The result of the study testifies that the kindling temperature of lumps and scraps of pure magnesium is decided by their fusion temperatures ( the higher the fusing temperature , the higher the kindling temperature ) , and influenced by the heating velocity and the pressure of oxygen in the atmosphere ( the faster the heating and the lower the pressure , the lower the kindling temperature obtained from the experiment ) 研究結(jié)果表明,所測塊狀純鎂和鎂屑的燃點與其熔點有直接的對應(yīng)關(guān)系(熔點高則燃點也相應(yīng)增高) ,并受升溫速度、環(huán)境中氧的分壓的影響(升溫速度越快、氧的分壓越小,則所測燃點值越高) 。
