多重zipf維數模型不僅可以有效地統一中心地的等級階梯與位序-規模法則反映的連續分佈，而且可以揭示城市體系演化的更多信息和隱含法則。以美國城市體系1998年的數據為實證對象，給出了城市規模分佈的多分維 -
The main body can be summarized as the following five sections : this paper firstly creatively builds the yield curve of our treasury securities by the method of regressive interpolation and spline. by the empirical study we can see that the method not only can build a smooth yield curve but also can predict the yield to maturity of any given term on the basis of the practical dealing data on the markets
主體內容可概述為以下五部分：論文首先創造性地把回歸插補法和三次樣條插值法結合起來構造了中國的國債收益率曲線，經過實證分析表明，該方法可以以中國國債市場上的實際交易數據為樣本，既能構造平滑的國債收益率曲線，又能預測任意到期期限的國債收益率。 -

同時考慮國外經驗式的水分滲透特性曲線，確定由外力因素引起的填方路堤內部的水位濕潤線分佈曲線。 -
Based on the discussion on the principle of density - logging, this paper analyses far - gamma gamma rate, near - gamma gamma rate and density - logging curve respectively, and discusses far - gamma gamma rate near - gamma gamma rate and density variation caused by radioactive anomalies, and preliminarily interprets factors that could lead to the variation of density - logging curve of radioactive anomalous layer, thus explaining the reason why density - logging curve changes at the radioactive ore - layer in northern ordos basin, finally, an empirical formula for revising the distortion of density - logging curve has been established
摘要本文概述了密度測井原理，分別對長源距計數率、短源距計數率及密度曲線進行分析，對由於放射性異常引起的長源距計數率、短源距計數率及密度變化情況進行了討論，初步解釋了放射性異常層位密度曲線的變化因素，說明了鄂爾多斯盆地北部地區密度測井曲線在放射性礦段的變化原因。 -
By deep analyzing the tested value of the concrete strength with the rebound method and combining with the inverse regression theory, a rebound strength curve ( empirical formula ) of three - parameter inverse regression is put forward
