Successively, stepwise discriminant analysis and artificial neural network were applied and satisfactory results were obtained. 采用人工神经网络法和逐步判别分析法两种模式识别技术，判别结果令人满意。
The results show that the classification model of distance discriminant analysis excellent performance, high prediction accuracy. 研究结果表明，距离判别分析模型分类性能良好，预测精度高，回判估计的误判率很低。
