By comparison with theoretical K value to figure out variance and to find out the main soil character parameter. Using MATLAB software, theory of parameter modification is employed to modify parameters in Normal Equation. Eventually, the proper calculating model of K factor the same with the typical slope soil of highway in Hubei Province, is established.

Owing to the possible measurement error of variance and covariance for Markowitz's M-V model, in the present study, it employs two static models and two dynamic models, which are the sample covariance model, implicit factor mode!, implicit factor GARCH model and full-factor multivariate GARCH model.

基於Markowitz(1952)提出的M-V投资组合模型可能造成变异数及共变异数衡量的偏误，因此，本文以样本共变异数模型、内含因素模型等两我种静态模型，并参酌Alexander and Leigh(1997)的内含因子GARCH模型与Vrontos et al。

This paper reviews the processes in glacier hydrological model in term of runoff generation model and runoff concentration model, analyzes the runoff generation mode from two most widely ablation model (the meteorological factors statistical model and the energy balance model), and enlarges on the runoff concentration model from three sub-models: the surface routing sub-model, the englacial hydrology sub-model and the sub-glacial hydrology sub-model.

从冰川产流和汇流两个水文物理过程出发，介绍了国内外冰川水文模型的研究进展，对目前应用最广的两类消融模型－基于气象因子的统计模型和基于物理机制的能量平衡模型进行了分析和讨论；从冰川表面、内部以及下部汇流3个方面阐述了冰川汇流模型所取得的成果。

Because we use the two factors,γ1 andγ2, to explain monetary policy and another two factors, m and n, to explain market volatility exogenously, these results can characterize the relationships in government bond market between volatility and monetary policy, liquidity and returns well.

实证结果表明，模型中引入利率调整因子γ1、准备金率调整因子γ2及流动性因子m和n作为外生解释变量，能够较好地刻画我国货币政策对国债市场波动的冲击、市场流动性对国债收益率波动的影响及国债收益率波动与收益率的关系。

According to Meese's exchange rate model in 1986, in this paper, we modified Meese's (1986) model and suppose the Interest Rate Parity is untenable, the risk premium factor and real exchange rate parameter are considered, and the Purchasing Power parity doesn't follow random walk, we derive our modified equilibrium model. Base on the State Space Model, we try to estimate bubbles and risk premium which are unobservable variables by Kalman Filter to test which one is or both are the main factors that to cause the real assets price biased from the market fundamental price.

本文是以Meese(1986)所决定的汇率模型为基础，但Messe一文并未讨论到风险溢酬的问题，故本文为了克服此一缺憾，而假设未抛捕的利率平价说(uncovered interest parity，UIP)不成立，以加入风险溢酬因子，且更进一步假设偏离购买力平价理论(purchasing power parity，PPP)不服从随机漫步，若如此则顺利将实质汇率变数纳入於模型中，重新建立均衡汇率模型，为了验证本文所创立的模型，实证方法以状态空间模型为基础，运用卡门滤波器递回法来估计不可观察的变数，以观察台湾的外汇市场上是因泡沫现象还是风险溢酬造成资产价格偏离市场基要价值或是两者皆是造成实际资产价格偏离市场机要价格的因素。

The research applied landscape ecology, integrating land using, ecology networks, and the concept of human needed environment model addressed by Odum to build natural and cultural criteria which are used to decide natural factorsand cultural factors. Subsequently, applying the criteria and planning procedures to category land into agricultural and non-agricultural areas. The agriculture areas include basic grain production areas, and leisure agriculture areas. The non- agriculture areas include agriculture of river corridor ecology restoration areas and remnant cultivates lands. Above all, remnant cultivated lands are separated into wilderness, parks or indefinite areas because of different context.

本研究运用之理念包括地景生态学、整合土地使用、生态网络及Odum提出四种人类需求环境模型；据以研拟自然及人文面原则，进行自然因子(NDVI值、坡度、高度、土壤等)及人文因子之准则建构；再依准则及划设流程规划出农业及非农业区域二类型，其中农业类型包括基础粮食生产区、休闲农业区，非农业区包括河廊农业生态复育区及剩余耕地，其中剩余耕地又依背景因子不同划设为荒野化、公园化或模糊区使用。

The new concept of slaking factor combined by the thickness,temperature, flow rate of green liquor; and the slaker temperature,and number of CaO is presanted, and the closed control is realized with slaking factor as main parameter.

提出了将绿液的浓度、温度、流量以及消化器温度和理论上所需氧化钙量5个参数综合成为一个参数——消化因子的新概念，并以消化因子为被控量进行闭环控制；建立了过量灰与消化因子等参数关系的推断数学模型；克服了120min大纯延迟时间的影响；实现了过量灰最佳值控制和苛化过程参数优化。

The results from the model are in good agreement with the experimental data. Potassium phosphate tribasic、 Potassium tetraborate、 and Piperazine are of obvious active affection for enhancement foctor, where N-methyldiethanolamine and 2-Amido-2-methyl-l-propylacohol are negative ones in all additives.
