碳粒燃烧的连续膜模型的计算结果和FTIR E-T测温实验结果表明，在实际煤粉火焰条件下，单膜模型和严格的连续膜模型的预报结果相差较大，特别是对着火点及着火后某段区间内的颗粒温度的预报，是仅考虑表面氧化反应C+1/2O〓→CO的单膜模型所无法完成的，这说明了单膜模型存在一定的应用局限性。

The third model is die combination widi concentrating-share model and discount model. Firsdy, we must concentrate state-owned share based on investing cost; secondly, we can evaluate die stock on full-flowing condition by discount model, dien we can get die reasonable price of state-owned share.

3折股贴现模型：该模型其实是折股模型与贴现现金流模型的组合，首先我们要将国有股按投资成本进行缩股，使之与流通股同股，进而实现全流通，然后用自由现金流模型计算全流通条件下股票的内在价值，最后再来推算国有股的价值。

Then the time-dependent resistance models of the timber beam and timber column are calculated in which the empirical formula in China is used for above- ground,exposed timber beam and column and the decay depth model for under-ground timber in Australia is adepted the timber embedding wall.

然后据此推导了彩钢活动房各类构件的腐朽抗力衰减模型，采用国内经验公式推导了抗弯腐朽木梁和地面上木柱的随机时变抗力模型；采用澳大利亚的地下木材的腐朽深度—时间模型，推导了初始抗力为正态分布的随机变量的墙内木柱的随机时变抗压承载力模型，并采用该模型对某历史结构的木梁进行了剩余寿命预测。

Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.

本文在分布式水文模型的基础上，对河南省燕山水库流域洪水入库计算模拟方面作了一些研究：从燕山水库流域的下垫信息开始着手，依据流域的土地使用类型图、土壤分布图确定每个栅格单元的土壤特性和土地利用方式，进行下垫信息的参数化，得到单元模型所需的参数值；为了提取地形信息，本文通过对流域地形图海量数据加载高程值，利用GIS软件自动生成流域内的数字高程模型，提取了流域水文模型所需要的库容曲线；通过栅格自动划分，提取栅格单元的高程、坡度、栅格流向、流域边界、虚拟河网、流量积累、等时流线面积分布等分布式水文模型的流域特征。

In the model solution method's choice, according to the mix integer model's characteristic, the paper proposed to divide the model solution into two parts. The linear segment used the transportation plan method to solve and the mis alignment part used the implicit enumeration to solve. Finally the paper proved the model's feasibility through the example to solve the location-selection for the distribution center and obtained the quite satisfactory the location-selection result.

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。
