摘　　要：论述了利用微机数据采集系统测量分析冷却过程中奥氏体扩散型相变温度的原理和方法。根据相变动力学理论系统地讨论了相变对冷却曲线的影响，由此确定了相变温度。分析结果与实验结果基本相符。The fundamentals and methods forusing computer collecting system to determine phase transformation temperature in cooling were discussed. Effect of phase transformation on temperature-time diagram was analysed. Phase transformation temperatures were determined,according to dynamics of phase transformation. The data computed are in agreement with the experimental data satisfactorily
