采用模式识别与回归相结合的方法总结碳酸化分解生产数据的规律,得到了描述氢氧化铝产品SiO_2含量的数学模型表明在溶液Al/Si不变的条件下,溶液中Al_2O_3浓度高时氢氧化铝产品合SiO_2低,这一规律经小型实验得到了验证。
The regularity of carbonization process for alumina production has been summa-rized by the pattern recognition and regression. A mathematical model has been proposed todescEribe the factors affecting the silica content of aluminium hydroxide product. The high con-ecranttion of aluminate ion in solution will prodoce aluminuium hydroxide with low content ofSiO_2 under the condition of Al_2O_3/SiO_2 ratio kept unchanged. This was confirmed by the auth-ors′certain scale experiments.KEY
