If want the data of built-in in HTML page of the static state trends, and these dynamic data are the word that will offer by the program such as ASP, PHP, so every time a person visits your website, the server is about to carry out and handle Tongji.asp document, from the data with draw-out and relevant database, reexport shows to the webpage, if tens of thousands of person is visited at the same time, be about to be carried out tens of thousands of times, consequence cans be imagined.

假如要在静态的HTML页面里嵌入动态的数据，而这些动态的数据是由ASP、PHP等程序来提供的话，这样每次有一个人访问你的网站，服务器就要执行并处理一次tongji.asp文件，从数据库抽取相应的数据，再输出给网页显示，假如有几万个人同时访问，就要执行几万次，后果就可想而知。

A dynamic computer simulation model of winter wheat was established from the data of the fields at AUH(the Agricultural University of Hebei) during 2000-2001 and validated from the data of the experiment of nitrogen, phosphorus and potassium at Shenze county during 1985-1986. This model was used for reference of information not only from field data but also from other winter growth and development models.

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。
