Abstract

Combustion, fire, and flame have been observed and speculated about from earliest times. Every civilization has had its own explanation for them. The Greeks interpreted combustion in terms of philosophical doctrines, one of which was that a certain “inflammable principle” was contained in all combustible bodies and this principle escaped when the body was burned to react with air. A generalization of the concept was provided by the phlogiston theory, formulated in the 17th century. Treated at first as a purely metaphysical quality, phlogiston was later conceived as a material substance having weight and, sometimes, negative weight. The inadequacy of the phlogiston theory became apparent only in the late 18th century, when it proved unable to explain a host of new facts about combustion that were being observed for the first time as the result of increasing accuracy in laboratory experiments. This report discusses the understanding and use of "fire" by mankind that is accompanied by the progress of human civilization and social development.

燃烧是人类能源利用的最早形式，“火”的使用使人类摆脱了茹毛饮血的原始生活，对燃烧的认识一直伴随着人类文明进步和社会发展。可以说火的使用是点燃人类文明之花的重要标志。恩格斯所说：“只是人类学会了摩擦取火以后，人才第一次使无生命的自然力为自己服务。”本报告将从我们身边的“燃烧与火焰”现象出发，探讨人类文明发展各个时期与“火”相关的标志性发明，梳理人类对于燃烧和火焰理解和认识的历史，并简要介绍西安交通大学在燃烧和火焰基础研究和教学方面的工作。
