The results showed that: 1) the vector normalization method and multiplication scattering correctionmethod were suitable to setting up prediction models for leaf structure and oil, respectively;
结果表明：①矢量归一法和乘法散射校正法分别适合建立烟叶叶片结构模型和油分预测模型；
2
The reasons and the influence of sudden change of the electric power of generators during stability prediction are analyzed. Moreover, corresponding correctionmethod is proposed.
分析了稳定性预测过程中电磁功率突变产生的原因及其影响，并提出了计算修正的方法。
3
Therefore, based on mathematics statistics theory, this thesis presents a new evaluation method for evaluating these predicted results by introducing the notion of the correction rate of prediction.
