| 摘 要： | 在复杂反应动力学研究中，由等温反应体系中各组分随时间变化的数据，采用三次样条法估计各种化学反应的动力学速率常数迭代初值；并结合应用实例，检验了该方法在锁定动力学常数迭代初值范围的有效性。结果表明，该速率初值比较接近真值。此方法为有效锁定速率常数迭代初值提供一种新途径。

| Abstract: | In kinetics study of complex reaction, cubic spline functions were applied to estimate the initial iteration rate constants for various chemical reactions under a constant temperature with the composition data of the components in the reaction system vs. reaction time. Three cases were applied to verify the validity of the cubic spline method. The results showed that the estimated initial iteration constants were quite closed to the final values. |
