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.

在本研究中，我们研究了第二个光加热动态DSC的基础上，第一个装置的建设经验。第二种装置的最大特点是光加热系统与DSC的加热炉分离，光加热系统与加热炉之间用光纤连接。这种结构导致各种优点。首先，由于柔性光纤，光入射的拟合变得比第一装置容易得多。其次，由于光入射系统可以从炉的顶部移除，样品操作变得更容易。第三，可以彼此独立地控制样品侧和参考侧的入射条件。这允许各种新的测量方法。第四，光加热系统将TMDSC的功能添加到传统的DSC上，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在商业上提供。第二装置具有另一改进。TMDSC信号通过修改DSC装置中的电路而直接从电路中提取。可以获得具有较好信噪比的信号。数据采集和数据分析软件尚未完成。然而，我们使用测试程序确认数据收集系统运行良好。从而解决了光加热动态DSC结构的根本问题。
