针对火药随温度发生的物理变化过程难以连续测试的问题，提出了基于高清数码相机和差示扫描量热仪相结合的方法，将少量松散或压实火药试样置于坩埚中，差示扫描量热仪从常温开始以一定变温速率连续升温或降温，并用高清数码相机拍摄照片连续记录试样物理表观形貌，以实现对火药物理性能随温度变化的连续测试，为火药的安定性分析提供了新途径。

In order to find a solution to continuously test the physical varying process of pyrotechnic composition with temperature change, a method based on the using of digital cameras and differential scanning calorimetry (DSC) was proposed, by putting a small amount of loose or compacted composition in the crucible of DSC, which continuously heat and cool the sample from room temperature at a certain temperature rate, and taking pictures with high-definition digital camera to record the physical appearance of the samples. The method achieves the purpose to test the physical properties of pyrotechnic composition varying with the temperature continuously, as well as provides a new way to analyze the stability of the pyrotechnic composition.
