In this paper, based on land use maps of 1976, 1988, 2003, which were interpreted from the landsat mss / tm / etm imageries, and the map of main road, with the buffer analysis tool in arcgis 8, we studied the land use and land cover change on the two sides of the main roads in xishuangbanna, then we studied the impact of population density and the topographic factor on road effects. during the study both the comprehensive land use dynamic degree model and the land use degree comprehensive index model are taken into account, we put forward a compensatory model ? “ amendatory comprehensive land use dynamic degree model ”
由於人類活動干擾強度加大，公路效應深度不斷擴展， 1976年為5km ， 1988年為7km ， 2003年達到11km ;受自然、社會條件的影響，不同路段的公路效應存在較大差異，甚至同一路段兩側效應也各不相同。 1976年至2003年，距公路不同距離范圍內的人口密度都在增加，且距離公路越近，人口數量密度越大、增長越快，人口分布有向公路兩側聚集的趨勢。選取人口密度為大、中、小三個樣區分別分析公路效應的范圍表明，人口密度 -
This paper referred to the massive domestic and foreign technical material, elaborated in the sheet forming value simulation theory essential technology in detail, points out when analysis sheet forming question should use the big distortion ball plasticity fem and introduce the application characteristic and the function summarizes of the sheet forming simulation software dynaform. secondly, analyzed the cover forming characteristic, simultaneously introduced the influence cover forming factor in detail : such as ramming direction, the craft addendum surface and the material pressing surface, the radius of convex - concave mold, draw bead, pressure strength, blank size and craft margin and so on. and simulates many typical automobiles cover panel with software : such lateral board, back taillight pedestal and storage cover
其次，分析了覆蓋件成形的特點和要求，同時詳細介紹了影響覆蓋件成形的因素如沖壓方向、工藝補充面和壓料面、凸凹模圓角、拉延筋、壓邊力、坯料尺寸和工藝切口等，並用數值模擬軟體對多個典型的汽車覆蓋件汽車后側圍板、后燈座以及轎車后備箱蓋的沖壓成形情況進行模擬，用模擬結果優化拉延工藝方案，比較了內覆蓋件和外覆蓋件在成形特點和要求的一些異同點，以及常見的起皺、拉裂和回彈、成形不足等缺陷的產生機理和相應對策，重點介紹工藝補充面和壓料面的設計及優化方法，因為拉延是沖壓工藝的關鍵工序，而工藝補充面和壓料面的設計是拉延工序的關鍵，對消除缺陷至關重要。 -
This exceptionally dry month was the main contributing factor of the below - normal annual rainfall. the very dry weather in july was associated with the ridge of high pressure over the pacific being exceptionally strong and extending west to cover south china, bringing a long spell of fine weather to hong kong from late june to late july
這主要是由於二零零三年七月是有紀錄以來最少雨的七月份，只有正常雨量的三分一左右，在六月底至七月底期間一道異常強大的高壓脊由太平洋向西伸展覆蓋中國南部，令香港長時間持續天睛。 -

The equation is y = a ebx, the interrelated coefficients are all larger than 0. 95 ; when the rainfalls are close, the volume of the surface runoff increases with the intensity of rainfall and the volume of the surface runoff is remarkable related with the maximum rain intensities of 30 minutes ; with the effect on rain harvesting acreage, the cover rate of the plants, the gradient, and the average soil thickness, the cover rate of the plants and the average soil thickness are the important factors which can affect the volume of rain harvesting. and the average soil thickness is the dominant factor. in order to get good result, we must choice the slope which the cover rate of the plants is low and the average soil thickness is thin, meanwhile increase the rain - harvesting acreage
太行山片麻巖區坡面集雨規律及集雨技術：集雨量與降雨量呈顯著正相關，並且在降雨量大於17 . 6mm時，集雨量隨降雨量的增加呈指數形式增加，擬合方程為y = ae ~ （ bx ） ，相關系數均大於0 . 95 ；降雨量相近的條件下，徑流量隨降雨強度的增大而增大，且在片麻巖山地， 30min最大雨強是影響產流的關鍵因子；在集雨面積、植被覆蓋度、坡度以及平均土層厚度等因素的共同影響下，植被覆蓋度和平均土層厚度是影響集雨量多少的主要因素，其中平均土層厚度是主導因素；而要想取得良好的集雨效果，必須在選擇植被覆蓋度低、坡面土層厚度薄的坡面的同時，加大集雨面積。 -

Authors used auto - correlation method and took longhua area, shenzhen city, as working area to study the spatial structure characteristics of landscape pattern and their contributing factors. the results indicated that all the landscape structure variables, which were used in the analysis process, expressed good structure features. it means that the landscape pattern of working area was formed by some kinds of driving forces which could not only cover the whole area, but also had good continuity. detailed analysis resulted that the elevation differences were only the background impact factor of the landscape spatial pattern, but the intensive artificial landscape reforming of the fast urbanization process was the main contributing factor, which made the significant differences of landscape structure between 1988 and 1996. since 1990, the landscape of working area has gradually changed to a landscape dominated by human impact
利用空間自相關分析方法，以深圳市華地區為例，對快速城市化景觀的空間結構特徵及其成因進行了研究。參與分析的景觀結構變量均表現出較好的結構性，表明該地區景觀是在一種既可以覆蓋全區，又具有良好連續性的驅動機製作用下形成的。進一步詳細分析結果表明，工作區內的地形條件差異是景觀空間分佈格局成因的背景性因素，而快速城市化過程中人類活動的強烈改造作用，是導致1988年和1996年景觀結構特徵發生顯著差異的根本性影響因素。 -
