项目摘要

We see many interesting scientific studies concerned with earth environment science. Above all, global warming caused by the increase of the atmospheric C02 is a global issue. Few studies, however, have discussed or examined the quantitative expression of the relation between them. We have used earth environment science as a teaching material for science or applied math education for some years. During the three years of scientific study on it : (1) We created a computer model of C02 circulation using "iThink," or a system dynamic software. We used the numerical values adopted by IPCC. This model runs on a small computer and features easiness in changing parameters and in grasping the whole connection at sight. We employed a Box model that expresses quantitatively carbon storage, annual moving quantity between the storage units and its mobility. The model enables us to simulate the annual carbon movement. (2) We developed some teaching materials aimed at utilization of Discrete Fourier Transformation. Among them is voice analysis with a graphing calculator. We gave a presentation on it at ICME 10 (2004), and a lecture for a training course of "Science Partnership Program" (August, 2004 in Tokyo, December, 2004 in Fukui). (3) We chose teaching/ learning materials from publications related to global warming, and mainly from Climate System Modeling (Kevin E. Trenberthe, 1992). The model (Refer (1)) is a result of our study on it. We have focused on carbon dioxide circulation on earth. There is much more left for research and discussion.

我们看到许多与地球环境科学有关的有趣的科学研究。首先，由大气CO2的增加引起的全球变暖是一个全球性问题。然而，很少有研究讨论或检查它们之间的关系的定量表达。多年来，我们一直将地球环境科学作为科学或应用数学教育的教材。在三年的科学研究中：（1）我们使用系统动力学软件“iThink”建立了CO2循环的计算机模型。我们使用IPCC采用的数值。该模型在小型计算机上运行，具有参数易调、整体联系直观等特点。采用Box模型定量表达了碳储量、碳储量单元间的年迁移量及其迁移率。该模型使我们能够模拟每年的碳运动。(2)我们开发了一些针对离散傅立叶变换应用的教材。其中之一是用图形计算器进行语音分析。在ICME 10（2004）上进行了介绍，并在“科学合作计划”的培训课程上进行了演讲（2004年8月，东京，2004年12月，福井）。(3)我们从与全球变暖相关的出版物中选择教学材料，主要来自气候系统建模（Kevin E。Trenberthe，1992）。该模型（参考文献（1））是我们研究的结果，我们的研究重点是地球上的二氧化碳循环。还有更多的东西需要研究和讨论。
