The new method to control birds hazard is put forward by the way of ecological food chain in this article. it has the important value on the construction of new airports and the treatment of birds hazard in the present airports
本研究提出了一種以食物生態鏈方式控制鳥害的新途徑，為我國航空鳥害的防治探索了一條新的途徑，對新機場建設和已有機場鳥撞防治具有重要的參考價值。On the basic of a great of literature reading and research on safety of side impact of the car, according to requirement of ece r95, applied madymo6. 2. 1 software, established simulation model of side impact of the car, researched the relationship between side rigidity of the car and passenger injury in side impact, which showed that during first impact the bigger side rigidity was, the more advantaged protection for the car and passenger in a definite range, and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact. then detailed the substructure model by defining bodies, joints, contact types and contact characteristic, researched some improvement approach for side safety of the car, and then analyses a particular case, that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door, analyzed the influence of passenger injury when the bar fender was fixed on different position, the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar. finally, a set of tests were performed, contrasting the simulation result with the test, analyzed the influence of the side rigidity of the car to passenger injury, which showed the test
本文在對汽車的側面碰撞安全性進行大量文獻閱讀和研究的基礎上，按照歐洲ecer95側面碰撞乘員保護法規的要求，應用多剛體動力學軟體madymo6 . 2 . 1 ，建立了汽車的側面碰撞模擬模型，研究了汽車的側面剛性對乘員損傷的影響，結果表明在「一次碰撞」中，在一定范圍內汽車側面剛性越大，越有利於汽車和乘員的保護，同時得出結論，即在「一次碰撞」過程中人體損傷最嚴重的部位是骨盆;然後通過定義各剛體、鉸鏈、接觸類型以及接觸特性，對該模型進行子結構細化工作，研究了加強汽車側面安全性的若干改進措施，並進行了一個特例分析，即在此模型的車門內外板之間安裝了車門防撞桿，分析了當車門防撞桿安裝在不同位置時對乘員損傷的影響，結果表明防撞桿位於車門裝飾條的高度時，對乘員的損傷較小;最後進行了一組側面碰撞試驗，通過試驗和模擬結果的對比，分析汽車的側面剛性對乘員損傷的影響，表明試驗和模擬結果是一致的，從而證明了模擬模型的有效性以及模擬結果的正確性。What the most important thing is that it discovers a new way to control birds hazard of the native airfields. all kinds of aspects, combining with the safety flying of civil aviation, are studied by consulting the same international researches in the period of one year. the study includes the ecological background of airport environments ( plants, animals in the soil, insects, small beasts, kinds of birds and their numbers, habitat environments, food, etc. ) and the behaviour of birds ( distribution, rules of acting, environmental factors of attracting birds )
研究內容結合民航安全飛行實際，參照國際同類研究，對機場及周圍環境中與發生鳥撞有關的生態學背景（植物、土壤動物、昆蟲、小型獸類，以及鳥的種類及其種群數量、棲息地環境、食物等生態學基本要素）和鳥類行為（鳥類分佈情況、鳥類活動規律及吸引它們的環境因素）進行了一個年周期的全面研究，並依此提出機場鳥類棲息、生活、取食，以及鳥類食物鏈等生態環境控制的生態學防治措施。
