超高产栽培对稻米品质的影响

以9823和9优418为材料进行超高产栽培,测定了稻米的主要品质指标.结果表明,超高产栽培可以显著降低稻米垩白度与垩白粒率,增加稻米的糙米率和整精米率,对直链淀粉含量和稻米RVA特征值没有显著影响;超高产栽培显著提高了稻米的蛋白质含量、总氨基酸含量、必需氨基酸含量和非必需氨基酸含量.表明超高产栽培可以改善稻米的加工品质、外观品质和营养品质.

On-line Cutting Quality Recognition in Milling Using a Radical Basis Function Neural Network

Tool wear, chatter vibration, chip breaking and built-up edge are main phenomena to be monitored in modern manufacturing processes, which are considered as important factors to the quality of products.They are closely related to the cutting parameters, which are to be selected in manufacturing process.However, it is very difficult to measure directly the cutting quality based on on-line monitoring.In this study, the relationship between the cutting parameters and cutting quality is analyzed.A Radical Basis Function (RBF) neural network based on-line quality recognition scheme is also presented, which monitors the level of surface roughness.The experimental results reveal that the RBF neural network has a high prediction success rate.
