Frictional experiments using a self-designed "multifunction servo friction and abrasion experiment machine" with the multi-parameter synchronous data collection system and online data processing software have been made on six types of rocks. The analyses of the experiments results indicate that earthquake faults with large displacement bring up a series of products continually changing from cataclasis to melting. The rocks contained mafic minerals are easier to melt and the gas bubbles in melting products proved the hydroxy water from the minerals has participated the rock melting process and decreased the melting point of the rock. Frictional melting is more sensitive to speed than normal stress. The temperature sharply increases at about 40℃/sec when the sample enters the earthquake fault state. While the melting happens, torsion decreases instantly and there is perhaps a "blind region" of normal stress.

利用自行设计加工的&多功能伺服摩擦磨损实验机&，及多参数同步数据采集系统和联机数据处理软件，对六类岩石进行的实验和分析成果表明：大位移地震断层作用形成了与滑动速率有关的从碎裂到熔融连续变化的系列产物；含镁铁质矿物的岩石更容易熔融，熔融产物中出现的气泡证实了矿物羟基水很可能参与了岩石的熔融过程并降低岩石熔点；相对于正应力而言摩擦熔融程度对速度变化更加敏感；此外，进入地震断层状态时温度急剧上升达～40℃/秒；伴随熔融发生出现扭矩骤减时，可能存在一个短暂的正应力&盲区&。

Based on the above actuality, this paper studied the high quality incineration technics and theory in a self-designed rotary incinerator. The variation of several operation conditions such as waste feedrate, excess air ratio, air distribution and rotation speed of the fulcra has been employed to study the formation and control theory of NOx, SO〓and HCl. Based on the experimental results, a simple and comprehensive model has been proposed to describe the process of acid gas formation and reduction. The results show that the formation of pollutants strongly depend on the incineration state of the solid waste in the rotary incinerator.
