As long as crude oils are produced offshore and transported across the seas by ships or pipelines, there is a risk of oil spills with the potential to cause significant environmental damage. the " exxon valdez " incident in alaska, and other oil spills in recent years, have demonstrated high risk and damage to the local economics and environment caused by oil pollution
隨著對海洋石油資源的大力開發和全球海上石油運輸量的持續增長,溢油事故發生的頻率越來越高,溢油規模也越來越大,溢油事故的發生,不但給當地漁業、水產養殖業、旅遊業等造成經濟損失,也嚴重損害了海洋以及海岸的自然環境和生態環境。Among them distributing with the traffic of average rate of increase law calculation flow of passengers capacity ; the flow of passengers is brought out in model law calculation with gravity ; constructing the rate sharing responsibility for building model calculation according to transportation resistance shifts the flow of passengers ; think over time value when the flow of passengers is brought out in the calculation
以膠濟鐵路提速改造為例,就構造的客運量預測模型作了應用研究。其中以平均增長率法計算客流量的交通分佈;以重力模型法計算誘發客流;依據運輸阻力構建的分擔率模型計算轉移客流;在計算誘發客流時考慮了時間價值。Quantified analysis of economical growth efficiency of rail transport enterprises
鐵路運輸企業經濟增長效率的量化分析In this thesis, we used the q - switched nd : yag laser pulse focused by lens to pump the cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, with the pump laser pulse duration and energy of 30ns and 50 mj separately, and got the laser pulse with center wavelength, pulse duration and energy of 1. 22 m, 8. 2 ns and 10 mj on the best work condition. on the base of zhangguowei s approximation about gain - switching and the parameter of cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, we calculated the time characteristics of cr ~ ( 4 + ) : mg _ 2sio _ 4 laser pulse with rate equation by numerical method, obtained the conclusion that the laser pulse duration is only related to the pump energy and cavity length : the larger the pump energy is, the narrower the pulse duration is ; the longer the cavity is, the wider the
本論文採用調qnd : yag脈沖激光通過透鏡聚焦后縱向抽運cr ~ ( 4 + ) : mg _ 2sio _ 4晶體,抽運光脈沖寬度為30ns 、能量為50mj ,在較佳工作條件下得到了中心波長為1 . 22 m 、脈寬為8 . 2ns 、能量為10mj的激光脈沖;並在張國威分析增益開關時間特性的近似法基礎上,結合實際的cr ~ ( 4 + ) : mg _ 2sio _ 4激光器的相關參數,從速率方程出發,用數值計算的方法更為精確的模擬了cr ~ ( 4 + ) : mg _ 2sio _ 4激光器輸出激光脈沖的時間特性,得出了激光脈寬只與抽運能量、腔長有關的結論,即抽運能量愈大,脈寬越窄;腔長越長,脈寬則愈寬。分享友人
