项目摘要

In this research we investigated the second light heating dynamic DSC on the basis of experiences of construction of the first apparatus. The most important feature of the second apparatus is the light heating system separated from the furnace of the DSC.Optical fibers were used to connect the light heating system with the furnace. This structure leads to various merits. Firstly fitting of light incidence became much easier than the first apparatus because of the flexible optical fibers. Secondly sample operation became easier because the light incidence system can be removed from the top of the furnace. Thirdly incidence conditions to the sample and reference sides can be controlled independently from each other. This allows various new methods of measuring. Fourthly the light heating system to add the ability of TMDSC to the conventional DSC can easily be fitted to DSC apparantuses of various companies. This means that the light heating system may be commercially provided. The second apparatus has another improvement. TMDSC signals are extracted directly from the electric circuit in the DSC apparatus by modifying the electric circuit. Signal with better signal to noise ratio can be obtained. Software of data collection and data analysis has not been accomplished. However, we confirmed that the data collection system was working well using a test program. Consequently essential problems of construction of the light heating dynamic DSC has been solved in this research.

本研究在第一个装置建造经验的基础上，研究了第二个光热动态DSC。第二种装置最重要的特点是与DSC炉分离的轻加热系统。采用光纤将光加热系统与炉相连接。这种结构带来了各种各样的优点。首先，由于采用了柔性光纤，光入射的拟合比第一个装置容易得多。其次，样品操作变得更容易，因为光入射系统可以从炉子的顶部移除。第三，样品侧和参考侧的入射条件可以相互独立地控制。这使得各种新的测量方法成为可能。第四，在传统DSC的基础上增加TMDSC功能的光加热系统可以很容易地安装到各个公司的DSC设备上。这意味着光加热系统可以商业化提供。第二种装置有另一种改进。通过修改DSC装置的电路，直接从电路中提取TMDSC信号。可以获得较好的信噪比信号。数据采集和数据分析软件尚未完成。但是，我们通过测试程序确认数据收集系统运行良好。从而解决了光热动态DSC结构的基本问题。
