摘　　要：晶化过程电特性的预测对非晶合金组织结构特性有重要意义。文中提出了一种基于小波分解(WD)和最小二乘支持向量机(LSSVM)的晶化动态电特性的模型预测方法。以Cu-Zr-Al非晶合金晶化过程动态电特性为例,建立了其电特性预测的WD-LSSVM模型,并根据数据进行实例验证,结果表明该方法显著提高了超前一步预测的精度。The electric property forecast in crystallization process has an imporfant significance to the amorphous alloy organization property and for this,a model forcast method is put forward in this paper based on a wavelet decomposition（WD） and LSSVM crystallization dynamic electrix characteristics.At the same time,an electric proerty forecast WD-LSSVM model is established based on the Cu-Zr-Al amorphous alloy crystallization dynamic electric property and it is tested througy a real example.The resulf shows that the method improved the superior forecast accuracy obviously.
