles in regulating offspring performance of P.tanacetifolia in the temperate steppe ecosystem.Increased precipitation in spring at maternal stage stimulated seed production,germination percentage and seedling biomass,whereas increased precipitation in summer at maternal stage stimulated seedling biomass.The timing of increased precipitation influenced seed attributes,whereas the amount of increased precipitation influenced offspring seedling biomass.Our results indicate that population development of P.tanacetifolia may be underestimated under future increased precipitation regime,if the transgenerational effect is not taken into account. | Yang Li Longyu Hou Bing Song Shiqiang Wan Xiaoqin Sun Linghao Li | 2019 | Journal of Plant Ecology2019，12，4： | 1 |

| 7 | Effect of Moisture Content on Melilotus suaveolens Seed Quality During Ultra-drying Storage显示文摘In order to enhance the seed storability and supply high-quality seeds for vegetation restoration in the arid and semi-arid regions in Northwest China,the effects of ultra-drying and accelerated aging on the physiological characterstics of Melilotus suaveolens seeds were studied.Melilotus suaveolens seeds were dried in a desiccator containing silica gel to 80,53,42,33,23 and 16 g·kg-1 of moisture contents(MC),respectively.The parameters of the seed quality including germination energy(GE),germination percentage(GP),relative conductivity(RC),dehydrogenase activity(DA) and α-amylase activity(AA) were determined after ultra-drying and accelerated aging.The results showed that ultra-dried seeds with 42 g·kg-1 of MC showed the minimum changes of GE and GP before and after seed aging.Moreover,ultra-dry seeds with 42 g·kg-1 of MC showed higher DA and AA,and lower RC than non-ultra-drying seeds.Therefore,ultra-drying to 42 g·kg-1 of MC was helpful for M.suaveolens seed storage. | LIU Yan LIU Guangquan LI Qingmei DUAN Xinfang HOU Longyu | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，1： | 0 |
