The following points are emphasized:The operation models of adiabatic and diabatic distillation have been set up and the operation block, thermodynamics model and mathematical model in the simulation have been determined as well;(2)Based on the simulation and exergy analysis with Aspen Plus program, shortcut distillation design—DSTWU model and rigorous distillation design—RADFRAC model, the author has determined the heat duty, exergy losses and the distribution of exergy losses along the adiabatic column, which will help the simulation and optimization of the diabatic distillation;(3)Diabatic distillation under various operation conditions has been simulated by using energy balance method and exergy analysis;(4)How the different mixture and the various degree of separation, number of trays and feed location influence exergy saving in diabatic distillation have also been discussed;(5)On the basis of the total exergy losses along the column, different schema of the heat transfer distribution along the column have been compared and analyzed;they can be classified in three categories: heat duty equipartition approach, empirical approach, separation degree matching approach. In conclusion, different heat transfer distribution along the column will have effect on total exergy losses. In particular, most satisfactory results have been obtained by using separation degree matching approach. In order to diminish the exergy losses, heat transfer distribution should meet the needs of the request of separation degree.And on this premise, the author makes his suggestion in increasing the proportion of heat supplied to the tray with minimum exergy losses and decreasing the proportion of heat supplied to the tray with the maximum exergy losses.

本文对透热精馏过程进行了模拟并对其节能效果的影响因素做了较为全面的分析和深入的研究,主要研究内容如下:(1)建立了常规精馏和透热精馏过程的模拟操作模块、热力学模型以及数学模型;(2)利用化工模拟软件Aspen Plus并分别采用DSTWU简捷模型和RADFRAC严格计算模型对常规精馏进行模拟计算和有效能分析,确定常规精馏塔的公用工程热负荷、有效能损失及有效能损失在塔内的分布,为透热精馏的模拟和优化提供数据参考;(3)对不同物系在不同分离度条件下进行透热精馏的模拟,分别采用能量衡算法和有效能分析法进行计算和分析;(4)探讨了各种因素如物系的选择、不同分离度、塔板数、进料位置对透热精馏节能效果的影响;(5)以全塔总有效能损失为比较基准,对热量在塔内的三种分布方案即热负荷平均分配法、经验法和分离度匹配法进行了对比分析并得出结论:塔内热量的不同分布方案对于全塔总有效能损失会产生影响,其中以分离度匹配法的节能效果最为理想,为减少有效能的损失,应使塔内的热量分布满足各塔板的分离度要求,并在此前提下,尽量减小有效能损失大的塔板的热负荷和增加有效能损失小的塔板的热负荷。

Among them the influence factor of the stock is mainly: Fund manager select stocks ability, investment style and ability to deal with the accident, national macroeconomy situation factor, the market value of stock usually have the direct influence to the fund net value; To bond part in the net value of the fund, interest rate and the investment ability of fund manager concerns the value level of this part of assets directly, because the securities regulator of our country has made the regulation to the proportion of the fund investment bond besides this, so, this proportion will restrict fund managers investment on the bond either, thus exercise an influence on some value of bond ; Besides stock and two bond, to another important component in the net value composition --The cash, we will all sum up its factor of exerting an influence for the mobile risk factor, namely the risk as a reasult of the exility of cash.

其中股票方面的影响因素主要是:基金经理的选股能力、投资风格和选时能力以及大盘走势与突发事件、国家宏观经济形势因素,股票市值通常受到这些因素的直接影响;对于基金净值中的债券部分来说,利率和基金经理的投资能力直接关系到这部分资产的价值高低,除此以外由于我国证券监管机构对基金投资债券的比例作了规定,因此,该比例也会制约基金经理在债券上的投资,从而对债券部分价值发生影响;除了股票和债券两部分以外,对于净值构成中的另一重要组成部分——现金,我们将对其产生影响的因素全部归纳为流动性风险因素,即由于现金的稀缺而导致的风险。

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.
