The best dosage of dispersant and disperse medium, and the best time of ultrasonic disperse. secondly, the bp neural network process parameters model which describes the relationship between the important process parameters of the preparation of superfine quartz powder and the important evaluate guidelines was built, based on experimentation data. the forecast of the important guidelines was achieved with this model
其次，本文以試驗數據為基礎，基於bp神經網路建立了球磨法制備超細石英粉體的關鍵工藝參數（轉速，時間，裝樣率，料球比）與粉體的關鍵評價指標（中值粒徑，粗端粒徑，均勻性系數）之間多目標多變量的bp網路工藝參數模型，該模型的建立實現了粉石英制備的關鍵指標預測。 -
Thirdly, the weight and threshold of bp neural network model was optimized by genetic algorithm ( ga ), which has stronger macroscopic search and global optimization property, based on bp network model of the preparation of superfine quartz powder. this model is named ga - bp, and improves the generalization capability and the parameters forecast precision of bp network model, and was proved to be correct by both theoretical analysis and experiment
再次，本文以粉石英制備的bp網路模型為基礎，利用遺傳演算法（ ga ）較強的宏觀搜索能力和良好的全局優化性能，對bp網路模型的權值和閾值進行優化，極大地提高了bp網路模型的泛化性能和參數預測精度，將經過ga優化后的bp網路模型簡稱為ga - bp網路模型。 -
