摘要
稻米籽粒的剪切特性指标可以用来评价稻米的品质。为此,通过剪切试验获得了稻米籽粒剪切特性的力学指标(硬度、破坏能、破坏力及破坏应力等),并研究了不同加载速度下稻米的剪切特性指标,通过多项式回归建立了剪切特性指标与加载速度之间关系的回归方程,为评定和控制水稻的最后质量提供新的手段和研究方法。
The shear properties indexes of brown rice grain are important in evaluating quality of brown rice. In this paper, the shear properties indexes of brown rice grain including toughness, shear failure energy, shear failure force, shear failure stress were obtained by applying shear experiment, and the shear properties of brown rice grain in different loading rate was studied, the regression equation of relation of shear properties and loading rate were established by multivariate regression, the new method and new research way were improved for evaluating and controlling last quality of brown rice grain.
