The same methods were used to study toluene dinitration, and the results indicated that the thermal runaway risks of these reactions were low too; prolonging dosing duration was helpful to the conversion of all nitrotoluene; decreasing the molar ratio of nitric acid to mononitrotoluene would make an insufficient conversion; among the given temperatures, rising reaction temperature couldn\'t markedly change the yield coefficient, but lead more heat generation and higher thermal runaway risk.

采用同样的方法对二段硝化反应进行研究，结果表明：二段硝化反应的热失控危险性也较低；延长加料时间，有利于反应完全；而随着硝酸与一硝基甲苯摩尔比的减小，硝化难以进行完全；在选定温度范围内升高温度，产物得率无显著变化，反而易导致放热加剧，增加体系的热失控危险。

Because thermal insulation was in oxygen-riched condition of afterburner and charred layer was porous, oxygenous gas in mixture would penetrate into charred layer and chemical reaction would take place in whole charred layer, which intensified the ablation process.

通过对烧蚀后试件的详细分析，认为绝热层烧蚀过程中燃气流中的氧化性组分会渗入炭化层内部，在炭化层内的孔隙中与材料发生放热的化学反应，大量消耗碳，加剧了烧蚀的过程。

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.

通过X射线衍射和扫描电镜分析手段研究了聚环氧琥珀酸加入前后碳酸钙垢晶型的变化，在此基础上探讨了聚环氧琥珀酸的阻垢机理；考察了温度对聚环氧琥珀酸缓蚀性能的影响，根据Bockris置换模型，计算出中性水质中聚环氧琥珀酸在碳钢表面吸附的热力学函数，计算结果表明：聚环氧琥珀酸在碳钢表面的吸附是一个放热、熵增、自动发生的过程。
