关于燃烧现象的产生并维持燃烧的一般知识,在小学自然或科学课程中同学们已经接触过。在初中化学中,重新学习和探究这个主题在于对“条件”的探究。由于不能对所论及的条件进行比较准确的测定,所以要以不同体系、不同条件下观察到的现 The general knowledge about the occurrence and maintenance of the burning phenomenon has already been met by the students in the primary or natural science curricula. In junior high school chemistry, the theme of relearning and exploring lies in the exploration of “condition ”. Due to the inability to conduct a more accurate measurement of the conditions in question, it is important to observe in different systems and under different conditions
