摘　　要：对石英光纤表面化学镀镍-磷的动力学进行了研究。在相同实验范围内,分别建立了幂函数型和多元二次型动力学模型。通过79个不同因素水平组合所获得的实验数据对两种模型的可靠性进行了比较。结果表明,幂函数动力学模型计算的镀速与实验值相对误差小于5%的有67个,大于5%而小于10%以及大于10%的各有6个,最大相对误差为13.86%;多元二次型动力学模型计算的镀速与实验值相对误差小于5%的有78个,大于5%的只有1个(7.68%)。多元二次动力学模型更可靠。与幂函数动力学模型相比,用Design-Expert 7.00软件中的响应面(Box-Behnken)程序可自动建立多元二次型动力学模型,并判别模型的可靠性及各模型项对镀速影响的显著程度。The kinetic study on electroless Ni-P deposition on the surface of quartz optical fiber was carried out. A power function model and a multivariate quadratic model were separately established within the same experimental range. The reliability of the two models were compared based on 79 groups of the combinations of different factors at different levels. The results showed that the number of relative errors between the deposition rates calculated by the power function model and experimental values is 67 for 〈5%, 6 for 5%-10% and 6 for 〉10%, and the maximum relative error is 13.86%. The relative errors of the multivariate quadratic model are all less than 5% except that one is 7.86%. The multivariate quadratic model is more reliable than the power function model. As compared with the power function kinetic model, the multivariate quadratic model can be established automatically by using response surface （Box-Behnken） program in Design-Expert 7.00 software, and its reliability and the significance of the effect of individual term on deposition rate identified.
