本文根據南黃海中部泥質區和東海中陸架的兩個鉆孔巖芯的古生物、 ams ~ ( 14 ) c測年、淺地層剖面等,參考qc _ 2 、 dz _ 4成果及標準氧同位素曲線探討了黃東海陸架晚第四紀古環境演化、底棲動物群特徵、古氣候、冰後期以來氣候事件、古水團、沉積速率、古水深、沉積物源、海平面平均上升率,討論目前中國東部海平面上升的狀況、溫室效應及海岸帶保護。Since 1979 china has signed a series of international environmental conventions and agreements, including the convention on international trade in endangered species of wild fauna and flora, international convention for the regulation of whaling, vienna convention for the protection of the ozone layer, basel convention on control of transboundary movements of hazardous wastes and their disposal, montreal protocol on substances that deplete the ozone layer ( revised version ), framework convention on climate change, convention on biological diversity, convention on combating desertification, convention on wetlands of international importance especially as waterfowl habitat, and 1972 london convention
中國自1979年起先後簽署了《瀕危野生動植物種國際貿易公約》 、 《國際捕鯨管制公約》 、 《關于保護臭氧層的維也納公約》 、 《關于控制危險廢物越境轉移及其處置的巴賽爾公約》 、 《關于消耗臭氧層物質的蒙特利爾議定書(修訂本) 》 、 《氣候變化框架公約》 、 《生物多樣性公約》 、 《防治荒漠化公約》 、 《關于特別是作為水禽棲息地的國際重要濕地公約》 、 《 1972年倫敦公約》等一系列國際環境公約和議定書。And the environmental investigation agency pins the blame on the widespread use of chlorofluorocarbons cfcs and halons, which wipe out protective ozone in the atmosphere
因此,環境調查署將禍首指向破壞大氣臭氧保護層的氟氯碳化物以及海的大規模地交易買賣。Sige simox : oxygen ions with high dose were implanted into sige grown directly on silicon substrate for the first time, and sige - oi novel structure was formed successfully with additional high temperature annealing ; it has been confirmed that oxygen implantation with 45kev, 3 1017cm - 2 and annealing at 12500c in ar + 5 % o2 for 5 hours, are fit for the formation of sige - oi structure ; ge loss during the high temperature annealing has been observed, which is originated from ge volatility and ge diffusion ; it has been proposed to use nanoporous layer induced by h + / he + implantation to surppress ge diffusion and to use surface oxidation to overcome the upper limit of sige simox. sige smart - cut : hydrogen ions were implanted into sige material and followed by high temperature process ( 4000c to 7000c ) ; blistering study was done and suggested the possibility of sige layer transfer by smart - cut technology ; it is concluded that the bubble formation is easier in sige than in si, and the strain in sige / si and the difference of binding energy in sige and in si could possibly contribute to this effect. behavior of sige / si implanted with hydrogen : gave a detailed study on sige implanted by beamline or phi hydrogen implantation ; it has been found that great strain is introduced into sige by hydrogen implantation and this strain could be alleviated by high temperature annealing ; both for conditional beamline implantation and piii hydrogen implantation, 600 is appropriate for the post - implantation treatment
Sige - simox工藝方面:首次採用硅( 100 )襯底上直接外延的100nm厚sige的樣品中注入高劑量的o離子,通過退火處理成功制備了sige - oi新結構,即sige - simox工藝,證實了以45kev注入3 10 ~ ( 17 ) 7cm ~ ( - 2 )劑量的氧離子,隨后在氧化層的保護下經1250 , ar + 5 o _ 2氣氛的高溫退火( 5小時)過程,可以制備出sige - oi新型材料;實驗中觀察到退火過程中的ge損失現象,分析了其原因是ge揮發( ge通過表面氧化層以geo揮發性物質的形式進入退火氣氛)和ge擴散( ge穿過離子注入形成的氧化埋層而進入si襯底中) ,其中ge擴散是主要原因;根據實驗結果及實驗中出現的問題,對下一步工作提出兩個改進的方案:一是通過在si襯底中注入適量h ~ + / he ~ +形成納米孔層來阻斷ge擴散通路,二是可以通過控製表面氧化來調節安止額士淤丈撈要表面sige層中的ge組分,從而部分解決sigeIr - ta - ti metal oxide coated titanium anodes of variable composition were prepared by thermal decomposition. their micro morphorogies and electrochemical properties were characterized by scanning electron microscope, open circuit potential, cyclic voltammetry, consumption rate measurements and accelerated life test. the sem results indicated that all coatings were of a porous and cracked - mud microstructure influenced greatly by the composition of coatings. the electrochemical measurements showed that the ir - ta - ti ternary oxide - coated anodes exhibited excellent electrochemical activity and electrochemical stability in both acidic media and seawater which were affected by the composition and microstructure of the coatings. owing to good corrosion resistance and low consumption rate in seawater, metal oxde coated anodes belong to insoluble material, and can be potentially applid in impressed current cathodic protection systems as an anode
