外來生物對鳥類的影響主要表現在以下幾方面： （ 1 ）外來哺乳動物對成鳥、幼鳥或鳥卵的捕食作用； （ 2 ）外來鳥類與本地鳥類競爭棲息地和食物資源，與當地的近緣種雜交而造成基因流失； （ 3 ）外來無脊椎動物改變本地鳥類的棲息環境和食物狀況，甚至直接捕食本地鳥類； （ 4 ）外來植物入侵改變入侵地的植物群落組成和結構，造成本地鳥類的棲息地喪失或破碎化，並通過改變入侵地生態系統的食物鏈結構而對高營養級的鳥類產生影響。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。In all of alternative technology, reverse stirling - cycle has a good foreground : because of the refrigerant being used in stirling - cycle were acquired from nature, it has less impaction to surroundings, in the other hand, the reverse stirling - cycle has the same cop with anti - cannot cycle in the same temperature bound. at last, the author analyzing the reverse stirling cycle, and put forward the thought of applying this technology in air - conditioning
對現有替代技術進行了總體評估，現有替代技術中，用逆斯特林循環來替代蒸汽壓縮式製冷循環很有前景：其所用製冷工質全來自自然界，對環境的破壞作用很小；另外，從逆斯特林循環本身來講，它和同溫限下的逆向卡諾循環有相同的效率。Several important conclusions are gained by the analysis of push - over method and quasi - static reversal load pattern to a reinforced concrete structure : under the two earthquakes, the responses of structure are more serious than the responses under single earthquake, by the conclusion, it is not rationality that structure ' s earthquake damage prediction under single earthquake ; the main - after earthquake action is different from fore - main earthquake action under the same earthquake magnitude combination ; the push - over analysis to the structure is convenient and utility, it also reflects the response and performance of structure under the earthquake, so the method ' s development future is wide. based on the research of the former scholars, some means of structure resisting earthquake are introduced in the last part of this thesis, and the result of earthquake damage prediction for the planning area of quanzhou city is given
通過對一鋼筋混凝土結構進行push - over分析與擬靜力循環往復加載分析，得到了一些重要結論：在兩次地震動作用下，結構物的反應比僅考慮一次地震動作用時的反應要嚴重的多，從而說明傳統上僅僅考慮一次地震動作用的建築物震害預測是不合理的：即使在同震級組合的兩次地震作用下，前震主震型、主震餘震型地震對結構物產生的破壞作用也是不盡相同的；對結構物進行靜力彈塑性分析的方法（ push - over方法）簡便實用，並能較準確地反映大震下結構的一般性能和反應，再一次的證明了該方法具有廣闊的發展前景；根據前人的研究成果，在本文的最後，簡單的介紹了一些結構物抵禦多次地震破壞作用的方法，並給出了泉州市規劃區內鋼筋混凝土框架結構群體震害預測的結果。分享友人
