In the present year, following new experiments were carried out and several new results were obtained. Those resu lts will be published in the future.The new experiments(1) Carbon ion implantation into hematite was carried out.(2) XPS measurement on the hematite was carried out to clarify the variation of chemical bonding among Fe-C-O.(3) In situ observation of high temperature behavior of the carbon implanted into hematite were preformed.From these experiments, Chemical bonding among Fe-C-O atoms in the hematite were gradually changed from the surface. The existence of C-C bond showed a maximum value around 1μm to 2μm, the proportions of C-O bonding and C=O bonding were relatively high. In the region deeper than 2μm, Fe-C bonding was increased, which meant that the carbon implanted into hematite increased the interaction with Fe atom rather than O atom.

在本年度，进行了以下新的实验，并获得了一些新的结果。这些结果将在以后发表。新的实验（1）进行了碳离子注入赤铁矿的实验。(2)对赤铁矿进行了XPS测量，以阐明Fe-C-O之间化学键的变化。(3)原位观察了碳离子注入赤铁矿后的高温行为，发现从表面开始，赤铁矿中Fe-C-O原子间的化学键逐渐发生变化。C-C键的存在在1 ~ 2μm处有一个最大值，C-O键和C=O键所占比例相对较高。在2μm以上的区域，Fe-C成键增加，说明注入的碳增加了与Fe原子的相互作用，而不是与O原子的相互作用。
