Abstract:

Gunpowder is one of the four great inventions of ancient China， which once had an important impact on the world pattern and development process. However， after the late Ming Dynasty and the early Qing Dynasty， gunpowder firearms gradually declined in China. Gunpowder moved to the West with the war and became black powder， which promoted the birth and development of modern chemical science. The development of chemical science is of great significance to the dynamite family. The brilliant achievements of China's modern king of dynamite revitalize the glory of Chinese gunpowder. This paper reviews the legendary development course and the groundbreaking role of dynamite， describes the properties， rich types and unique working principles of its special chemical energy， and tries to trace the internal mechanism of gunpowder combustion and explosion. It aims to highlight the importance of scientific thinking mode and the development of chemistry discipline to the study of explosives， so as to continuously enrich the knowledge connotation of chemistry students， stimulate their enthusiasm for innovative thinking， enhance their professional confidence， cultural confidence and national confidence， and promote the spirit of scientists.
