  1. With the rapid development of the scientific technology and the acceleration of the steps of urbanization and industrialization, the environment disruption to the natural sources done by human beings gets more and more serious. since the twentieth century, the environment problems have become more and more obvious, and the environmental crimes as well as the environmental public nuisances have happened continually, all of which have greatly threatened the human lives, the security of property, and even the social and economic development

    本文以犯罪學為視角，通過描述的方法對反國際環境犯罪的法律對策、社會對策的現狀進行了列舉，然後運用列舉、對比、概括等研究方法對打擊和預防國際環境犯罪的立法現狀、執法現狀和非法律層面的合作現狀進行了評析，並提出其中存在的問題和解決的建議。
  2. Layout is an important part of the sea reclamation works, which consists of for kinds of rational layout of the exploitation of the embanked area, the irrigation and drainage works, the sea exploitation work schedule and the silt acceleration work schedule. not only are the four kind layout works interrelated and interrestricted, but also they come down to many natural and society factors

    圍海工程規劃是圍海工程重要組成部分，圍海規劃由圍區土地合理開發利用規劃、圍區排灌工程規劃、圍塗開發進度規劃和圍塗的促淤進度規劃組成，這四部分的內容不僅相互聯系又相互制約，而且還涉及到眾多的自然因素和社會因素。
  3. ( 三 ) under the dynamic load of the explosion, the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0. 3hz, the acceleration of the slopes top gets the maximum ; so 0. 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform, when the relative altitude is up to 45m, the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m, the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration, at the top of the slope, the acceleration of horizon become larger and larger ; at the middle part of the slope, it becomes smaller ; ( 4 ) when the explosion velocity of is much little, the shallow part destruction is the primary deformation of the slope

    （三）採用模態疊加法針對爆破動力作用，進行邊坡的動力響應分析，得出了以下結論： （ 1 ）振動頻率為0 . 3hz時，坡面頂部水平向加速度峰值最大；綜合考慮，可認為該邊坡的自振頻率為0 . 3hz左右； （ 2 ）地形對爆破地振動存在放大作用，研究剖面的坡面，水平向加速度及位移在地形相對高差45米左右最大，而後隨相對高差的增高而減小，相對高差為100米時，水平向位移及加速度絕對值均大於坡腳； （ 3 ）強迫振動段，水平向加速度值隨時間變化的規律為：坡頂節點總的變化趨勢是越來越大，而坡體中部節點的變化趨勢是越來越小； （ 4 ）當爆破振速較小時，變形破壞的形式表現為坡頂表面滑塌型。
  4. The contributions to dynamic responses from the modes with low natural frequency are also discussed. the new expression of the mode - acceleration solution is employed to improve evaluations of the wind - induced response for large roof structures in this paper. in this method, the contributions of those high order models were compensated, and the question of choosing proper modes is avoided

    本論文從模態加速度法的理論出發，把因為採用模態位移法而捨去的高階模態對響應的貢獻，通過剩餘柔度陣的方法進行補償，從而避免了繁瑣的高階模態分析過程和如何選擇的問題。
