| 摘 要： | 使用500N微机控制材料试验机,利用压痕加载曲线,进行了用针尖压入法测定谷物籽粒硬度的试验研究,测得豌豆、蚕豆、大米、绿豆、小麦、扁豆以及玉米在不同组成部位、不同含水率时的硬度值在2～75MPa范围内.研究表明,试验加载速度在0.25～2.00mm/s范围内、针尖压入深度在0.25～1.50mm范围内时对试验结果无明显影响,而针尖锥度与籽粒硬度存在定量关系. |
| 关 键 词： | 谷物 籽粒 硬度 压入法 试验 |

| Abstract: | By using the 500 N microcomputer control material testing machine,based on the load-depth curve, the hardness of the grains was experimentally studied adopting needlepoint pressing-in method.The peas, horsebeans,rice,mung beans,wheat,lentils as well as corn at different moisture and component parts were tested and analyzed,with the measured hardness range of 2-75 MPa.The research showed that at the loading speed in 0.25-2.00 mm/s and depth of indentation in 0.25-1.50 mm,no obvious effect appears in the test... |
