| 摘 要： | 本文提出一种新的预报策略，将校准和预报的测量数据结合在一起进行主成分分解，找到校准和预报的共同的正交投影空间。这种新策略用于确定主成分数的交叉验证时只需一次主成分分解，因此速度很快；用于定量预报时，模型稳定性好，预报准确度令人满意。

| Abstract: | A new predictive strategy is proposed in which the calibration set and the predictive set are combined into one set that is decomposed. The new strategy is very fast when the number of the principal components is determined by the cross-validation method because only one decomposition is necessary. In predictive problem, higher accuracy is expected because the model is more stable. |
