一、增加一道屏障《高一化学》第页（实验）演示白磷和红磷着火点的差异，《初三化学》第页（实验）则1596-7181-10要说明可燃物发生燃烧的两个条件。虽然实验的目的各有指向，但实验原理和装置却极为相似，并且，在实验中最容易出现的问题也完全一样，就是在白磷点燃后，由于 First, add a barrier “High One Chemistry” page (experiment) demonstrates the difference between white phosphorus and red phosphorus ignition point, “Third Chemistry” page (experiment) then 1596-7181-10 to illustrate two conditions combustible combustion . Although the purpose of the experiment has its own point, but the experimental principles and devices are very similar, and in the experiment the most likely problem is exactly the same, that is, after the white phosphor ignited, due to
