  1. In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor

    針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。
  2.

    分析中可以發現，中心差分方法， newmark中點加速度方法、 z變換方法及duhamel逐步積分法在精度范圍內其計算相位是沒有畸變的，中國地震局工程力學研究所頃土學位論文一但是中心差分方法， newmark中點加速度方法隨著采樣間隔及系統自振頻率的增大，系統的固有自振周期被改變，其傳遞函數的共振區域與理論傳遞函數的共振區域會發生分離。
  3. Objective : to analyze the data of the permanent teeth caries and treatment needs of six age groups people in beijing with statistical methods which came from the second national oral health survey of china in 1995. method : the total sample of 12792 ( 8520 urban, 4272 rural ) for 6 age groups ( 5, 12, 15, 18, 35 - 44, 65 - 74 - year - old ) were examined. the diagnostic criteria recommended by the world health organization were used in this study ( oral health survey basic methods third edition, 1987 ). result : the dmf and dmft incidence of six age group in the urban was higher than that in the rural on the whole. the dental caries level of 12 - year - olds was very low. f percentage of 12 - year - olds was 15. 42 % ( urban ) and 3. 23 % ( rural ). the current situation of chinese dental care cannot meet the who objectives for the year 2000. conclusion : it pointed out that we should emphasize oral health education and enhance the consciousness of health care. since the treatments of caries became more complicated with the age, we should perform the primary oral health care in the early stage

    目的:本文對1995年第二次全國口腔健康流行病學調查中，北京地區六個年齡組人群的恆牙患齲及治療需要情況進行統計學分析.方法:採用整群抽樣方法，對北京市六個年齡組的城鄉人群12792人（城市8520人，農村4272人）進行了口腔檢查，診斷標準根據世界衛生組織1987年第三版一書.結果:各年齡組的患齲率及齲均基本是城市高於農村， 12歲年齡組的患齲情況處于很低水平， 12歲年齡組恆牙充填率為15 . 42 （城）和3 . 23 （鄉） ，結論:本結果離2000年目標有一定差距，提示我們應加強口腔健康教育，提高居民口腔保健意識.另外，隨年齡的增長牙齒治療的復雜程度逐漸增高，因此，應在人群中開展初級口腔衛生保健，做到早發現，早診斷，早治療
  4. The sense of this work is to gain a further understanding of helium in the two metals. on the diffusion of helium - 3 in two spherical shell samples made of 21 - 6 - 9 type of stainless steel, during the storage of tritium at the pressure of 6. 13mpa for about 4 and 6 years at room temperature and later exposed to air for another 3 and 1 year. first, a calculation based on the analytical and numerical method to the diffusion and decay theories was developed to evaluate the concentration distribution of helium - 3 by tritium diffusion and decay in the samples

    在不銹鋼氚衰變~ 3he的擴散行為研究中，建立了氚和~ 3he濃度分佈的解析解和數值計算方法，以評估充氚不銹鋼球形容器壁中氚衰變~ 3he的宏觀濃度分佈，同時還用數值計算方法以求解氚和~ 3he的多步擴散行為；對樣品表面逐層蝕刻、同時收集釋放的~ 3he進行分析，分別實測了經室溫條件下在6 . 13mpa高壓氚中貯存4年和6年、空氣中存放3年和1年的兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he濃度分佈；結果表明：由於he在金屬中的不可容性， he原子偏聚于不銹鋼表面以及內部的局部區域，在整體趨勢上， ~ 3he分佈與計算結果相一致，根據理論計算，兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he到達的深度分別為350 m及500 m 。
