摘要: 采用PYMJY叶面积仪测量烟叶叶片面积,根据叶片结构对叶丝结构的影响规律,建立了叶片结构与叶丝结构关系模型.结果表明:该模型能较好地预测不同结构叶片切后叶丝尺寸分布,预测自然状态和掺配叶片切后叶丝尺寸分布的计算值与实测值相关系数分别为0.9950和0.9981;利用该模型可为优化打叶过程片烟尺寸分布、提升打叶复烤环节原料保障水平提供有效途径.Abstract: Based on equality in area before and after tobacco cutting,using PYMJY platometer to measure tobacco lamina area and according to the law of cut tobacco structure influenced by tobacco lamina structure,the model of relation between tobacco lamina with cut tobacco structure was set up.The results showed:The model could predict preferably cut tobacco distribution from different tobacco lamina,the correlation coefficent of predicted and measured value was respectively 0.995 0 from natural tobacco lamina and 0.998 1 from mixed tobacco lamina.The model could support method conducting on optimizing cut lamina structure in threshing re-drying product.
