摘要
混凝土靶的早期强度的发展规律在很大程度上影响着混凝土靶的后期强度发展规律。灰色系统理论对于小样本具有较好的预测效果。建立了混凝土靶强度的GM(1,2)残差预测模型。结果表明,该模型在预测混凝土靶强度方面达到了很好的效果,有较好的理论和实用价值。
Development regular of the early concrete target is deeply influences it later stage. The grey system theory is good at small prediction effect. The GM ( 1,2) residual error model of concrete target strength forecast is established. The results show that this model is achieve best effect at concrete target strength forecast, and it get better theoretical and practical value.
