As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china, more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ). based on the investigation of natural resource and agricultural distribution, the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied, and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis. according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001, the concentrations of toxic substance and heavy metal were under the monitoring limit, but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir
本文調查了千島湖流域的自然資源和農業生產情況，研究了典型坡地降雨徑流中的氮、磷污染物的輸出規律，利用annagnps模型估算流域農業非點源污染物輸入負荷，並在千島湖內設點采樣，對水質理化指標和浮游植物群落進行系統的研究，得出以下結論： 1989 2001年間的水環境常規監測資料統計分析表明，有毒物質和重金屬濃度長期在監測下限內， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均濃度均符合類標準，但湖泊水庫特定項目tn和tp濃度分別為超類和類，呈嚴重超標狀況，湖區主要污染因子是將導致富營養化的物質tn和tp 。 -
At present, the study of the fire safety evacuation in the world mainly focus on : ( 1 ) the importance of the model of egress and the ability of modeling predict a obvious tendency of the study is that there will be more behavior details included in the model in the future ; ( 2 ) the influence of the smoke and its toxicity to people which focus on the study of the influence of toxic gases such as carbon monoxide to people who exposed in fire, the test of the visibility of directional and exit signs, the behavior of the occupants in fire and the time they response to the fire ; ( 3 ) the application of the evacuation model in fire safety design, the constitute of performance - based code and building evaluating the purpose of the study of people ' s evacuation is to improve the fire safety design and cut down the number of casualties
人的生命是寶貴的，因此，世界各國的消防科研主要以生命安全為主，重點研究火災中人員的安全疏散，並提出新的性能化防火設計和性能化防火設計規范，從建築設計入手而保證建築防火設計的可靠性和建築物的火災安全性。目前，國際上對火災安全疏散的研究主要集中在以下方面： （ 1 ）疏散模型的開發和模型預測能力的改進疏散模型方面的研究一個明顯的趨勢就是未來的模型將包含更多的行為細節，注重人的行為的因素。 （ 2 ）火災中人員反應及毒性和煙的影響這一研究主要集中在一氧化碳等有毒氣體對暴露在火場中人員的影響，疏散指示標志的可見度測試，以及火災中人員的行為和對火災的反應等方面的研究。 -
Five different coating materials and four different toxic organic vapors ( methanol, 1, 2 - dichloroethane, benzene and cyclohexane ) have been selected as detective model to examine the feasibility of this instrument
選擇了5種不同極性的敏感膜和4種有毒氣體（甲醇、 1 ， 2一二氯乙烷、苯、環己烷）作為模板檢測物，考察了這個裝置的實用性。
