型孔式水稻排种轮充种过程的高速摄像分析（Rice Seeds Feeding Process in Cell Wheel Based on High-speed Photography Technology）
水稻 型孔式排种轮 充种过程 高速摄像
2009/12/28
采用高速摄像技术拍摄了型孔式水稻排种轮的充种过程，分析了充种区内稻种的流动规律、充种姿态以及充种趋势。高速摄像表明：稻种在充种区内主要是沿着限种板一侧向下流动，流动后稻种呈竖立或斜立姿态；在稻种充入型孔的过程中，稻种首先以竖立或斜立姿态充入到排种轮型孔中，其余稻种以平躺姿态填充到型孔上部；91.1％的稻种集中在第2充种区内完成最终的充种过程，因此充分利用第2充种区可以提高型孔式排种轮的充种性能。
真空干燥条件对稻米食味品质的影响（Effect of Vacuum Drying Conditions on Brown Rice Taste Quality）
稻谷 真空干燥 食味品质
2009/11/24
通过食味仪测量糙米理化指标数据,借鉴精米模型,利用系数重估法得出糙米主要成分含量与食味值的关系式。采用二次正交旋转组合设计方案，在控制干燥时间直至稻谷含水率达15%左右的基础上，建立了糙米食味值的数学模型。研究表明， 干燥温度、初始含水率和真空度是影响稻米真空干燥食味品质的3个重要因素,对食味值的影响从大到小依次顺序为干燥温度、初始含水率、真空度，且前二者与食味值呈负相关，后者与之呈正相关。
