点燃、加热、高温都是化学反应的条件，它们之间的区别是温度的高低不同，以及是否需要连续不断地提供热量。1．点燃是引发着火点较低的物质燃烧时所需要的温度条件，即便可燃物的温度达到着八点。如：常用酒精灯、火柴等外界热源提供热量。热源火焰在接与被点燃的物质接触，在 Ignition, heating, and high temperature are the conditions for chemical reactions. The difference between them is the difference in temperature, and whether or not there is a need to continuously provide heat. 1. Ignition is a temperature condition that triggers the burning of a substance with a lower fire point, even if the temperature of the combustible reaches eight o’clock. Such as: commonly used alcohol lamps, matches and other external heat sources to provide heat. The heat source flame is in contact with the ignited material.
