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.

在这项研究中，我们根据第一个设备的构建经验研究了第二种光加热动态DSC。第二个设备的最重要特征是与DSC的炉子分离的轻加热系统。光纤维用于将轻加热系统与炉子连接起来。这种结构导致各种优点。首先，由于具有灵活的光纤，光入射率的安装变得比第一个设备容易得多。其次，样品操作变得更加容易，因为可以从炉子的顶部去除光入门系统。第三，样品的发病率条件和参考侧可以彼此独立控制。这允许各种新的测量方法。第四，将TMDSC添加到常规DSC的能力的轻型加热系统很容易安装在各种公司的DSC Applantuses中。这意味着可以在商业上提供光加热系统。第二个设备有另一个改进。 TMDSC信号通过修改电路直接从DSC设备中的电路中提取。可以获得更好的信号与噪声比的信号。数据收集和数据分析软件尚未完成。但是，我们确认数据收集系统使用测试程序运行良好。因此，在这项研究中解决了光加热动态DSC的构建基本问题。
