This thesis also researches and develops some theories about the efficiency of financial supervision . it researches the changed track of financial supervision costs and yields that variate as the financial supervision degree changes . then it arrives at the most benefit point of financial supervisi on degree 本文还对财政监督效益的相关理论进行了研究和创新，研究了财政监督收益与成本随监督程度变化而变化的轨迹，进而得出最优的财政监督程度点。
The paper focuses on how to evaluate the competitiveness of the four listed banks in china and introduces var ( value at risk ) , which provides an easy way of measuring and managing financial risk , into existing competitiveness evaluation system . then we make comprehensive evaluation of the four banks ’ competitiveness through factor analysis , which is a branch of multi - variate statistical analysis 本文以基于var的上市商业银行竞争力评价体系研究为题，以我国四家上市银行为实证研究对象，将风险价值( var )引入传统的竞争力评价指标体系中，然后利用因子分析法对原始数据进行处理，得到相关主因子，进而构建出上市银行竞争力的综合评价新模型。
Due to the fact that the models for resource characteristics vary a lot , this paper will first utilize quantified model and cluster analysis method from multi - variate analysis methods to conduct classification , then quantified model will be used to examine the extent of impact that can be exerted by conditions of recreational site to recreational demand 由于资源特性之种类繁多，因此本文先利用多变量分析方法中之数量化模型及群落分析法进行分类，以?解各游憩据点类型之特性，再透过数量化模型探讨游憩据点条件对游憩需求之影响程度。
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 摘要从福建省第5次森林资源一类调查落在闽江流域的样地中抽取马尾松林样地130个，以rs可提取因子及样地林分立地条件因子为可选变量，利用3倍标准差法进行异常数据的筛选，对林分立地条件定性因子进行数量化处理，通过逐步回归构建闽江流域马尾松林分蓄积量估测模型，研究结果所构建的蓄积量估测模型的相关系数为0 . 735 。
What the practical problems is often gotten is a single variable time series which has a time interval of t , reflect by a lot of interactive physics factor , containing the mark of all variates participating in movement , traditional time series analysis is to analyse going from this array to the form directly it ' s time develops , one dimension analysis loses useful information , the characteristics of phase space reconstruction method is to construct one dimension scalar quantity to high dimension vector , prop the geometry space of the state , show all dynamical information of system in phase space . the characteristic that just constructs again according to the phase space in this text , analyse the time series of responding , use the relevant knowledge of symbol dynamics and reconstruct phase space , put forward a kind of relation degree analysis method of the systematic mathematics model which has theory basis , so reach the correction of calculation mathematics model , make it accord with the actual systematic state 实际问题中常常得到的是一个时间间隔为t的单变量的时间序列，它是许多物理因子相互作用的综合反映，蕴藏着参与运动的全部变量的痕迹，传统的时序分析是直接从这个序列去形式地分析它的时间演变，一维分析必然丧失许多有用信息，相空间重构方法的特点是把一维标量数据构造成高维矢量，支起状态的几何空间，在相空间中展示系统全部动力信息。本文正是根据相空间重构的特点，对响应时间序列进行分析，利用符号动力学、重构相空间等方法，提出一种有理论依据的系统数学模型关联度分析方法，从而达到修正计算数学模型，使其更符合实际系统状态的目的。
Abstract : based on the fundamental principle of hypothesis strain equivalence , itwas investigated a physical concept of high strength concrete at minus temperature ( hscmt ) freezing damage parameter , the elastic modulus of frost concrete with anti freeziug admixture and without antifreezing admixture built and it was analyzed their variate process and the condition adaptated . it is purpose to judge hscmt frost failure process 文摘:从应变等效性假说的基本原理出发，研究了负温混凝土冻结损伤参数? ?弹性模量法中受冻后测试的损伤混凝土弹性模量的物理概念，从而分析了掺防冻剂混凝土及不掺防冻剂混凝土受冻后的弹性模量变化过程及其选用该参数的适应性条件，为判断负温高强混凝土材料冻结失效过程提供保证。
