本文建立了聚氨酯反应的数学模型,通过计算机对该模型进行了参数估值和检验。用该模型对放大反应结果进行预测,计算结果与实验结果相当吻合。 In this paper, a mathematical model of polyurethane reaction was established. The parameters of the model were estimated and tested by computer. The model was used to predict the amplification reaction results. The calculated results are in good agreement with the experimental results.
