解釋
經驗常數-
Through the numerical calculation for improved soil layers, there is an economical and reasonable improved zone whose depth is a constant but whose width is decided by the controlling residual deformation of subway structure. and a empirical formula for the subway residual deformation is given which can consider the improvement depth and width
通過對加固后的地基進行多次有效應力模擬，發現南京市地鐵地基合理的加固深度基本上保持不變，而合理的加固寬度則可由控制震后殘余變形來決定，並給出了計算加固后的地鐵隧道震后殘余位移經驗公式。 -
According to the problem that the recovery rate is traditional treated as a constant or an independent stochastic variable by the classical credit risk pricing and management model, and problem that the negative correlation between the default probability and recovery rate is always neglected, this dissertation gets the exponential and logarithm regression models of default probablilty and recovery rate based on some empirical researches, and improves on several broadly applied credit risk models, such as structural hazard rate model, affine structure model, convertible bond pricing model and credit metrics model, and introduce the negative correlation between
針對傳統的信用風險定價模型及信用風險管理模型將違約回收率看成是一個外生的常數或是一個獨立的隨機變量，而忽略回收率和違約概率之間的負相關性這一問題，本文應用相關實證研究得到了違約概率和回收率的指數和對數回歸模型，並對應用非常廣泛的結構化風險率模型、仿射結構模型、可轉換債券定價模型和creditmetrics模型進行了改進和拓展，在新模型中應用指數和對數函數引入了這兩個變量之間的負相關性。 -
A calculation comparison on the pipeline network system consisting of pipe sections of short length is made herein with three calculation methods respectively, i. e. neglecting the local energy loss at junctions ; adopting constant local energy loss coefficients and the semi - empirical relationships based on experimental data related to the flow conditions, from which the calculated results for the flow rates of the pipe sections are largely deviated
文中分別應用三種計算方法，即忽略結點處局部能量損失、採用恆定不變的結點局部能量損失系數，以及根據試驗成果所得的與水流條件有關的半經驗公式，針對短管段構成的管網系統進行了計算比較，管段流量的計算結果相差很大。 -
We will give the asymptotic normality and consistency of mle for multivariate model with constant correlation introduced by bollerslev ( 1990 ). 3. moreover we will introduce the agarch model with non - normal distribution and have empirical study shows that the model suggested is feasible
在多維的情形下，著重研究bollerslev （ 1990 ）提出的常數相關的多維garch模型的極大似然估計（ mle ）的漸近正態性和相合性。
