结果表明，同属三种植物的形态特征相似，可通过叶形及花期是否具基生叶，花萼的形态，花冠颜色以及茎的生长方式和植株被毛情况等予以鉴别；通过对三种植物的花、根、茎、叶及全草粉末的组织构造观察，认为种间差异较小，可依据毛茸的分布及形态特征和茎的木化程度不同加以鉴别；对三者花粉粒进行了扫描电镜观察，发现其大小和外壁纹饰具有明显差异，为三者的鉴别提供了有力的依据，也为该属的分类及植物花粉形态研究提供了花粉形态学方面的资料。

The results indicate that the cooling rate of melt droplet that can not break further depends not only on its diameter, but also on its position in atomizing chamber. As a result, the same sized particles in different positions show different cooling rates and two different kinds of microstructures. The cooling rates of melt droplets range from 104 to 108 K/s, and the critical cooling rate for glass formation of Al-Ni-Y is about 105 K/s. Moreover, the corresponding maximum diameter of amorphous particles is 25 μm, which accords well to the theoretical analysis results. The new approach, reflecting the complexity of close-coupled gas atomization objectively, is available and effective to evaluate the cooling behaviors of close-coupled gas atomization.

结果表明：在一定的工艺条件下，紧耦合气雾化存在多种破碎模式，熔滴的冷却速率因直径、雾化位置的差异，相同直径熔滴经历结晶和非晶化2种不同冷却行为；依据Al基合金粉末的粒度分布和微观结构，结合熔体的雾化过程及冷却模式，确定熔滴冷却速率的上、下限；实验得出熔滴的冷却速率为104~108 K/s，Al-Ni-Y合金的非晶化临界冷却速率为105 K/s，能形成非晶态的熔滴最大直径为25 μm左右，实验结果与理论分析结果较吻合，比较客观地反映紧耦合气雾化的复杂过程。
