( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。After the breakdown of the system of bretton woods, the practice of frequent international capital flowing impels the development of the theory of decided exchange rate. this theory is from the theory of purchasing power parity, the theory of interest rate parity, the theory of international income and expenses to the theory of asset market. but, at present, the theory of cost in exchanging specially used in our country is applicable
布雷頓森林體系解體以來，國際間資本頻繁流動的實踐推動了匯率決定理論的發展，匯率決定理論也從購買力平價說、利率平價說、國際收支說走向資產市場說，但是我國特有的換匯成本說在當前還有一定的適用性，隨著國內外金融市場間的聯系漸趨緊密，利率平價說對於人民幣匯率變動的解釋力也會逐漸增強。According to the practical geological model of slope, by means of the finite element analysis, from the constitutive equations of the elastoplasticity and the viscoelasticity - viscoplasticity, the process and mechanism for progressive failure of the locked segment of rockmass are quantitatively revealed and simulated during the rupture, deformation, destruction, and failure of highsteep slope rockmass, and the dynamics driving the motion of rocky landslide with violent starting velocity by high pressure water flow is dealed with
根據邊坡實際地質模型，基於彈塑性與粘彈-粘塑性理論的本構方程，通過有限元模擬分析，定量地揭示和模擬再現了高邊坡巖體破裂、變形、破壞及失穩前後鎖固段巖體漸進性破壞的機制和過程，探討了高壓水流作用下滑坡啟程劇動的破壞機理。Heterojunctions : conduction normal to junction : i - v models and characteristics. theory of graded layers ; creation of internal carrier - specific fields
垂直於接面的電流傳導：電流-電壓模型與特性。漸變層理論；內部載子規?電場的產生。This paper explains the basic knowledge and basic theories of national debt, gives the calculating formula of construe and stochastic construe separately. combing with the monadic regression model, the paper analyses the development of issuing scale of national debt of our government annually, studies the evolvement of scale of national debt and its relevant policies, and analysis the experience indexes measuring scale of national debt which is prevail in the world quantificationally. comparing with western developed countries further, based on that, there is a conclusion in this paper, the government issuing scales of national debt is appropriate at present, but it is impossible to increase the issuing scale
本文闡述了國債的基本知識和基本理論，用數學分析和隨機分析的方法分別給出了債券的收益率和債券定價的計算公式，結合國債規模的一元回歸模型，仔細分析了我國政府年度舉債規模的發展變化，研究我國國債規模及相關政策的演變，並就國際流行的衡量國債規模的經驗指標進行了定量分析，由此進一步與西方發達國家進行比較，得出我國現階段國債的發行規模是適度的，但進一步增大發行的空間不大，為避免財政風險，發行規模應逐漸減小，積極的財政政策應在適當的時機逐漸淡出。Topography fractal dimension related with process of development of watershed physiognomy and represented degree of watershed development, v ) sediment yield intensity of watershed model reflected erosion characteristic of watershed model in different development phase. simulating experiment indicated that sediment yield intensity took on the trend that they changed from small to big then decreased gradually. the relationship of average sediment transport rate and sediment yield rate per mm rainfall with topography fractal demension is expressed by gaussian model and this model is similar with relationship between volume and surface area
（ 5 ）流域模型產沙強度的變化反映了流域模型在不同發育階段的侵蝕特徵，模擬試驗研究結果表明：在整個流域模型地貌地貌的發育過程中，其產沙強度呈現由小到大，然後又逐漸減小的總體趨勢，流域模型單位降雨產沙率及平均輸沙率與地形分維數表現為gaussian模型關系，其關系形式與結論3中相對體積和表面積之間關系相似，進一步說明了以地形分維數表達地形變化的合理性。Appling p - n graded heterojunction instead of abrupt one is studied deeply in theory, and the conclusion is that it will enhance the current injection ratio, decrease the built - in voltage, improve the quality of the crystal and it will not affect the confinement to the hole
在理論上提出在hb - led器件的dh結構中使用p - n結的漸變異質結替代現行的p - n突變異質結。分析採用異質結漸變方式將增加hb - led的電流注入比，減小內建電勢，改善晶體質量，並且不影響p - n結對空穴的限制。分享友人
