During the course of ball milling , there was a rise of temperature , which accord with the value of theory well and proved that there was a exothermic reaction which happened suddenly and completed soon . this ball milling reaction was a sudden and fast self - propagating reaction , not a gradually diffusing reaction 在球磨过程中，检测到有温度突然升高的现象，而且与理论计算值符合很好，可以证明球磨时存在一个突然发生、瞬间完成的放热反应；该球磨反应的是一个突然爆发的自蔓延反应，是瞬间合成过程，而不是一个逐渐扩散的反应过程。
It is shown how control of the melting of the coating on aluminum particles in a mining explosive helps control the split of the total energy released into shock energy , that supports the detonating shock wave and heave energy , that heaves the overburden off the ore body 并在此基础上，对含铝矿用硝胺乳化炸药中的铝粉反应过程进行了理论分析，认为铝粉的吸热和放热反应过程对总能量分配为冲击波能（用于支持爆轰波以及破坏岩层）以及抛掷能（用于抛掷）的比例影响明显。
By control the adulteration of kmno4 powder in the raw materials , we found the adulteration of kmn04 powder decrease the dosage of easy melted metal mn , and release the hot - trap problem , enhance the diffusion velocity as well as cut down the synthesis temperature and combustion propagation velocity of the system 320左右体系内sro _ 2分解放出氧气，并且和空气中的co _ 2发生反应生成了srco _ 3发生强烈的放热反应，缓慢的放热包。 450左右体系内naclo _ 4分解吸热， shs反应被触发，反应剧烈，放出大量的热。
The mechanism of dual activation reactive milling is discussed . according to the mechanism , the mechanical activation from ma and thermal activation from the second high - exothermic reaction system ( ti - c ) are utilized for synthesizing of nanometer - sized tic powder from low - cost tio2 powders . in the process , the mechanical activation is a fundamental 在“双重激活反应研磨”机制中，利用ma过程中的机械激活作用以及所引入的ti - c高放热反应体系所带来的热激活作用，以低成本的tio _ 2为原料合成纳米tic粉末。
The result of experiment showed that the reaction between ti and c is a thermodynamic course , when 2 wt % mg is added to melt , it can restrain the formation of fragility phase al3ti , and gained al matrix composite which contained tic reinforced particles only . because mg reacts with the forms a micro - high temperature field around the oxide around the graphite particles and the oxygen gas which is brought by the immersion bell , and the reaction gives out a lot of heat energy , thus forms many high micro - fields in melt , which prompt the reaction between the al and ti 加入适量的mg ( 2wt )可以抑制tic al复合材料中的脆性相al _ 3ti的产生，生成仅含tic的铝基复合材料；由于活化剂镁在体系中与石墨颗粒周围的氧化物、以及外来的氧反应放热，在熔体中形成微高温区，促进al - ti反应，同时， al - ti反应也是放热反应，因此体系中的内能急剧增大，促使al _ 3ti分解以及ti朝c颗粒扩散，缩短反应的孕育时间。
Noticing that strong exothermic reaction due to large negative enthalpy of mixing can occur among major components of ti - zr - based quasicrystal alloy systems and zr - based bulk amorphous alloy systems , we developed for the first time a new technique for fabricating both ti - zr - ni systems quasicrystal materials and zr - al - ni - cu systems amorphous - based composite materials using laser - induced self - propagating reaction synthesis ( lsrs ) 注意到构成ti - zr基准晶合金体系和zr基大块非晶合金体系的主要组元之间具有很大的负混合焓，因而能够发生很强的放热反应。利用这一特点，我们首次开展了激光诱导自蔓延反应合成ti - zr - ni系准晶材料和zr - al - ni - cu系非晶复合材料的探索研究。
