利用CCD光纤光谱仪，证明了火焰光谱内部的特征谱线是K、Na原子的发射光谱。同时还测量了特征线出现时的火焰温度，指出通过观察特征线是否出现，可以判断火焰温度的范围。实验发现，火焰光谱的形状与燃烧条件密切相关，对碳烟的抗干扰能力较强，包含了大量与燃烧有关的信息。通过对火焰光谱形态的分析，可以判断燃烧状况.
By using the CCD fiber-optic spectroscopy, the paper proved that the characteristic line inside of the flame spectrum is atom emission spectrum of K and Na. At the same time we also had measured the flame temperature when the characteristic line appeared and had poinied out that one could estimate the scope of temperature of the flame through observing whether the characteristic line is appearing or not. The experimeat discovered that the shape of flame spectrum had closely relationship with the combustion condition which had stronger anti-interference competence to the soot, involved in a lot of information related to combustion. Through analysis flame spectrum shape, we could judge the combustion condition.
