Visual Rice Growth Models system represented an effort to design crop modeling software with object-oriented paradigm and to organize classes in system with model-document-view architecture. Firstly, the crop-environment system was abstracted as many subsystems and physiological processes with object-oriented paradigm while many classes were established to simulate the behaviors of these subsystems and physiological processes. In VRGM, the document-view architecture in Visual C++ was extended as model-document-view architecture for agricultural integrated system. In the model-document-view architecture, document gets the final simulation results by manipulating the models classes and acts as a communicating intermediacy between model and view. Views display the simulation results and translate users' operation and data entering to document. The architecture separates the domain models, data management and user interface.

From this point of view,it ispointed out that there are two kinds of commonalities among diverse prob-lems,one is the relative commonality and the other is the homogenous co-mmonality,and it is advanced that the approach to effectively make useof the relative commonality is to divide models suitably and to set up theorganic relation between models convenient to their composite conection oncondition that models are shared,and the approach to effectively make useof the homogenous commonality is from the view point of different problemsneeding their special models for solving,to convert their special modelrepresentation to comparatively general model depth representation on theprinciple of independence and share of commonality.The articles in thepast has made deep and complete research on model management in aspectssuch as model division and compositive conection,and a number of theoriesand methods are provided,but none of them is in relation to model depthrepresentation.
从这一角度出发,作者指出,在多样性问题中存在两种共性,一种是问题相关共性,另一种是问题同构共性,并提出有效利用问题相关共性的方法是在实现模型共享的前提下对模型进行合理划分和建立便于模型复合联接的各模型之间的有机联系,而有效利用问题同构共性的方法则是从不同问题求解本质上需要的专用模型出发,根据独立与共享原理,将这些专用模型表示转化成较为通用的模型深层表示,以往的文献在模型划分、复合联接等诸方面对模型管理进行了较为深入全面的研究,并从这一角度提出了许多模型表示的理论和方法,但对模型深层表示方面尚没有涉足。

Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.
环境氡主要来自岩石、土壤,而目前环境氡研究中与地质环境结合很少,为此作者以物理场为基础,运用气体运移的费克扩散定律和达西定律,建立起壤中氡浓度分布与大地—大气间氡交换理论模型,首次在理论上将环境氡与地质环境结合起来;论文中从理论上讨论了模型中各参数对空气中氡浓度的影响,发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异;通过面状氡源条件下的氡运移模型实验,研究了介质中氡的运移与分布,实验数据表明氡浓度随深度的变化规律可用指数函数描述,在放射性元素分布均匀的条件下,介质中不同深度和同一深度不同点的氡浓度随时间而变,但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的;同时研究了不同介质间氡的交换,并验证了所建立的理论模型;运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布,取得了较好的效果。

Many researchers have devoted their work to the development of modal analysis extraction techniques in order to obtain more reliable identification of the modal parameters. There are many damping identification methods, but each one has different merit and defect. In order to find which one is the most reliable method with respect to certain characteristics, this thesis focus on how to identify structure's damping in time domain. The following works have been done in this thesis: 1. Investigate four modal analysis methods——the LSCE Method, the Ibrahim Time Domain Method, the Time Domain Collectivity Modal Parameter Method, the Rational Fraction Polynomial Method and improve on the ITD Method in arithmetic.
