摘　　要：本文引入了一种利用物料快速注入法进行动力学研究的新途径。考察了不同的注入温度、注入率和预热程度下进行快速注入对系统热稳定性的影响,确定了新系统对反应条件的适应范围。证明新方法克服了高温高压反应体系中进行动力学研究的一些难点。Short contact time reaction,as a novel method for dynamic researches,was introduced into the high-temperature and high-pressure rea ction system for hydrometallurgical experiments. With the fast injection apparatus,the effects of different injection temperature,different injection volume and different preheat conditions on the thermal stability of the reaction system were studied.Also,the advan- tages of the double thermal couple for temperature measurement and control are discussed.The most suitable working conditions of the new system are recommended as a result of the analysis and discussion of the experimental results.
