| 摘 要： | 对广西主要水稻品种(桂香2号、特糯2072、优I679)在不同含水率、芽长条件下的休止角以及滑动摩擦角进行了测定。通过对试验数据回归分析,建立了含水率、芽长与休止角、滑动摩擦角的数学模型,分析了含水率、芽长对休止角、滑动摩擦角的影响。结果表明:休止角、滑动摩擦角随着含水率、芽长的增加而增加;含水率、芽长对滑动摩擦角的影响大于其对休止角的影响;同一品种,在相同含水率、相同芽长条件下,休止角始终大于滑动摩擦角。

| Abstract: | The paper tested caesural angle and sliding friction angle of main rice varieties in GuangXi,The test was under conditions of different water content and different length of the sprouting.Regression analysis was carried out by computer,and the mathematical model was established.The influencing mechanism between independent variables(water content and length of the sprouting) and dependent variables(caesural angle and sliding friction angle) was analyzed.The results show that the caesural angle and sliding f... |
