  1. This paper is to develop a model on synthesis reaction of methanol using material and thermodynamics balance, and to utilize matlab to solve multielement nonlinear equation set on proposed model, so calculate balance composition of reactions, parameters of various materials, various process criteria such as methanol output and consumption according to given operation conditions, thereby can quantitatively analyze the effect of various operation conditions on process criteria, so that direct the actual chemical operation, thus assist to determine the optimal operating conditions of synthesis, consequently could forecast various criteria such as yield and consumption according to given conditions of feeds

    摘要通過物料平衡與勢力學平衡對甲醇應過程進行建模,並採用matlab工具對所建模型進行多元非線性方程解,以根據給定操作來計算應平衡成、各股物料參數、各主要工藝指標如甲醇?量、消耗等,並繼而定量分析各種操作對工藝指標的影響,以便指導實際化工生?操作,從而幫助確定最佳的成操作工況,並可以根據給定的原料等參數預測成?量與消耗等指標。
  2. Then, this paper empirically tested the validation and predictive accuracy of different var risk management model in the domestic financial market. finally, with the analysis of modem financial risk management development trend and the current domestic financial risk management situation, this paper made a prospect for the application of this model in the construction of domestic financial risk management system. through the analysis, the main conclusions are as follows : ( l ) the traditional mean - variance model is the special example of the portfolio selection based on the var risk management model for the case that the returns of the portfolio are assumed to be normally distributed ; compared with the mean - variance model, the var risk management model is more comprehensive and accurate in the measurement of the portfolio risk, so based on the var model, the investors can allocate the asset more effectively. ( 2 ) the var risk management model can provide the timely and comprehensive risk information for the top risk manager, so it is very helpful to the improvement of total risk management efficiency. ( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions

    通過研究分析,本文主要得出如下結論: ( 1 )傳統的markowitz均值? ?方差模型僅僅是在資產收益率正態分佈假設下基於var風險管理模型進行資產選擇的特例,與均值? ?方差模型中的方差風險度量方法相比, var風險管理模型能夠更全面、更貼切地衡量資產的風險,且基於此模型能夠更有效地進行資產配置決策; ( 2 ) var風險管理模型能夠滿足更高層次風險管理者對風險信息的需,有助於整體風險管理效率的提高; ( 3 )基於var風險管理模型的raroc績效評價能夠映資產管理人的真實業績,從而為金融機構風險限額的分配和激勵約束機制的制定提供統一的標準; ( 4 )國內證券市場資產收益率服從正態分佈的假設明顯不成立,實證檢驗表明基於資產收益率正態分佈假設下的方差? ?協方差模型對國內資產風險的預測存在較大的偏差,由於文中證明在收益率正態分佈假設下基於方差? ?協方差模型進行資產選擇的結果等價于markowitz的均值? ?方差模型,因此,均值? ?方差模型對國內資產風險的預測同樣會存在著較大的偏差,而半參數var風險管理模型則能夠取得較好的預測衡量效果; ( 5 ) var風險管理模型符未來金融風險管理的發展趨勢,基於var風險管理模型建立內容提要風險限額內控體系、風險信息披露體系和業績評價體系,並進行金融監管,將有助於國內金融機構內部風險管理方法和外部監管技術跟上國際金融風險管理的發展潮流。
