实际效应

Based on the existed research, the study found that the selection of these subjects have rarely been studied, so the selection of this theme has significance in the information society geography theory and can rich the tourist sites in geography study and can guide new thoughts. The second part discusses distance decay effects in web sever when attenuation theory be chose in electronic age location. It considers 7 factors: knowledge spillover environment and yi to technological innovation information reaches nature, decision-maker behavior,human capital factor, supply chain environment, yi to the developed communication net and network of communication lines reaches nature, agglomeration factor, commercial and trade circumstance. Part three studies location significance of outdoor sports websites. Though investigating and analyzing our country 30 cities's outdoor sports websites in China, the author gives out the location characteristics of outdoor sports websites in actual geographical space, and take Shijiazhuang for example, the author analyzes the stadiums gathering effection to the outdoor sports websites which are near the stadiums, and dividing the location into gathering area and non-gathering area the author studies the effects for information flow guiding people flow. Part four is the conclusion which includes four conclusions reached by this article.

在国内外已有研究的基础上，发现本文的选题在国内外研究中基本处于空白状态，对于丰富信息社会地理学理论及引导旅游网站在地理学的研究新思维有重要意义；第二部分论述了服务器距离衰减原理在电子服务区位选择中的作用，并分别从知识溢出环境和对技术创新信息的易达性、决策者行为、人力资本因素、供应链环境、对发达通讯网和交通网的易达性、集聚因素和经济贸易因素七个方面进行考量；第三部分通过对我国30个城市的户外运动网站地址进行调查分析，总结出户外运动网站在实际空间分布上的区位特征，并对聚集区与非聚集区的区位在信息流导引人流中的作用—以石家庄市户外运动网站受临近体育场聚集效应的影响为例，作了实证分析；第四部分为结论，总结了本文研究所得出的四点结论。

These improvements result from the fact that nonelastic and nonlinear effects that become significant in the vicinity of ultimate behavior of the structure can be accounted for.

这个方法的支持者认为它导致一个更实际的设计提供了准确的鼹鼠强度超过预期结果的适应服务，提高nonelastic和非线性效应，成为重要的终极行为的结构可以解释为。

For the reduced atmosphere in excessively many carbon dioxide, to our each person, although our strength is limited, but we try to change itself, for instance fosters economize on electricity the custom, countryside Returning farmland to forest, does not overcut the forest, profession few marine pollutions and so on marine transportation, every year participates in the afforestation, little uses even not to use the disposable convenience wooden chopsticks, saves the paper, does not trample the lawn and so on these actual motions to protect the good green plants, causes them when carries on the photosynthesis to absorb more carbon dioxide to help the Earth to slow down the greenhouse effect.

为减少大气中过多的二氧化碳，对我们每个人来说，虽然我们的力量有限，但我们试着改变自己，比如养成节约用电的习惯，农村的退耕还林，不乱砍滥伐森林，海运等行业较少海洋污染，每年参加植树造林，少用甚至不用一次性方便木筷，节约纸张，不践踏草坪等等这些实际的行动来保护好绿色植物，使他们在进行光合作用时吸收更多的二氧化碳来帮助地球减缓温室效应。

The steps are the following:(1) obtain the better model of practical use:(2) determine the prognostic factors synthetically;(3) analyze the effect of the factors through their coefficients;(4) analyze the degree of risk of the factors;(5) reanalyze the important factors.

为此，笔者提出"综合评判"预后因素的方法，其步骤为：（1）获得实际较优模型；（2）全面地确定预后因素；（3）因素的效应系数分析；（4）因素的危险度分析；（5）重要因素的再分析。

Furthermore, how to apply the model efficiently in practice is deeply discussed. As the variance produced by the forecasting model as concerned, the real-time revised method of hydrological forecasting is highlighted. Next arranged, the multi-stratum recursive prediction model is put forward to forecast the error series that is a dynamic system. Later, an error selfregressive multi-stratum recursive prediction model is set up as well as a current algorithm offered. Finally, the difference collated model and the gloss control method, which are devoted to updating the mid-long term hydrological forecasting during the meditate period, are put forward.
