How to Make a Clinker Liter Weight Fired in a Cement Kiln or f-CaO Mathematics Model 建立水泥窑烧成带熟料升重或f-CaO数学模型的方法
The result showed that the grain yield, kilo-kernel weight and liter weight were the highest when N fertilizer treatment was 120kg/ hm~ 2 at the high yield condition. But they had depressed trend when excess N fertilizer applied. 结果表明,在高产的条件下以120kg/hm2施氮的处理,产量、千粒重和容重最高,过度施氮使产量、千粒重和容重呈逐渐降低的趋势,子粒硬度随施氮量增加而提高。
