  1. There is a range of applied force over which the regression rate remains constant.

    施加的力有一個范圍，在這個范圍內遞減率保持不變。
  2. In view of the fact that the genetic algorithm of stochastic programming based on random simulated technology has succeed greatly, this paper points out that changing parameters of genetic algorithm can obtain a sequence of optimum values of goal function. taking these genetic algorithm values as sampling data, we can get fitting optimum function by using multivariate spline regression and get the lipschitzs constant of the fitting optimum function. so for any chance constrained programming problem, we can get its interval estimate

    鑒于基於隨機模擬技術的遺傳演算法在求解隨機規劃問題上的優越性，本文指出，改變遺傳演算法的參數條件，在此基礎上求得機會約束規劃的若干個最優值，以這些最優值為樣本點，利用多元樣條回歸，擬合得到最優值函數，進而求出最優值函數的lipschitzs常數，從而對于任一機會約束規劃問題，都可以得到它的一個區間估計。
  3. 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。
  4. On the basis of detailed investigation concerning the constant changes and the characteristic of farmers " incomes of ningxia from the year 1978 to 2002, as well as a deep analysis of reasons about slowly - growth of farmers " income and the facts which effect the increasing of farmers " income by using the date and regression analysis, this thesis holds a view that there are many facts that cause the difficult growth of farmers " incomes, we must give prominence to the principal contradiction, for examples, adjusting agricultural structure, transferring surplus labor forces in rural areas, developing second and third industry, improving farmers " quality, reducing farmers " burdens, and so on. this paper consists of five sectors : section one : describing the feature of farmers " income change of ningxia

    第四部分，在分析寧夏農民收入變化的基本特徵以及影響農民收入增長的主要因素的基礎上，提出了當前農民增收面臨的主要矛盾，即：糧食等主要農產品的供求矛盾、小生產與大市場的矛盾、勞動力的充分供給與就業能力不足的矛盾、城鄉二元經濟結構的矛盾；農產品價格的提高對增加農民收入的作用越來越小、農業生產結構調整滯後於食品消費結構的變化，農民增產不增收、農村滯留的勞動力越來越多，難以實現規模經營、鄉鎮企業吸納農村剩餘勞動力的能力下降，使農民非農業收入減少。
