分析了影響型砂緊實率控制精度的因素，建立了型砂緊實率-水分回歸系數的動態模型.為防止型砂水分不足或過量，將第一次加水量設定為總加水量的80 .第一次加水后，對型砂緊實率穩定值採用ar模型進行預測，以縮短型砂混制時間.每次加水后，引入修正系數，以適應型砂組成的變化.實驗表明，該數學模型不僅使型砂水分含量在較短時間內達到最佳范圍，同時可指示對型砂組成進行調整，能較好地符合實際情況Abstract : the rules of ganssian light beams extended by lens are disscussed firstey, and the relation between the optimum waist extended and focal distance of the lens are found out
