塑料自然老化力学性能的灰色预测

塑料自然老化力学性能的预测研究对塑料制品的设计，应用及改进具有重要意义，在原始数据极少，同时又无明显的分布特征时，难以用回归分析方法进行研究，本文提出了基于灰色预测理论的塑料自然老化力学性能的预测方法，通过实例证实了这种方法具有良好的精度。

Prediction of mechanical properties of plastic natural aging with grey system theory

The prediction of mechanical properties of natural aging is of importance to the design, application and improvement of plastic products. However, it is very difficult to get an accurate and reliable prediction when the data is very limit and its distribution feature is not evident. This paper proposes a forecasting method to predict the mechanical properties of plastic natural aging. The method has been used in a practical example and there is a quite good fit between results and the experimental cures, demonstrating the applicability of this method.
