濕沉降物
英文
wet deposition-
The rising temperature in the cave, the lamp - light ' s toasting and the convictive air made the humidity of the whole or part of the cave descend, which made the speleothem sightseeing dry, cracked and weathering. the acid air from the outer and the highly dense co2 would cause acid erode action to the speleothem sightseeing with water vapor. the existence of lamp - light offered a good chance for the lightloving plant to grow up, thus a lot of bryophyte covered the speleothem sightseeing
洞穴升溫、燈光的烘烤及空氣的對流致使洞穴濕度或局部濕度降低，使景觀產生乾裂、風化；氣流帶入的洞外酸性氣體及高濃度co _ 2在高濕的條件下，結合水汽對洞穴景觀產生酸侵蝕作用；燈光的存在為燈光植物生長提供了條件，使大量的苔蘚類植物生長于鐘乳類景觀的表面；洞外大氣粉塵的進入，給洞穴帶來了非常嚴重的破壞，粉塵在洞內高濕的環境下大量沉降，附著于鐘乳類景觀的表面，致使受污染面發黑，毫無光澤。Especially, atmospheric deposition ( dry and wet ), emissions of mercury from soil, bioremediation in situ for controlling mercury pollution are emphasized
其中重點介紹了大氣汞的干濕沉降、土壤汞的釋放及生物修復治理土壤汞污染。From the research results, we can see that the initial reason, which leads to the degradation of xuanwu lake ecosystem, is pollution. pollution makes the water and sediments hypertrphiation, increases the opacity of water, and decreases the oxygen in water, so the wetland higher plant communities decrease or disappear. the wetland ecosystem loses the balance, while the biodiversity also decreases
研究結果表明，引起玄武湖濕地生態系統功能退化的初始原因是嚴重的環境污染問題，污染加劇了水體及沉積物中的營養鹽含量，增加了水體的渾濁度，降低了水體中的氧含量，從而導致濕地高等植物群落減少乃至消失，盡而引起濕地生物多樣性下降、生態系統失去平衡。The collapsible loess is often met during the construction of the high - grade highway in the loess area, and the main failure is the uneven subsidence of the roadbed and the culvert, which affects the safe usage of the roadbed and the culvert, etc. directed against this, based on the chankou - lanzhou freeway construction, the paper analyzes the application of the composite ground formed by lime - soil pile under the bridge and designs the project, discusses the rules of the contact pressure, the stress ratio of the pile and the soil, compares the p - s curves of one pile, the composite ground formed by one pile and the composite ground formed by two piles based on the in - situ plate loading test, evaluates the bearing capacity of the composite ground of the project
黃土地區的高等級公路建設中經常遇到濕陷性黃土問題，其病害類型主要是地基土受水浸濕后引起路基、橋臺、涵洞等的不均勻沉降，直接影響路基、構造物等的正常使用。針對此問題，本文依託甘肅讒口至蘭州柳溝河高速公路建設工程，對橋基灰土樁復合地基應用的可行性進行了深入分析，根據具體工程進行了合理的設計與計算，並配合現場靜載荷試驗及壓力盒實測數據，探討了基底應力分佈規律，樁土應力比，變形模量的變化關系，對比分析了單樁、單樁復合和雙樁復合的p ? s關系，對橋基灰土樁復合地基承載力進行了整體評價。The formation and evolution of the sequence stratigraphy of the yanchang formation are governed by slow tectonic subsidence, warm humid climates, sediment supply and lake - level fluctuations
延長組層序地層的形成與演化主要受控于當時緩慢的構造沉降、溫濕氣候、陸源碎屑物源供給及湖平面升降等地質因素。This paper presents the mechanism research on the decontamination of air pollution by plants in recent years, mainly including the following : absorption and sorption of stoma and cuticle on leaf surface, plant metabolism and enzyme redox, and degradation by plant in combination with bacteria in root
摘要介紹了植物去除空氣污染物的研究現狀及機理，主要包括：通過葉表面的氣孔和表皮吸收、吸附；植物體內代謝或者分泌酶催化氧化還原進人體內的污染物；通過植物聯合根系微生物降解由於干濕沉降進人土壤或者水體中的污染物等。The climate of this period is almost as warm and wet as the stage 5e of the last interglacial. the mean temperature is 2 - 4 c higher and the precipitation is much larger than that of the today, the holocene which we live in. while in the climatic records of deep ocean, antarctic and greenland ice - core, marine isotope stage ( mis ) 3 is a weakly warm period, though a little warmer than marine isotope stage ( mis ) 2 and marine isotope stage ( mis ) 4, evidently colder than the last interglacial and holocene favorable period
末次冰期中期，即深海氧同位素第3階段的氣候在我國，尤其是青藏高原地區表現出明顯不同於深海沉積物和極地冰芯記錄的特徵：青藏高原古里雅冰芯的~ （ 18 ） o曲線表明3階段存在特強夏季風事件，其氣溫和降水接近於末次間冰期5e階段，超過全新世，其暖濕程度已經達到間冰期的程度；而深海氧同位素3階段在深海、南極、格陵蘭冰芯的氧同位素記錄中均為弱暖期，雖較2階段、 4階段溫暖，但顯著低於全新世大暖期和末次間冰期。Due to the range of human uses made of the watercatchment area adjacent to the great barrier reef some 400of the 3000 reefs are within a risk zone where water qualityhas declined owing to sediment and chemical runofffrom farming, and to loss of coastal wetlands which are anatural filter
由於人們將毗鄰「大堡礁」的集水處用於多種目的，在3000個礁地中有大約400個處在一個危險地帶，那裡的水質因農耕排放物中的沉澱物和化學排放物以及擔當著天然過濾器作用的海岸濕地的流失而出現了下降。Finally, two examples were used to analyse the influence of cycles of drying and wetting on subgrade sedimentation and slope stability of expansive soils, the conclusion is given that the influence of cycles of drying and wetting on strength and deformation must be considered to the foundation or structures which consists of expansive soils
最後我們採用兩個算例分別計算了干濕循環對非飽和膨脹土路基沉降以及邊坡穩定的影響，通過計算得出了在以非飽和膨脹土作為構築物基礎或構築物時，應認真考慮干濕循環對其強度和變形特性降低的影響的結論。分享友人
