以PE基木塑复合材料的动态弹性模量预测模型为研究对象,利用无损检测的方法对PE基木塑复合材料的动态弹性模量进行检测。将制备方式与实验结果分别利用回归预测模型与灰色理论系统的GM(1,N)/GM(1,N,X(0))模型进行拟合预测,结果表明灰色GM(1,N,X(0))模型对PE基木塑复合材料的动态弹性模量有比较好的拟合能力和相对高的预测精度。
以PE基木塑複閤材料的動態彈性模量預測模型為研究對象,利用無損檢測的方法對PE基木塑複閤材料的動態彈性模量進行檢測。將製備方式與實驗結果分彆利用迴歸預測模型與灰色理論繫統的GM(1,N)/GM(1,N,X(0))模型進行擬閤預測,結果錶明灰色GM(1,N,X(0))模型對PE基木塑複閤材料的動態彈性模量有比較好的擬閤能力和相對高的預測精度。

With the dynamic elastic modulus of PE plastic composite dynamic (WPC) prediction model as the research object , we used nondestructive testing to test dynamic elastic modulus of PE WPC .We used regression prediction model and grey system theory GM (1, N) &GM(1,N,X(0) ) model to forcast the model between the preparation method and the experi-mental results.For PE WPC dynamic elastic modulus of the prediction , gray GM (1,N,X(0) ) prediction model has good fitting ability with high prediction accuracy .
