The impacts of soil and water conservation on river flow and soil - hydrology of jia - lu - he, tu - wei - he, pian - guan - he and qiu - shui - he catchments have been analyzed by the simulation and on - spot measuring methods according to data of during 1950 ' s to 1990 ' s. the selected catchments of the above four all are in the key area of soil and water conservation on the loess pleatu. the main results are as follows. the trend, reasons and critical year of annual river flow " change have been researched by rank correlation and maximum deviation division
本文以黃土高原水土保持重點區的佳蘆河、禿尾河、偏關河和湫水河等四條流域為代表，採用定量與定性、模型模擬與實測對比相結合的方法，系統分析了上世紀50 90年代時段內水土保持對河川徑流及土壤水文的影響，取得主要結果如下：採用秩相關和極差分割等定量評價方法，分析了四條支流徑流量變化趨勢、變化原因及發生明顯變化的臨界年份。Then, this paper introduce a new method of measuring the risk ? ? cohesive value at risk ( cvar ), which is more logical than the var on optimizing the portfolio according to the characteristic of the stock bargaining market of our country, it constructs a corresponding index of liquidity risk of the stock assert of the open - end fund, and by constructing a optimized model in cvar, the liquidity risk of stock assert of the open - end fund is efficiently controlled
接著，本文引入了一種全新測量風險的方法cvar方法，並且根據我國交易市場的特點構造了相應的開放式基金股票組合的流動性風險指標，通過構造cvar調整的投資組合風險優化模型有效的控制了股票資產組合的流動性風險。本文的研究表明: （ 1 ）開放式基金股票組合的流動性風險具有明顯的尾部風險。Use the quantitative analysis tools to valuate use trend extrapolation to forecast sales revenue, linear regression to forecast the future cash flows, tow ? stage discounting cash flow model to valuate the physical assets of zte co. and black ? scholes option pricing model to valuate its growth opportunity or real option. and from the qualitative perspective analyze the reasons for deviations from the enterprise value
用趨勢外推法預測銷售收入，用線性回歸法預測未來現金流量，用兩階段折現現金流量模型評估中興現有資產價值;用布萊克-斯克爾斯期權定價模型預測在競爭條件下中興的增長機會價值;在結尾處，從定性分析的角度研究產生估價偏差的原因。This research established an estimating model of pinus massoniana stand volume with the elements as variates directly obtained from rs and the conditions of stand that were extracted from 130 samples of pinus massoniana stand from the fifth forest resource continuous investigation data in min - jiang watershed and flitered by the thrice standard deviation method and liner regression method and the correlation coefficient is 0. 735 the suitability and precision of the model were tested and regression analysised with data that were extracted from another 30 samples
摘要從福建省第5次森林資源一類調查落在閩江流域的樣地中抽取馬尾松林樣地130個，以rs可提取因子及樣地林分立地條件因子為可選變量，利用3倍標準差法進行異常數據的篩選，對林分立地條件定性因子進行數量化處理，通過逐步回歸構建閩江流域馬尾松林分蓄積量估測模型，研究結果所構建的蓄積量估測模型的相關系數為0 . 735 。The unsteady surface pressures on the rotor blades of a single - stage low - speed axial compressor were measured by means of mounting micro - sensors on the surface the blades
