可燃物如炭和硫磺,燃烧以后只剩下很少的一点灰烬;致密的金属煅烧后得到的煅灰较多,但很疏松。这一切给人的印象是,随着火焰的升腾,什么东西被带走了。当冶金工业得到长足发展后,人们希望总结燃烧现象本质的愿望更加强烈了。1723年,德国哈雷大学的医学与药理学教授施塔尔出版了教科书《化学基础》。他继承并发展了他的老师贝歇尔有关燃烧现象的解释,形成了贯穿整个化学的完整、系统的理论。《化学基础》是燃 Combustibles such as charcoal and sulphur have only a little bit of ash remaining after combustion; the calcined dense metal is more calcined but loose. All this gives the impression that with the ascension of the fire, something was taken away. After the metallurgical industry has made great progress, people hope that the desire to sum up the nature of the burning phenomenon will be even stronger. In 1723, Dr. Stahl, a professor of medicine and pharmacology at Halle University in Germany, published the textbook “The Foundation of Chemistry.” He inherited and developed his teacher Becher’s interpretation of the combustion phenomenon and formed a complete and systematic theory throughout the entire chemistry. The “Chemistry” is burning
