方法： （1）利用温度可控惰性气氛高能球磨机的机械粉碎作用，制备纳米雄黄；
Methods: (1)Realgar powder was milled in a plenary mill in the operating condition of nitrogen.
高能球磨机的转速不会影响磨球与磨筒壁的脱离点，只会影响磨球对粉体的撞击力及撞击频率。
The ball mill′s rotational speed can only affect the impact force and frequency and has no influence on its separation point between balls and mill wall.
利用模拟球磨机工矿条件的高能冲击磨损实验装置研究了高能冲击磨损中材料的几种磨损机制。
The wear mechanisms of materials in impact wear with high energy were investigated in the paper by using a tester simulating the conditions of mills.
